X Pipe Fabspeed

Hello

OK or NOT OK to put only a XPIPE FABSPEED without the primary sector(primary school,Primary) FABSPEED on M3 E92?

Assembly(Editing) with primary sector(primary school,Primary) OEM only by bolt without cut and weld?

Thank you for your help(assistant)

If you mean re-use your OEM cats on the Fabspeed X-pipe, yes it is possible. You just cut your OEM x-pipe, then clamp it to the Fabspeed X-pipe section.

If that's your plan, I would also suggest the Challenge as possible alternative, just because it costs about the same, challenge has a history of high quality, and it replaces more piping while still re-using your OEM primary cats (so you'd still be cutting, same as the Fabspeed X-pipe).

They'll both end up fairly similar in nearly every aspect though.

Hopefully Challenge doesn't mind me borrowing stuff from their thread.



Features:
- Full stainless steel construction
- 2.5 in Piping
- Twin resonators for noise and drone reduction
- Retains factory primary cats
- No check engine light
- Flanged design for easy installation and upgrade options
- 10 wheel hp and 15 ft tq gains with factory exhaust
- Increased low end power

With any X-pipe, the noise gets noticeably louder. It depends largely on the mufflers that you have. If you are putting Fabspeed or Challenge X-pipe replacements on your OEM mufflers, seeing that you're still using OEM cats and both X-pipes come with resonators, it should be louder, but probably not enough to anger most police here in the states. Don't know about France though.

Now, if you have this X-pipe setup with Race mufflers, that's probably going to be MUCH louder.
