The bike I just bought (2000 f4) had a Two Brothers carbon fiber slip on installed by the previous owner and I know absolutely nothing about them. Can anyone give me any info from personal experience about the pipe? Does it give the bike a boost in performance at all? Or is it just loud? Are there baffles in the pipe and how frequently do they need to be replaced? Any information will be a big help.

 

I have the same pipe on my 01'. Its not going to give your bike the performance of a full exhaust, but you will notice a slight difference in power. I think it sounds great. Two brothers is a gooood brand.

 

we replace baffles?? what non sense is this? lol

 

I have the same slip on on my bike and I love the sound. You will never get a big boost in power with just a slip on, but they look and sound cool. There is fiberglass wool type packing in the pipe and it will get louder as that brakes in, but that's a good thing. Two Bro's is a damn good brand.

 

thats what a slip on is for, not much power, but a different look and a much better sound
