Anyone have a secondary bypass or J-pipe for sale? Or, who's got a good price on a new one?
Has anyone tried bypassing the secondary, Cat AND Primary bypass? How much louder would it be bypassing all three?

Eric,

I have the secondary bypass on my 90 C2 Cab and am pleased with it. I tried the primary bypass pipe with the secondary muffler attached, but like the primary muffler with secondary bypass better. Also, some of the people I work with have commented that they like the way the car sounds.

I tried the cat, pimary AND secondary bypass (no muffler) and it was very loud.

I can try to post a sound file of my set up if you'd like to hear it.

Do a recent search for G-pipe/J-pipe and secondary bypass. I just fitted mine (it's great! Do it!) and there have been a few recent threads about noise/torque/hp.

Eric,

If you look on Rennlist classifieds, someone lists a cat bypass for sale (sold), however, he indicated in an email to me that he has a primary bypass for sale too. (no affiliation).

You don't want to replace your cat, primary, and secondary with bypass pipes, as it's reported the stock engine will actually make less horsepower. So leave one of the mufflers on. There's a very good article on engine mods in the August 1999 PCA magazine Panorama.
