I'm going with the new SLP design, I want the coating and lower under hood temp. But ARH look awesome to, I bet you really can't go wrong with either, or maybe just splurge and get some nice pacesetters, LOL

Usually we see between 25 to 35 with a tune every car is different and no two tuners are the same so it's hard to give an exact answer

1999 formula m6 slp catback loud mouth 1, ls6 intake, slp ram air tune
327 rwhp 343 tq.
