"Just installed it a few days ago along with a Volant cold air intake, swapped out my K&N intake and MagnaFlow exhaust (had those in for 5 years), haven't noticed a change in mpg yet, but sure does sound better and power to the wheels feels stronger...Highly recommend."

"This is an excellent product. If you have a ramp or hoist it makes the installation much easier particularly for removing the original exhaust system. The quality is first class and everything fits as it should leaving a professional factory fitted appearance to the vehicle. I used pot belly black paint on the portion that crosses the rear of the diff. I live in Australia so it had to be right first time. It is."

"I started with BBK cold air intake and long tube headers and this exhaust system completed the awesome muscle car sound/additional horse power I was looking for. It's a bit expensive but you get what you pay for."

"I had a local muffler shop install the system. They had no problems, and their install price was reasonable. At first, I was somewhat disappointed in the system, as I expected the exhaust note to change dramaticallly, and it did not. However, after a rather lengthy (to me) burn in period, it did change. I was suprised at the time required for the system to "burn in". I did not make any long trips, and it took several shorter "in town" runs for the "burnt smell" to go away and the exhaust note to noticablly change. So far, I'm quite satisfied with the system."

"Best exhaust system ever! I had a Gibson exhaust system before this and it rusted within 2-3 years. Borla gives you a 1000000 mile warranty and its made of stainless steel which never rusts and its worth every penny. I love how much more power it gives the truck and it sounds incredible!"
