Installed headers. 2.5in down pipes to 3in y pipe to 3in inlet dual outlet muffler quad tips. Sounds fantastic

Cool! Why does it look like the floor is cut up in the picture of the headers?

It's just the way the carpet looks it sits over the factory carpet I didn't cut it exact

What headers did you buy to fit in the AWD?

I am very interested in finding out where you got your headers. I need to replace mine and am not able to find any anywhere.

Hi guys. I would like to get input on a couple of exhaust issues.

First, what would prevent us from finding a a pair of used V8 headers, and cutting off the appropriate down pipe, and welding up the opening to the collector?

Second, i have heard different views on what is the appropriate exhaust system pipe size for better performance/fuel mileage vs torque. Can you guys give me some input on this?
