Put my 65mm throttle body and o/r x on last night. That thing sounds mean haha. I found out that i have stock mufflers though. I thought i herd the p/o mention that he had put flows on but i guess i heard wrong. What kind of performance numbers do you get out of a cat-back system? Is it worth doing for anything besides sound?

It will sound better but you wont have a noticable difference in HP. You might gain 1 HP.

he will gain a good bit from going to an o/r midpipe... That's worth a lot more power than a catback.

why did you put on a 65mm tb? doesnt that come stock on 96's...?

CarlessAndy

Stock is duel 57mm tb i think thats the same for all 4.6 cobras. Not much hp out of it because its still restricted by the stock intake and the intake plentum needs to be dremeled. But all in good time.
