Doug Thorley Dual Exit Exhaust for 95 GMC Sierra

Posted on 10/18/2007 by David P. - 1995 GMC Sierra (Felton,CA)

3 of 5 people found the following review helpful.

"Overall I'm very happy with the product I received. The exhaust looks great and sounds even better. It's given my old truck a whole new personality. The one thing I would have liked to have seen them do better is provide more comprehensive installation instructions. Even better would be if AutoAnything could have those instruction on line as a .PDF or something. The instructions I received were as minimal as you can get. The actual installation was not hard to figure out for someone who works on vehicles, but not having good instructions up front to review before tearing apart your vehicle can make one a little nervous."

"This system is actually a Jardine brand that is known for sportbike exhaust systems, under the Doug Thorley name. That aside, its an affordable, straightforward and great performing system. 5 exhaust tips out of 5 :)."
