Back in 2010 when I got my 2010 GT I put on the Roush axle back exhaust system and the drone at 2000 rpm drove me crazy and I removed them and put on a pair of Magnaflows which have been very good. (I had posted YouTube videos showing the differnece between the Roush and Magnaflows from inside the car.) I was happy with the Roush's outside noise level but the drone was too much.

Now recently I have heard about the MRT Interceptors which suppose to get rid of the dreaded drone at 2000 rpm. I was wondering if anyone has any data regarding the loudnest of the MRTs vs the Roush? If it is not too loud I would love to put on the MRT Interceptors and sell the Maganflows. Any input?

I can't speak about the Magnaflows or MRTs, but the Roush off road mufflers which are aka Borla Stingers have been replaced with the Roush extreme mufflers. This eliminates the 1800-2000 RPM drone.
