"Flowmaster 17234 Cat Back kit. I was told this kit would only work for 86 to 91 cars, but I was Plesantly suprised how nicely it fit on my 85 TA. It only took about an hour and fit perfectly with the stock Hangers. Nice rumble but not very loud. Should keep my teen out of trouble:-) Rick"

"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

"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."

"I received my order in just a couple of days-right at my doorstep. I didn't try to install myself. A local muffler shop did the install for $75. The exhaust sounds great and looks good. I noticed an immediate improvement in throttle response, but gas mileage seems to be the same. However, BE WARNED, this exhaust is very loud. It does have noticeable drone at low RPM's, and may not be the best for a daily driver."

"As always I received my product very quickly and in very good shape. The only real problem I had was with the kit itself. It really didn't line up correctly. After a few slight mods and a few hours it was installed. You can't beat the sound of Flowmaster and I have notice a slight increase in performance. I really can't tell you about the gas mileage, I haven't keep my foot out of it enough. I would definitely buy flowmaster again and look forward to doing business with Autoanything in the near future."

3 of 3 people found the following review helpful.

"This system is the best bang for the buck when it comes to after-market bolt-on exhaust. The install was a breeze requiring very little wrench-ability. The instructions are a bit vague, but understandable with a little thinking. Total install took me about 45 minutes, including the removal of the old system. Sound was a bit quieter than I'd have liked, but definitely a far cry from the stock system. Also noticed that the response to throttle is much better. I would highly recommend this system to anyone wanting to get away from stock and those that want just a bit more pep to their ride."

"The system arrivedThe system arrived in three days, it was exactly as described. Installation was simple it took approximately an hour and a half including removal of the old system. Not sure on added gas mileage but the power seems good and the sound is great, not too loud but deep enough to add that little extra. The only problem was a missing clamp; Flowmast"

"Installed on my 06 4x4 crew cab. Was very easy to install. I am not a big fan of the clamps they were a little tough to get snugged up enough to hold the pipe in place before you really cranked them down. Also I did not cut off the old system like the instructions said. just removed the passenger side shock and jacked up the frame to let the rear end hang and slide the old system back enough to drop the cat connection and then slide the whole system forward over the axel and on to the ground."

"From the order process, shipping to install this was a great company to work with. ordered the exhuast on a monday on the East Coast and it was delivered on Wed, this shocked me that they got it to me this quick. install went just a quickly, i had a little trouble with getting the old system off tryuing to take it of without cutting it, but when i finaly gave up and cut it like the directions recommended it came right off then the new system went on very easy. It came with all the required clamps and hangers and went right in place. very good dound to the system, i would recommend this sytem to a friend everyday if they ask."
