"I had the exhaust put on at a shop because even though welding isn't required it definately makes everything easier. They only charged me $70.00 and it took about 2 hours. The sound isn't quite as loud as I would have expected, but it definately purrs, and an increase in horsepower is easy to feel. Not sure about gas mileage yet."

"Overall this piece is great. install was easy but the instructions were a bit vague. Also if you have lited your truck as I have you will need to slightly change the fit of the exit pipes and the way the muffler sits. But it i a great sound and still looks good."

"Great product! Big improvement on the stock system. Worth the money. I had a little trouble getting the dual exhaust level but that was purely a cosmetic issue. The clamp are little tough to tighten down but with an extension on the ratchet it tightens much easier."

"ordered the flowmaster exhaust for my "03 durango to replace a rusted dynomax. delighted to say that the cabin "rumble" is reduced with the flowmaster over the old dynomax system. overall exhaust sound is quieter than the dynomax but still turns a few heads. easy to install."

"I drive a 2006 Ford F-150 super cab. The install took about an hour and a half or less! It was pretty simple. The sound is nice and deep, but if your looking for extreme volume, this ain't it! My neighbors now when I'm home, but don't hate me! I installed this kit w/ a K&N cold air intake one night. Truck sounds and drives nicely! I noticed alittle more power. I added a Hypertech performance programmer the next day....SWEET!!!!"

Flowmaster Ehxaust - American Thunder

Posted on 12/05/2007 by Ryan T. W. - 2006 GMC Sierra (Kanata,ON)

"I recently purchased the American Thunder Exhaust from Auto Anything - Excellent service and price. The exhaust was installed on my 06 GMC Crew Cab. The installtion was fairly easy and the system seemed to fit together nicely. One of the dual exits is very close to my spare tire so I may have to do some adjusting to keep the spare on the truck. I did notice a little more mid-range power but the sound is not as loud as I would have hoped for."
