ok, i've been looking at the apex-i n-1 dual for my s13, i've heard many good things, plus it looks sooo awesome, but i've heard two verybad things, and i don't want to belive it. i've heard that it backfires b/c of too much air flow, plus it's too big to fit the rear sway bars. i don't know what to do. i want somethign unique, but i'd sacrifce that for an exhaust system that adds hp, sounds really deep, adn is good for my car. i was thinking tanabe racing medallion. well if have any suggestions it would help a lot thanx
