Title: quietest swlipon exhaust
Post by: bob on June 25, 2011, 05:10:39 pm
from experience. my main concern is highway drone. most of the pipes on youtube sound basically the same. jmho'
I know it will be louder than stock. of all the pipes i've listen to, the Bos GT street exhaust ranks #1 to my ears,

I wish someone would make an aftermarket slip on that looked better than the OEM, but was just as quiet as the stock can is. I'd buy it in a heartbeat.

Nobody has tried them all, so there is no way to answer your thread! The Area P was pretty quiet. But it had a very slight drone on the highway (that I noticed). So I went back to the OEM pipe. If you want quiet, it is pretty much the only choice, OEM. If you want the lowest amount of noise in a aftermarket can. Well then the Area P is one of, if not the quietest can you can get. And is worth a look!

Like Fred, I like the quietness of the stock pipe. Is anyone running a reflashed ECU that opens the flies sooner and running the stock stealth muffler? I think that is what I want. I may miss some hp gains but keep the stealth factor.
Two Brothers and V&H offer inserts to quiet the sound but I imagine the inserts take some HP away also.

Post by: wally_games on June 27, 2011, 04:19:32 pm
I've swapped some emails with pipecity.com and they say the quietest is the Leo Vince SBK as it comes with the insert already installed. It can be removed easily if you want more volume. There are several YouTube clips out there.

I think I'm going with the V&H CSOne, but getting the insert to make it quieter. I'm mainly looking for a better looking exhaust (my main concern) with only a little bit better sound and without a lot of extra volume. If anyone has run this configuration, please let me know your thoughts.

Post by: Zman on June 27, 2011, 04:40:41 pm
I agree the CS One is the best looking, I could not find a sound clip anywhere with the insert.

I was hot to buy one this weekend and took a ride last night and kind of appreciated the stealthiness of the stock can.

I'm with Fred & Bob, if V&H would make a quiet one,,,,,,,,, I'd be all over it.

Send Vance and Hines and email and let them know how you feel. I bet if they get enough requests they make a quieter version of the CS One.

The Leo Vince SBK Slip On is pretty darn quiet.    It has been epa approved for on street use which is different from a lot of off road only pipes out there.  I honestly can't remember now what the bike sounded like stock, but have never whacked the throttle and thought I wish it were a little quieter.....

I have no experience with Area Ps on the the Connie.  But, I had a dual set up on my 2007 ZX14 and it was louder than anything I've experienced.  And, I rode for a decade with open pipes on Harleys. 

Bob may have more experience than me with Area Ps on the C14, but those cans are WAY LOUD on my ZX14.  But, I had to use ear plugs on every ride ... never had to do that before on any bike.

I'm running a Holeshot single can/mid pipe on my bike presently.  It is pretty nice around town, and down the road ... but, if you crank the right hand, it will come alive.  Not obnoxious by any means, tho.  Just a powerful sound IMO. 

But, Area  Ps are just straight thru cans.  The wind from them will blow your hat off.  It was done with my friend when I hooked up the APs.  I can't imagine Area Ps being different on th C14 than my ZX1400.

Based on all I have read I think I'm going to do the ECU reflash and leave the stock can. The guy I bought it from painted it all flat black, and my bike is black so you don't notice the size as much.

Lipstick on a pig,  a paperbag and a six pack of beer,  perfume on a monkey's butt.  Sorry Mick, it isn't going to help that much.  Especially if you ever intend on riding without your saddle bags.  There are some lighter, quiet, better sounding, better performing options out there.  But, then again, who really cares how it looks?  You don't see it when your riding.  My guess is it is just a matter of time before you convince yourself to ditch the anchor.  If it bothered you enough to mention it, it will continue to weigh on you.  Literally.

I been riding for the last week with a new Vance and Hines CS One. At highway steady state speeds the noise is not noticeable, it is only when one runs it through the gears that the noise becomes noticeable and then it is a good noise. The thing I miss over the stock pipe is that I can no longer drop down 2 or 3 gears without anyone knowing. Currently I do not have a silencer installed, I think I may buy one and see how I like it. I have heard it make the exhaust noise deeper.

I must really have no sense of style as I just don't notice how bad the stock muffler looks ('10). Am I really alone here? I do notice it's size when the bags are off. Still most of the
after market ones with the flat end caps (or the minimally tapered ones) look just like car mufflers only smaller, in other words U G L Y. Is there a course I can take to get the sense of style
that I'm apparently missing, or is this really all about the noise and I am just too naive to get it?  ???

Post by: Jagman on July 28, 2011, 05:38:43 pm
I love my Vance and Hines CS1 on my 2011.  It has a very rich and subtle purr at idle but will give you a real nice performance growl when twisting aggressively.  I do not find that this pipe drones at highway speeds at all.  I will also say that I kind of miss the stealth quietness of the stock can but not enough to put it back on.  Still working on  a way to get Guhl a MAP so he can reflash with the VH can.
Title: Re: quietest swlipon exhaust
Post by: Bagger on July 28, 2011, 08:17:14 pm
My "Full Monty" Muzzy dual carbon fiber system (along with the modified center stand) has arrived.  I'm excited about hooking it up.

But, 1st, I want to do a dyno run with the present ECU re-Flash and the Holeshot slip on to get base line numbers.  The bike runs terrific in present trim, I must add !

Once the Muzzy 4-2-2 is installed ... I'll do another dyno run to see where the number map out compared to the initial run. 

Then, I'll ship the charts off to Joe at Dynotronics to see if we need to 'tweek' the ECU with the new set up.

May take a while getting the dyno run, hooking up the Muzzy 4-2-2 and then running a new dyno again.

I'm not all that savvy about dynos.  I figure just a base line horse power and torque is fine.  What about O2 sensor stuff?  Or, anything else that may be of interest?  Please give me some feed back regarding what I should have done on Dyno Day.

Thanx.

I researched this subject to death before settling on the Area P CF slip on. At the time it was deamed the quietest available. I cannot hear it on the hiway even without the saddle bag over. That's with wearing a full face helmet and ear plugs. Sounds like a deep, mellow superbike when you really wind out the motor, no flies, PC3. 35,000 miles later and it sounds the same. I could not be happier. Thanks Area P !  :)

My used 2009 C14 came with a Two Brothers carbon fiber slip-on. It just sounded loud and weird coming off 16 years and 4 Harleys. I guess it must appeal to someone. It also popped on deceleration and engine braking. My 2011 stock pipes stay right where they are. I really couldn't notice whatever loss of actual HP there was. But it rides so quiet all there is is wind noise. That is a blessing I can appreciate. I wear custom earplugs under both Shoei full face; one flip the other fixed. Granted under 65 the wind noise may be tolerable but cruising at 85+it's probably loud enough to cause damage during prolonged exposure, thus the need for plugs even with the stock exhaust; even factoring in goin deaf at 61.

Okay guys,
I did the reflash and Area P slip on. I'd say I like the bike about 30 percent more in terms of performance, sound and looks. Thanks for your tips. The mods only took 1.5 hours working slowly. The easiest mods I have ever done.

Mike I was under the impression that Guhl only flashed the ECU for stock exhaust.  I have been wanting to send him my ECU from my Vance and Hines CS1 equipped bike but he doesn't have a specific MAP for it yet.  Did you just do the reflash for the stock exhaust on your Area P bike?
If so, sounds like what I had actually thought; that since my bike runs very well with the CS1 with no fuel adjustments etc, that the stock exhaust reflash should work fine for aftermarket.  Having said that I do have a very minor amount of decel pop with VH but not bad.
Title: Re: quietest swlipon exhaust
Post by: mick6777 on August 07, 2011, 09:30:58 pm
Jag,
I'm not as into the details as some. I wanted low end torque that I knew was missing, and has been missing from every stock bike I have ever owned. I consulted my friend, who is on here, Tundra Tom. He recommended butterfly removal and an Area P. Then someone else recommended the re-flash. That was appealing because I didn't have to tear the bike apart.  When I do the basic mods of PC and slip on, I'm very happy. That is enough for me. I don't run dynos and go crazy into the details, but I'm grateful to those that do. I do my research, go for what I believe to be the best mods, and that works out great for me.  I spoke to Don about using an Area P slip on, and he assured me I would get a noticeable improvement. He was right. I'm not sure what map he used, but if you call him he is very friendly and will answer any questions you have. Interestingly he said the Area P full pipe actually performs slightly worse, which made the decision to do the slip on a real no brainer! Compared to doing a jet kit or even a PC this is way easier!

Mick
Title: Re: quietest swlipon exhaust
Post by: Jagman on August 08, 2011, 12:39:38 am
That is a great looking pipe! 

I have spoken to Don and to your point,  he didn't say his stock pipe map wouldn't work well on my CS1 equipped bike, he just asked "how is the bike with the slip on running now?"  Seem's like a reasonable question when considering whether or not his re-flash would work well for after market slip on's.  He and Fred H have basically said the same thing; that it was likely the stock map would work just fine for the majority of slip on's but to gain maximum performance a map specifically for that muffler would be ideal.  My experience in the past has been that slip on mufflers do not require much if anything in the way of fuel mapping, only when you full exhaust changes are made is it abolutely necessary to re tune.

 I'm very eager to get it done though, even have considered putting the stock can back on.

Hey, I have an idea. If you want a motorcycle for the sound of it, go buy a Harley. I love the way mine sounds and love the way it rides even more. I do believe I will keep my Kaw C14 and quietly blow by the loud Harley riders. :)

Post by: Peter on August 14, 2011, 07:31:57 pm
I recently put the Area P Carbon slip on pipe on my 2011 C14.  I love the looks, it is a very good quality pipe, and went on smoothly by following the directions supplied.

It is barely noticeable in sound from the seat while riding, and at idle has a nice sound.  It does seem to have gotten a bit louder after putting some miles (perhaps about 1,000) on it, but it is not annoying.  Sometimes I wear a half helmet and it is not objectionable with that on either.

I had noticed the inside rear corner of the right bag got VERY hot with the stock pipe, and with the Area P just slightly warm. 

Area P claim a 15 lb weight reduction and I would tend to agree.  The stock pipe is VERY heavy comparatively.

Honestly if the re-flash would have been available "back in the day" I would have gone that route. As it is I'm still satisfied, the C-14 really is muted on the bottom end as stock.

Ok. I recorded two short videos with the new Leo Vince installed; one with and one without the dB insert. This exhaust comes with the insert installed at no extra cost (unlike the other slipon options) There's also one of the stocker, for comparison.

I really like this exhaust with the insert installed. It has a nice sound, not too loud, and doesn't drone while at speed.

You're quite welcome. Glad they could help.

I rode last weekend with the insert installed. It's very quiet (not potato launcher quiet, but...) and I liked it a lot. I'm going on a trip this coming week and I pulled the insert just for grins. I'll be taking it along just in case I find it to be too loud without it. I'll post my impressions when I get back.

Our trip to Deal's Gap this week got re-routed due to weather. I removed the insert from the Leo Vince today on some great roads around Eureka Springs, Arkansas. Barely heard it although there is a nice burble on decel. I'll probably put it back in this week and see how I like it, but the insert made it very on my test rides last week.
