exhaust for 2002 Mustang GT

I was wondering if anyone had any suggestions. I want to install flowmasters on my mustang but not sure what series to go with. The 40 series or 50 series. Any help is greatly appreciated. Thanks

Performance gains wil be similar across most performance brands. Really depends on how loud and the type of tone you are looking for. Check out mustangexhaust.com http://64.177.72.121/forums/index.php. They have audio clips of various brands.

I prefer 40 series over the 50's. If you want a REALY nice rumber go Super 40's. If you want a toned down rumble but still with a nice bark, go Delta Flow 40's (step under the Super 40's)
