I just put a 2 bros slip on on my 929 and it pops a lil when I lef off the gas, seems to be slight back firing. From what I know a slip on can make a bike run lean. Do I need to get a power commander and re map the system? Or is there another.... cheaper way to fix this problem? Thanks, Josh

 

Getting a Powercommander is pretty standard with a new exhaust. There is no cheaper fix. If you cant get a PC yet, you might be better off going back to the stock can until you do.

 

get a PCIII and get it tuned!

 

you say I might be better of with the stock pipe... is that because of loss of power or can it actually hurt the bike?

 

Itd not going to run right. Most likely too lean and that can hurt the bike.

 

Well then back on goes the stock pipe. Thanks a lot guys! By the way, It's for sale! check it out in the for sale ads!

 

It's not backfiring. That is the PAIR valve injecting air into the exhaust to burn off unburnt fuel when you roll off the throttle.

You don't need a powercommander with a slip-on, and the sound is completely normal. Don't worry about it.

well that's good to know because I didn't want to pull off the pipe, it sounds way too nice, haha. Thanks so much!

 

no problem man;

& definitely better than spending $300.00 on a PC3 when you don't need it

 

haha, hell yea!
