I need some help with this exhaust set up. I'm going to be running a JDM B18c1 in a 95 dx hatch. I was thinking of an AEM intake, DC JDM 4-1 header, aftermarket cat, etc. However, the exhausts that I'm trying to decide between are the RSR EXMag, Greddy SP2, and the Apexi WS2. Does anyone know if using one of these three exhausts will be too restrictive for the set up that I described above? I'm looking to have a nice sound, a little louder than stock, but with the performance gains to go with it. Is this not possible, unless I go with a straight through design? What do you guys think? I just didn't know if the piping on the catback will be smaller than the header w/2.5" collector. Thanks.

I tried searching, but all I could find is information about the individual exhausts...nothing based on my particular set up.

 

anyone?
