Whats the best street/strip combo for the exhaust? Cats no cats? Back pressure? Whats to big 3inch? 2.75? or leave 2.5 take out cats? X pipe? Please help thanks

As long as you actually have full exhaust on the car, you're going to be ok on back pressure. I'm not exactly sure how big the piping on the 03 cobra is. I know they have bigger tips, but I don't know if the piping itself is any bigger. Past that it's pretty much up to personal opinion. X pipes give you a little more gain and so do uncatted pipes, however, the difference between a catted H and uncatted X really isn't all that huge. Just go for what you think sounds best and the fact that you're getting a freer flowing exhaust than stock will give you just about all the gains that you're gonna get.

What in the hell did you just say? Haha. You just mixed like 10 types of exhaust in there and I'm pretty sure you referred to a prochamber as mufflers. [8D]

I run a MAC O/R H-pipe with a Magnaflow Catback and it sounds nasty as hell.

SLP Loudmouth. As for as the X-pipe with cats or offroad how loud do you want it to be?

Ugh, I can't deal with that. That's just way too freaking loud. We went on a cruise last weekend and one of the guys had that setup on his GT, O/R X and SLP LM I catback. He gunned it past me one time on the highway and I swear I was deaf for 5 minutes. We met about and hour and a half from my house, and on the drive back I was getting tired of hearing my own exhaust and I have chambered mufflers. That just reiterates that the Prochamber is the best midpipe for me. It isn't as loud, but it adds a LOT more tone. The Prochamber just sounds amazing, nothing compares.

bassani x, no cats, borla catback! Sounds mean when it needs to and has a low rumble at idle.
