"Overall easy install on my Challenger R/T; took two hrs by myself, but that was mostly getting the new factory exhaust off. The separate sections made it easy to piece together and tighten down. Make sure the mufflers are tightened in place forward enought to allow adequate clearance from the rear part of the drive shaft. Great sound, not too annoying whilst just cruising (my biggest concern)."

"I love the sound of flowmasters. Some people say that they droan but I can't say I agree. With a properly sound deadened car, the interior noise is minimal. Make sure you use the rubber isolators or you will experience the dreaded interior droan. Overall it was an easy install and the system looks great. You can't beat the system for the money."

"Really like the looks, and price was very well below other places I researched. Improved performance of my Z28. I got rid of clamps that were hard to get exhaust tight enough to my liking. Sound is great! Little bit of a tight fit going to the three inch system. I highly recommend getting it welded, which I did. Even sounds better. Over all, I am very satified and recommend this product. received the system in two days. Thank you Autoanything, I refer your company to every one I know."

"I love the exhaust system it makes that nice quality flowmaster sound without being too loud. Perfect exhaust for the everyday driver who doesn't want that loud deafening noise everytime they lay on the gas. Only one bad thing is they didn't supply a new clamp for where the old and new exhaust mount together. I ended up just welding where they meet, as well as welding the rest. Awesome Flow!"

"I just installed the American Thunder system on my 2005 Ford F-150 V8 5.4L and am very happy with the results. Installation was a snap the hardest part was getting the old system out and even that wasn't too bad as I was able to get the entire thing out in one piece without cutting. I have noticed a difference in highway milage of about 1MPG on the highway as well as a difference in response. Even with the 40 Muffler it is not too loud with the CATs still on, gives the truck a good modest tone and a good bark when you get on it! No droning at all, good for someone who wants some noise but nothing annoying. Overall Very happy so far.... getting it welded this week."

"I purchased the Flowmaster Dual Exhuast system for my 72 Chevelle. I was looking forward to the rumble of dual exhaust!! Being extremely frugal, I searched all over the internet for the best price. I found the best deal on autoanything.com. Purchase was a breeze and with free shipping made it a no brainer. I had a local car restoration shop install the system as I wasn't using headers with the system. To much fabrication for me. The installer commented on how well the system went together and was of very high quality. Overall, I am extremely happy with Flowmaster and Autoanything.com. I have already recommended both to other car guys!!"

"This is one nice kit. My only complaint is the "cheap" clamps, cannot tighten very much and they break. If you have it welded, this does not matter anyway. I like the sound it makes which is quiet at idle and during easy take-offs, but soon as you put your foot into it, it comes to LIFE! It also helped that I added a CAI at the same time."

After installation of my cold air intake the exhaust sounded even better. I installed it on a lift so it literally took only fifteen min."

"The delivery was prompt & sooner than expected.All parts were packaged securely. The installation went as it should go. I did have to grind & press out two of the studs in the forward flange & replace with new grade 8 hardware. Otherwise everything else installed as planned.The Flowmaster system sounds great & low-end power has increased.The sound is mellow at normal cruising speeds & sounds great when you get on it. Very happy with the Flowmaster system."
