Very Pleased Customer

Reviewed By Carnell J (Atlanta, GA) Reviewed for a 2003 Pontiac Bonneville —9/20/2008 8:59 AM

I was very pleased with this piece; not because it wasn't an expensive piece, but how it was put together and how good the flow design split off into two. I recommend this product to any and all who are building an dual setup.

Stock exhaust was so quiet you had to check the tach to see if it was running. I called Magnaflow and asked if the exhaust system my dealer mentioned was quiet, the answer was "YES." It has the largest muffler we have. When it was installed it was NOT quiet. The only option was to add a resonator. The replacement system was a direct fit no alteration install. The resonator was a custom install that had to be welded in!! Fortunately with the resonator it is quiet but noticeable.

Worth the purchase

Reviewed By Robert L (CATHEDRAL CITY, CA) —4/27/2015 5:20 PM

I've had this convertor for a little over a month now. My old converter broke. I was a little nervous purchasing this because i didnt know if it will pass smog and it did. I had this welded it on it fit perfectly the first thing I notice on my truck was that pressing down on the gas pedal was alot more easier it responded alot more better. And it slightly roars more you can tell and with the Flowmaster already on my truck it sounds more better. Air flow is perfect.
