I was looking for a good exhaust upgrade for my Integra LS. I could of swore that the Type R 2.25' B pipe would bolt up to my LS Integra. This email I got confused me and I had a feeling it was BS.
The Type R b-pipe would only bolt up if you swapped out the muffler, cat and the the a-pipe. It will fit under there but you would have to redo the whole exhaust system. If you are interested in doing the whole system let me know I would be more than happy to set you up.
