Two Brothers Pipe
« on: June 06, 2011, 05:44:45 am »
Upgraded from my '01 to an '08 Connie and just got a hell of a deal on a 2 Bros pipe set.
A few questions for anyone using this setup.
How much less beneficial is it to use just the slip on exhaust as compared to using the header pipe that comes with it?
Any HP or audio differences?
Second thing is, were any changes needed or suggested as far as adjusting the EFI or anything?
I know a lot of guys with Power Commander setups, have to remap them when piping a bike.

Thanks in advance  ;D

 Are you talking about just a Two Bros slip on can or a full exhaust system? Just installing a slip on can does not require anything additional. The bike can compensate for the slight changes in fuel management. But if you remove the secondary valves (butterfly), yes you will need to add a fuel management system. Just replacing the OEM can with the slip on will lighten the bike substantially. But the two bros is louder than the OEM, very quiet can.
 If it's a  full exhaust system you are talking about. It will lighten the bike even more (as will just a can). The bike will run cooler because of the catalytic converter in the OEM header pipe.  So the new exhaust will be more free flowing. More than likely it will be louder than the OEM system/can. It will also probably force you to modify or remove the center stand. Although  from what I understand, Muzzy sells a modified center stand (on a core basis). I'm not sure who else sells them. But others have just modified theirs.
 Because you have changed the full system. It will require a different fuel management, since the OEM will run way too lean with the after market system. So a power commander, juice box, etc. will be required with a mapping to run this system properly on the bike. Not using one will probably make the bike run lean. Which could result in engine damage.

You didn't mention if it's a single or dual exhaust system.

If it's a single, then it should not require the center stand mod.  If it's dual, both the center stand and the side stand will need to be changed.  Also, you will need to come up with a hanger for the left side muffler.

One thing you can be certain of, it will be LOUDER!.   :-\

Hey guys, been away many moons and never got back to read the replies.
Its a single exhaust and the biggest hassle I had replacing the whole pipe and can, was getting the friggin old one off.
Long allen turned the clamp loose right off, then the pipe decided to glue itself to the headers.  ::)
It does sound a bit louder at an idle or a slow acceleration.
When she comes on the pipe, she sounds mildly nasty. >:D
Very happy with performance and they way it sounds.
1st off, this doesnt need any more balls.
Its like a stocky missle on wheels.
Again, mine is a 2008 ABS model.
Just hit 5000 miles since I got it in May.
Back tire is shot.  ;D Just bought a set of 023 Battleax from Chaparal for 239 delivered.
Front one has a funky wear pattern as did my last Connie, the '01.
Like a narrow high spot on the tire dead center.
Almost like it was way harder than the sides were?
