I bought a flowmaster 80 series today for 100 dollars. I talked to a few people about it, and they said not to use it for that price, they recommended a muffler called V Force. It was only 70 dollars. NICE DEAL!! anyways, I put the flowmaster on, and listened and drove a little, and put V force on, listened and drove a little. I went with the V Force!!! Very great deal and I highly recommend. I used the stock set up and just replaced the muffler, and deleted the cat.

So save some money and buy these bad boys. They are the basically the same design as flowmaster, its just the muffler is not painted.

 

I bought my car with one of these on it. Sounded good outside the car, but the interior drone was just a little too much for me. Just took mine off this past weekend in favor for a stainless Magnaflow system. Good buy though, because with Flowmaster, you pay the extra 30 bucks for the name.
