New Two Brothers slip ons

[hydrovac1]

Just installed my new Two Brothers slip ons, sounds absolutely wicked (deep and loud) but now with such an open muffler, on deceleration my bike does a lot of backfiring. Just wondering if you guys know if putting a pcIII on it and remapping would help at all (not that some backfiring bothers me but it will probably get me some unneeded attention from the local RCMP. Here is a few pics of the exhaust.

Man, that is exactly what I am going to get for my 14. I thought long and hard between Brocks, Muzzys, Two Brothers, and D&D. I definitely want slipons because I prefer the symmetry of two cans. What I've heard on You tube, I love it. Could you post a pic straight from the side so I can see the length? Thanks and enjoy

It might be sucking a little air in at the connection to the stock mid-pipe. Did you use Hi-Temp sealant at the joint. If it doesn't have a good seal it will pop a little on decel as the fresh air may ignite any unspent fuel. Just FYI.... Not good for the fiberglass packing.

Power commander should do it, i`d have it custom tuned also.

I am going for two Akrapovic carbon slip-on exhausts, they sound absolutely fantastic... maybe I'll manage to do an audio file and uploadit over here, or a video. Will keep you informed guys.

Just installed my exhaust and it's popping a bit, but not to bad. Getting it dynoed soon. I will let you know if that cleans it up any more.

theres a line from the air box that feeds air into the exhaust for emissions , put a marble in that line and block it off, it'll help alot

but I like the decel burble

had the same problem with the m4 not that it was a problem but had it dynoed and custom mapped that helped a lot still an occasional pop on decel when pulling a higer gear at low speed..... only when it drops below the power band.
