Up for sale is a pair of NHP muffle bypass pipes that came off of my Porsche 996. The NHP pipes are better than your average Fabspeed and Ebay bypass pipes because they are a bit longer in tubing, which provides additional back pressure and reduces the volume a little bit. Also These bypass pipes let you use you OEM exhaust tips, clamps, etc.....

I paid $325 for them: http://www.ebay.com/itm/Porsche-996-...589508&vxp=mtr

They are lightly used and have no issues whatsoever. I'm asking $190 shipped.

Thats a bargain.

Yup, just trying to pass on the savings to my fellow Rennlisters. I wish I could keep them but they're too loud when combined with my cat bypasses lol. So for now I just run with cat bypasses and Fabspeed Supercups.

I should add that with cats they are a bit quieter than the traditional Ebay bypass pipes and have less drone due to the additional length of the tubing. These are awesome for somebody who wants an alternative to the bypass pipes that most people are selling......

Those are sweet! I bet they fit better than shorter muffler bypass pipes. AND it appears you can use factory tips if you want. Do you have any sound clips?

Sound clip would be great.
Do they cause a CEL?

They certainly do fit better than Fabspeed and Ebay pipes, which are really designed for the 02+ rear valence. Ebay Fabspeed pipes just look plain weird on 99-01 cars as the tips stick out too far...... In the end there is nothing better than using your oem tips and having oem fitment......


These will NEVER cause the CEL to come on as the mufflers come after the emissions system (cats).

As for sounds clips I don't happen to have any of my car, however, they don't sound that much different than traditional bypass pipes, other than having a bit less drone than the Ebay/Fabspeed pipes from 2500-3500rpm. There are tons of muffler bypass clips of 996's on Youtube.
