I want an exhaust. OK i searched this topic. So i leave the first 2 cats alone, and from there i should get 2.5" piping(mandrel), no resonators, to an x-pipe(custom or no?), then to the mufflers. I dont know which specific mufflers to get. I heard Borla,flowmaster, and Magnaflow. Please help me with my exhaust!

 

well have you checked out www.intellexual.net they should have some sound clips of exhausts, so just match it up with whatever you're looking for, the things you listed should do fine with the xpipe custom, you can delete your resonators if you're okay with really high sound output. i personally have magnaflow street series 14289's and they sound mean, they're meaner on a v8 engine, but yeah good luck in your mods

 

here's a good thread on the exhaust set up for the SC400:

I bought Magnaflow (2) 14289 mufflers for under $190 shipped at hotexhausts.com
