"Great product and sound, really wakes the car and neighbor hood up. Has some pretty bad drone in the car at 2,000 RPM and steady at 50 MPH but for us this is not a daily driver so I love it. I've had people stopping me in parking lots to find out what kind of exhaust I had because they loved the way it sounded. If it's your daily driver, I would go for the 50 series flows instead of the 40 series but if you want to turn heads go for this kit. Also at 60-70 MPH it really quiets out so a long trip isn't a problem unless speed limit is 50 the whole way."

"This is a great product. I didn't know it was just a rear axle back exhaust system. Regardless, great high quality product."

"After searching the web CarID had about the best prices that I could find for the exhaust system that I needed for my 2010 Dodge Charger. I installed the system myself and if you have some experience on cars it shouldn't be too hard for you to do as well. The sound that the exhaust produces is just enough to give you that nice little rubble, and it's not too overly loud inside the car. The only thing that I didn't like about the purchase was that Canada Customs charged me an additional $152.00 USD to clear Customs. That is to be expected cause Customs always wants their share too. I will be back shopping at CarID again soon for a set of rims as they also have a hugh sellection to choose from."

"it took me about 3 or so hours to completely remove the factory exhaust and install this kit on my 2010 tacoma. however this was also the first exhaust anything i have ever done. the instructions were easy to follow however and explained every step in clear detail. kit sounds amazing especially when you upgrade the intake like i did. truck sounds like a Hoss now even with it being just a V6 4.0 liter engine. ;)"

"2011 2500hd product fits good with a little adjusting the exhaust goes right on the factory hangers. Nice deep tone but doesn't drone in the cab during cruising."

"I've installed this kit by myself and it was easy. Flowmaster knows how to do it right. 2.5 hours only because I like to get it just right. The sound is just what I wanted."

"This system is of high quality and easy to install. I was very impressed with the fit and it came with all the required hangers. The sound is fairly quiet for dual exhaust which is nice. No need to wake up the neighbors."
