Do they help any or give us any gains? I saw one in the Stillen catalog for other imports that have intake/exhaust mods and are still N/A.

 

Hey Fred. I have the Stillen catalog and was browsing through it the other day. You could get the fuel pressure regulator, but I doubt it would provide much if any gain in power. It might be nice if you run a NOS setup, but for our NA cars I don't think it would be a good investment. Just to wonder do you still have a resonator on your car? My exhaust is really quiet, but after putting on my ypipe I get quite a bit more noise. I probably won't get a resonator because I figure I bought my ypipe for hp gain Next time I see ya we should compare exhaust.

Yes, I have a small resonator. I took the silencer back. It's really not loud without it. The more I drive the car the more I like the sound. We'll have to catch up with each other one weekend. later
