Hey guys, i'm looking to buy a new exhaust for my FA5....and i really like the 5Zigen A-Spec Catback and the AJP Catback. The 5Zigen is $665.99 and the AJP is $599.99. What do you guys think? I don't really know much about the 5Zigen but i've heard a sound clip on another car, and it sounds hella nice. The AJP is a 3" piping, but it comes with a 18" Magnaflow Resonator, and it's quieter than the GReddy Ti-C. That's what AJP said when i emailed them. Well what do you guys think?
