How will the combination perform on a JRSC Prelude? Any input? I am currently running a DC sports header and I know it sucks. Any suggestions is welcome.

It's hard to say. There haven't been many dynos with the header, and I've never dynoed mine with my 2.5 inch exhaust, and it's on it's way out now as I am planning on returning to the stock exhaust (my exhaust is too ****ing loud).

I can tell you that when I paired my Kami to my stock exhaust and cat, the max boost pressure increased and I had to pull more timing to avoid detonation. What that has told me is that it's probably not a good idea to have a header downpipe that is larger diameter than your exhaust: it impedes flow.

Thanks a lot for the info. I know the RSR EX mag is a bit bigger piping than stock. I would suggest you look at that exhaust as an option since I am currently using it and it is really mellow rumbling sound. Actually, the supercharger whine is louder than the muffler even with the straight pipe.

Nah, I'm going to stick with the stock header and exhaust. I just picked up a bolt on Random Tech cat for in between. SS will = Super Sleeper.

That is cool. With my setup only thing I can hear after 2nd gear is the charger. I almost went custom 2.5 all the way but I use to have the Apex Dunk and I know it gets annoying after a while. By the way, are you using the stock radiator? If so, what is the coolant/water mixture on it? Also, how much water wetter should I use? Does it even help? Thanks man.
