Headers, x-pipe and axle back get you close to a full aftermarket exhaust. The pipes that are between the x-pipe and the axle back will still be the stock 2.5inch tubing. As far as 3 inch systems go, I think magnaflow has a system and there might a few others out there but I'm not sure.

P.S. MD rocks

lol You don't call it a "header back" exhaust but if that's what you feel like callin' it then by all means, you would have a header back exhaust

You may as well order Headers, H-pipe, axleback. (high flow cats to pass emissions if your state has them!)

I am not a GT driver but a few of my friends have Roush mustangs (one stage1, one stage2, and my lovely woman friend has a stage3 =\) If you are going for sound just get a catback.. If you want full bolt ons I would recommend flowmaster, magnaflow, jba, mac, etc. Just Search it on the forums and you will find exactly what you need/want. Or you can go to steeda.com, roushperformance.com (?), saleen.com, etc. Just look around man

Good luck!

If you want more info, be more specific as to what you want to do :P

PS: Don't quote me on the parts.. for some reason I have had an off day with thinking :P

You don't need a 3" exhaust unless you just want to look like a ricer. This is a 281 c.i. engine. That's absurdly small. The exhaust system it comes with is too big already! Oh and dude, do us all a favor and don't text-message your posts. It's rude. JMO.

LOL I agree. The text message format was kinda hard to understand

Agree a 3" exhaust is not needed on this car unless maybe you're running a huge twin turbo.
