Anyone running magnaflow cat back?

Do mandrel bends not matter with these engines?

Depends what your comparing them to. The pipes on our rides are pretty good right out of the factory. Your just not going to gain much at all by replacing it.

I do. What year is your truck? I have an 08 5.3L. I did the magnaflow cat back and K&N intake. Together around 20-25 HP. The sound is great. The tip is different, it's oval and has the Magnaflow logo on it. I'll have to get a pic or you.
