While I've installed exhaust systems before, I elected to have a shop install this system. (lack of time) The system went on easily (I watched) with no problems. The fit was perfect. Combined with the Banks Ram Air Intake System which I installed myself the same weekend I've noticed a quicker turbo spool up and a 100-200 degree drop in EGT while pulling a 6000 lb. trailer in the mountains. All good. I don't have enough miles on it to accurately determine MPG benefits yet but it seems a bit better. Time will tell as I accumulate more miles on the system.

The system is good quality, but over priced for bent tubing. What disappoints me the most is no noticable improvement in fuel economy, certainly not the 1-1/2 to 2 mpg that the sales tech suggested. I do like the looks of the polished 4 inch tip but hardly worth $500...
