Two Brothers Exhaust

Just received a Two Brothers can and installed it yesterday. I'm concerned it may be too loud! Their video link here:

Install was fairly simple.

Did you put the optional P1-X power tip on it ?
it gives a better tone not as loud or harsh and improve the mid-range .
There is a youtube video on it

I changed from the P1 power tip to the P1X power tip and it did help but was still a bit loud for the dogs. Called Jim at Big City Thunder and purchased one of his QQ baffles. This is typically installed at the muffler end of a head pipe but I installed inside the TB pipe at the end that that connects to the factory head pipe. Wow what a difference both in mid range and sound. The dogs are now happy.

I installed my TwoBros pipe today with the P1X tip (thanks to the advice of those on this forum).

Nothing much new to add but:

• It should be carbon or black in color but my factory bags do a good job keeping it out of sight
• It is loud when you blip the throttle and/or start it in an enclosed space
• It is much lighter than the stock cat and exhaust and pipe (about a 20lb total weight savings)
  [*=1]TwoBros package is a little over 6lbs
  [*=1]Stock cat is 16.7lbs
  [*=1]Stock exhaust is 10.7lbs

In a couple of weeks I'll have a new map for DynoJets PowerCommander which they will make available online.

-Cheers

I ended up taking off the TB system and replacing it with Lamont's pipe and added the Big City Thunder baffle. With the TB pipe I found the tempture at the head pipe was 30° hotter than Lamont's pipe with the baffle and lost some midrange power with the TB pipe. IMO Lamont's pipe and Big City Thunder baffle is the perfect setup for sound and performance.
