i have a 94 gsr with a powercore header and cat(i think the collector is 2.5 inches). i needed clarification on fit. does the bpipe only need to be lengthened if your using a stock cat? i bought the rear section, bpipe, and cat, so does the bpipe still need to be extended?

 

i believe so; the headers are also different lengths between 94-99 gsrs and 94-01 everything else. gsr headers are shorter.

 

i have a 94 gsr with dc headers.....a test pipe i got off ebay.....and type r piping from the testpipe back and a type r muffler......its soooooo quiet and when u step on it ....its give a nice deep low tone thats not loud at all.....to me it sounds like a rsx-s. im puttin a video up soooon.

 

cant wait for the vid
