cool thanksstay with 2.25 or you'll lose too much back pressure and your torque will drop. I have the Flowmaster 50 and it's sweet. I used to run the 40 and that one was nice too.
Rustys has good prices on exhaust packages. They use the Flowmaster muffler.
A myth? Well, I installed a flowmaster 40 originally with 2.5 inch pipe. I lost most of my torque on the low end. I went back to 2.25 and got it back. Myth? I think not.no reason to put a bigger pipe unless you have a blower on it.
as far as back pressure and losing torque thats a myth.
