was louder than I liked so I replaced the muffler with a GM product which reduced down the load tone. overall I had a pickup of speed which was a plus.

I am very pleased with my new Magnaflow Exhaust System! The mandrel bend on the left tail pipe had to be reworked a bit to fit properly. I can tell a significant improvement in power and it is quieter than the previous aftermarket exhaust which I replaced. Sounds a lot better.
