Hey bro, I ended up installing Z1 non resonated test pipes, at least for now. I was really back and forth w/ the long tubes. It's just not a real cost effective mod. New, quality long tubes are at least $1k+ not including installation and provide minimal gainz over non resonated test pipes. But the long tubes do provide max gainz on the exhaust manifold. If you have money to blow, i'd say do it. I'm still not tuned as of yet. But the car does feel and sound more aggressive. Still trying to figure out my next move. Headers, e85, throttle body, 75 wet shot of nitrous, etc. Let's see. lol
