I'm looking to replace my rotting b-pipe.

Stillen says their b-pipe will work on 95-99 models....the same pipe for all models.....guaranteed.

Then I hear from Nissan that the 96 OEM b-pipe is totally different than the 99 OEM b-pipe......different part numbers, different prices, etc.

So which one is it???? Can a 99 OEM b-pipe bolt directly onto a 96 OEM exhaust with no mods necessary??? How is it that Stillen can have a pipe that will work across the board???

Can anyone answer this???
