Hi.

I'm thinking about getting this catback because I want more power but not a lot of sound.

http://www.jegs.com/i/JEGS/555/30406/10002/-1/751866|10249

I have a 2001 auto withVAPauto's 1/2"intake MANIFOLD spacer, 25% ud pulley and cai.

I'mthinking 8 hp at the wheels because of the bolt-ons I already have, should get the most out the exhaust.

I do not want true duals because my 327-read-end automatic needs its precious torque.

I welcome your replies. Thanks!

Im not sure about the hp gain but one think im sure is that, that catback is noo good. Go with flowmaster 40's they sound good.

Go with duals, you wont notice a difference.

i am about to go with a dual set up soon and i was wondering the same thing is it going to rob my automatic of its lowend torque and hp. the set up im planning is a MAC o/r h pipe and 2 pypes mini cats welded into the h pipe followed by GT takeoff exhaust with flowmaster super 40's

Why not just buy an H pipe with the cats already in it??? Currently I'd say you've gained around 12 rwhp with what you've done, and you'll gain another 6 after the exhaust.

And what is HP gain with ebay cai, mac LTsand h pipe with 40s, and SCT xcal. Oh I almost forgotred windshield wipers too...lol!
