Hey guys,, i just put in a 2r Billet exhaust tip on my grizz 550,it sounds good its bit deeper tone but not louder,any body else do this? and is there any problems down the road? thanks.

 

depending on how much it improves exhaust flow, it might cause your engine to run a bit lean. You might need to go to a slightly larger jet...I just don't know if a tip alone will increase exhaust flow enough to matter

 

I put the same tip on my 550 and have had no trouble whats-so-ever. Since the 550 is EFI it will compensate for the exta exhaust if it needs to....DOG

 

Thanks guys for your knowledge,i even like the looks of that tip! lol,, gonna put some miles on it this weekend,whoo yaa!

 

I know of a lot of guys using these without fail. The EFI will compensate fore a small amount of modification but not allot. Congrats on the buy you will love it!
