summit or jegs best deal !!!! first you need to know what size front pipes you want to run ! 2 1/4 will work with stock exaust manifold, if you have headers you can fit 2 1/2 front pipes. magnaflow has a web site with part numbers for different size length and pipe size. i went with 028915037 2 high flow cats, 064212278 1 magnaflow resonator, 028917732 2 dynomax super turbos from jegs. 2 1/4 and 3" center pipe works good and sounds great. several different lengths of resonators don't pick the short one or you might not like the sound.
