"This was a birthday present for my grandson, and he is extremely pleased with the unit. The hardware came in as promised (shipped one day, delivered the next). The unit was installed by an exhaust system service shop in one hour without any difficulty whatever at a cost of $50.00 for the one hour task. The quality and appearance are excellent. The sound is as grandson said it would be, noticeable but not excessively loud, actually a very pleasant "mild rasp". He is very happy with his birthday present. Thank you very much for the prompt delivery."

"The Magnaflow system was very easy to work with. The instructions were clear, the install was fast and easy. There is no question of the high quality to the product. I liked the low rumble to the engine when it was at idle, however when accelerator applied, the system was overly loud and to aggressive for my taste. I was going for a low rumble and quiet exhaust system. "

"The hardest part of the installation was getting the stock exhaust off - once that was complete, the new one went on perfectly. It fits great, looks great, sounds great and has definitely made a performance improvement. Highly recommended!"

"It took my mechanics less than an hour to install this exhaust system on my '06 Mountaineer. Looks good, sounds healthy at low speeds. When the 4.6 cammer v8 gets up in the revs, as in a passing situation, it really sounds good. Not too loud, though, as my wife didn't even notice! I just hope the stainless holds up."

"I could not have been any happier with the ease of installation. As a driveway mechanic I was able to install this muffler system in under an hour with nothing more than a ratchet & socket. What a complete surprise. I love the sound and look forward to the performance."

"Great customer service and great product! This exhaust was very easy to install, the hard part was getting all the old pieces off. Most of the pieces that they want you to reuse we had to buy because they were so rusted. Overall though the exhaust is a great addition to my Tundra! Sounds really good but not over obnoxious. I am now getting an extra 1 to 2 miles per gallon."
