This thread has mixed feelings about performance and customer satisfaction.

I chose the Magnaflow Performance Exhaust MPE, it was cheaper and I have Magnaflow SS mufflers in my LT1 and I'm happy with them.

There is a line I always say and please remember it, "There is nothing bolt-on"

The system's O2 sensor plug may fits the automatic Vettes but, on the manuals it hits the clutch cylinder and it had to be relocated.

Not Centered, fixed later.

The system produces an enormous amount of drone. I found out that the inner bracket was touching the pipe on the passenger side. The MPE is 3" in diameter but, the OEM is 2.75". I cut it off.

The system comes without heat shields and the amount of heat in the leg area sucked. Heat wrap helped out.

While I was wrapping I noticed something disturbing. The Magnaflow resonator something I used to refer as the reXonator is not a true dual resonator.

I decided to eliminate the resonator and replace it with two straight pipes. The system already comes with a "X" pipe.

Re-installed it and a lot of drone is now gone.

If I had to do it again, I would buy Corsas (no drone) or just buy the mufflers and get a shop to build you a "X" pipe and custom piping. Dynomax Turbo Mufflers have no drone but, I don't like the stock look.

Nice exhaust work.
