Yes mine is a 2" pipe all the way back, with a Thrush glasspack. I had a shop bend my downpipe, and make a 45 degree bend for the tailpipe for me. I did all the cutting and fitting myself. Not too bad for a redneck with $45 in parts and a 20 spot to the exhaust shop guy. I just have to get my down pipe shortened a little and I'm good to go. I agree, these inline 6 engines sound awesome with a glasspack and straight pipe.
