Okay guys I just bought a 2007 Mustang and I am looking at replacing the exhaust and I was wondering what the thoughts are between the Magnaflow vs the MRT axle-back exhausts. I use this car as my daily drive (mostly highway) and am looking for a good strong exhaust that won't drown out my radio if I turn it up and give me a decent performance gain. I have also looked at the edelbrock, Steeda, FRPP, and Borla which I think the last 3 are all the same made by Borla. I know exhaust is a tricky question as there are many options but at this point I am mainly interested in axle-back systems that won't require reprogramming the CPU.
