   Have a 2003 Yukon Denali with factory exhaust. The sound of the Factory exhaust sounded fine, but noticed I was getting check engine lights and lower than normal MPG.

   When it came time to replacing the exhaust (I have had a to-do-list of parts to upgrade), I wanted something that would «liven» the engine sound, but not be too much. I browsed Flowmasters website and found the different models based on sound. This model was on the quite end of the spectrum. I took a gamble and purchased this muffler.

   After purchase (and before receiving) I climbed under my Yukon to discover I had two pipes going in to the muffler (I did know that before buying) and one pipe out, but it was like 3 1/2″. I was stressed. Where am I going to find someone who can bend 3 1/2″ or 4″ pipe? If you ask around, I couldn’t find anyone. Made a quick call to Flowmaster to get ideas and they said «this muffler is designed for the 6.0L engine in the Denali and Escalade… it comes with a pre-bent pipe». So by accident I ordered the perfect muffler for my make and model.

   So back to my check engine light and bad MPG. After I installed the muffler and put on a new tip (I purchased a 4″ tip from amazon) I was very impressed with the sound and look of tip, I drove around for 10 miles and no longer had a CEL. Decided to do something unsafe and cut my old muffler in half. I discovered my old muffler was clogged with black junk… causing poor back pressure. Had no clue that mufflers could good bad and affect performances.

   I highly recommend this muffler kit. Made a difference in sound and minor improvements in lower end torque. This muffler isn’t too loud and has «zero» in-cabin drone.

   Installed this muffler on my 2001 GMC 2500HD with a 6.0. I purchased this over the «cat back» system basically because of price. The «system» was double the price just to add a tailpipe with a polished tip. Well as I do not weld nor own a welder I had it installed at my trusty muffler shop for a few $$, but if you can weld installation should be easy enough. The muffler looked good, heavy but light in comparison the the factory muffler. It looked good and upon initial start up I was a little disappointed in the sound, as I thought it would have been just a tad louder. After all its Flowmaster, but after driving a few miles the mellow rumble starts to wear on you. The more I drive it the more I’m glad that its not loud, wife has a Mustang GT with Gibsons and that thing drones horribly.
   So, if you want a loud and nasty exhaust… this isn’t the system for you. But if a mellow rumble is all you are looking for this is the muffler for you.

   This muffler fit my 1998 K3500 with a 7.4L very well. I used some commonly available adapters from the local auto parts store to connect it to the 2.5″ pipe coming from the factory catalytic converters. It is a little shorter than the stock muffler, so it gave me extra room to position it perfectly and make my own hanger for the rear. The muffler is very slim, so it didn’t hang down as far as the stock muffler did. I used a 3.5″ tail pipe that fit the outlet just right. It has a good sound, not much louder than stock, and the performance gains were immediate. Lots more off-the-line power, and an increase in economy.
