"The flowmaster exhaust sounds great on my 2003 GMC Denali. The install took about 3 hours, and was done in my driveway. It took a little bit of time to get all of the joints to line up the way I wanted them to. The only problem I ran into was that the exhaust clamp from the muffler to the tailpipe would not clamp down tight enough. By putting an extra couple of washers on the clamp i was able to get it clamped down. Overall it was fairly easy to install and i am very happy with the results. It gives a far more aggressive sound than the stock system. Would definately purchase again." —Scott N from Sherwood, OR bought a Flowmaster Exhaust Systems for a 2003 GMC Yukon, 6.0L V8.
