Looking for answers.

This is the x-pipe you need. http://www.uprproducts.com/mustang-o...x-pipe-05.html

Exhaust does not affect the drivetrain warranty.

We don't have emissions testing / laws here in Florida. I'm running that same x-pipe on my 3V GT here in Fort Myers.

Though that theory is flawed cause Flowmaster doesn't offer a dual-in/out original 40 series.

Damn, you sound like me.

I've had
Flowmaster AT w/ stock cats - too quiet
MAC Boomtubes w/stock cats - not bad
Flowmasters w/ Offroad H - sounded terrible
MBRP w/offroad H - TOO LOUD!
MBRP w/ stock cats - not bad (My current setup)

and I agree with Menace, I would do the long tubes only with an offroad mid pipe and the stock mufflers.

Welcome to the forum by the way!
