I have a fresh lovely MS axleback sitting at the house. Thought I wanted to tone down my exhaust and bought it. Currently have OBX hdr, 2.25" hi flo catted flex fitted midpipe, 2.25" ss resonated piping & Magnaflow 5x8 oval muffler with angle cut doublewall tip. It is mostly low rumble and only a bit of rasp over 4k if you hit on it idling. Driving is not dronish on frwy but you definitely know it's there throughout rpm range. Car is sportauto with 95k on it and still will pull 30+ mpg if kept at 70mph or less. Not sure how funneling down the axleback to 2" is gonna sound and affect mpg's. Car is lowered too and have had round muffler before the oval one and would scrape on occassion. I do have a cool shop that could step down the piping and add the 2" flange to bolt it up but still on the fence about even using the MS axleback at this point.
