I’m really leaning towards the Magnaflow MPE-16605 cat back kit for the Mustang. After a lengthy talk with a tech at Summit I’ve decided to leave the cat forward system alone for now because what he said made sense to me. He said opening the headers will drop back pressure and defeat some of the horsepower gains that the super charger will give me. This made sense to me since the supercharger is designed to raise the boost.

So, I want something stainless and with resonators instead of actual mufflers. I want loud and I want grumble and the Magnaflow kit will certainly take care of the job for me. At $543.93 this should be one of the first enhancements that I complete on the car.

I was also advised that my Mustang is equipped with a high flow catalytic converter but I’m not sold on that one yet. I need to do some more research but I believe I might just change it to be sure.
