Which slip-on?
« on: October 18, 2018, 10:53:24 pm »
I'm ready to take the dive into a new slip-on exhaust as I really want to lose the stock muffler. I have done a search on this, but I am looking for some additional info to specifically have these questions addressed if possible:

Best value out there?

Quietest at idle without having to use a baffle?

Make and model of your own personal preference and why?

Best length and any heat issues?

Overall fit, longevity and rebuild-able?


I'm considering Two Brothers, Delkevic, and open to other suggestions...

Just going off of simple looks, I'm liking the Delkevic 14" round CF, but concerned there may be increased noise and heat on the bags from the shorter pipe...

Thoughts?


Thanks!

I purchased the TwoBrothers CF slip-on for my 2008 c14
It was a nice piece of equipment with attach points at collector, mid-pipe to frame and can strap
That mid-pipe attch point wasn't an advantage, whatsoever
Very nice quality, fit and finish $320 in 2009 and it sounds great but they all do
AreaP slip-on was $50 more and was out-of-stock
AreaP didn't have eye appeal of TwoBrothers but I wasn't after looks, I was after cost and availability
I preferred the AreaP, actually

I purchased the Delkevic 18" CF oval for my 2016
It's a nice piece of equipment with attach points at collector and can strap
It fits well, better fit, closer to the bike than the TwoBrothers
It terminates at the end of the bag and clears underneath by +1"
The Del was $240 last year, May 2017 compared to $540 last year May for TwoBrothers and AreaP
The math wins on that one for me
I wasn't after looks
It sounds nice with or without baffle
I run with modified 22mm-through baffle

Delkevic 17” Tri-oval.

Not the cheapest, but the best looking. Quality is there, quiet at idle, but some growl when ripping it, especially with the baffle out.

You can pay more for the AreaP, but unless your going with a full system, I don’t see the point.

Thank you for the replies. I think I am going with the Delkevic. Just have to decide on which model...

Delkevic user here, definitely best value for your $$! Support is fantastic and I recall they pop in on the forums to help on occasion. I removed the baffle and couldn't tell in db or hp increase. Whatever you choose, most folks definitely agree it's a weight savings and better look than stock.  :beerchug:

I had the Delk 18" CF Oval on my bike and ran it on the dyno with the stock exhaust the day I swapped it.

With the baffle in it lost 1.1 hp and gained 0.2 #tq over the stock exhaust. With no baffle it gained 3.5 hp and 1.7 #tq over stock.

The Delk with baffle in at idle gained 4 db. over the stock exhaust and 3.4 db. over at 3000 rpm's.  With no baffle it gained 6 db. at idle and 7.4 db. at 3000 rpm over stock.  With and without the baffle, it gains an additional 10 db. going from 3000 rpm's to 6000 rpm's.

Measured about 3' from the back of the exhaust, it was 70 db. at idle with the stock exhaust, 74 db. Delk with baffle and 76 db. no baffle.
It get's up to 97 db. at 6000 rpm's, Delk with no baffle and sounds SWEET!

I still have the piece of rope I used to measure the distance so I could check the decibels on the stock and Delk exhaust's, one day I'll have to check the ZX14 Full Muzzy exhaust I have on now.

Clip67, I can't explain this but you will find that any muffler made from carbon Fiber will be cooler than the same muffler if made from Aluminum.
I have 2/18"/oval/carbon fiber Area P mufflers on my Connie. Love the sound!

Ride safe, Ted

Thanks Ted!

I'm happy to hear that as I went with a Delkevic 14" round slash cut CF slip on... I ordered straight from Delkevic, and it shipped for free.

Should be here in a couple of days!  :)

For future reference, I'm local for Delkevic. I can pick up your slip on and test it out for a "couple" of months, no charge. Make sure it works properly. Just wanting to help my fellow Coggers out...    :))

Clip, after you get it on the bike, consider joining COG and come to next years National Rally in Pennsylvania.
We'd love to hear how it sounds, and I'm sure you'll enjoy riding with us...
Should be over 100 Connie's there...

COGgers are pretty decent folks...
  Look me up. I'll be the guy on a red Concours.. <sly grin>

Thanks Ted! I'm very likely to do that. I see that next year's rally is in Williamsport, PA which is less than an hour north of me.
