I actually did read cobb's map notes which says TBE but i had also read on here before that you just needed a downpipe for stage 2, so i wanted to make sure. So far the perrin twin tip catback looks the best to me.

This is illegal, annoying as hell to the poor bastards that have to drive next to you, and gives no gains over a half way decent cat-back.

1) It's not annoying...it produces glorious subaru noise...which therefore makes it amazing...and it lets u go stealth as well...which equals steezy as hell

2) well if u wanna go all legal...most turbo backs are illegal as legal limits in most places are between 94 and 96db

and the most important part) i never said it would gain anything i said it helps retain some of that topend power that all the sudden drops off after 5.5K...and i've got the dyno charts to prove it
