"This exhaust system sounds great. Installation was easy. Only problem I had was removing the bolts from Convertor, but that was on my end. Other then that, it all went together easy. I would recommend this system to anyone."

"I was looking for an exhaust that looked good that also made the truck sound good but not loud. The tips are pretty small and the sound is pretty faint... I would have liked bigger tips and a little louder rumble. It still looks good though. I haven't had it long enough to comment on power or fuel consumption changes."

"The system sounds good on my 94 bird (v6) its a little ricey, but as it breaks in, should deepen a bit. I was skeptical about the performance I would notice, I was happily surprised at how noticeable it was! the only problem I had was the clamps, the ones that came with the system, were so stiff they were unusable.. gun/hand tightening wouldn't work, $3 ones from Kragen worked just fine =) overall, BUY THEM! they are worth it =) (just make sure to get other clamps)"

"Went together easy. Hardest part was my factory pipe was out of round right where the connection needed to be made but once I rounded it out all fit well and it sounds and looks great! It has a decent.. not to loud tone.. just what I needed for every day use..the 50 series works well in my opinion. I installed it on a new body style 2007 Chevy extended cab 6' 6 bed pickup..."

"I installed this exhaust system by myself in about 2 hours with the aid of a lift. A dissapointment was when I opened the box my series 40 muffler was Grey not black as advertised. In addition to the exhaust I also installed the VOLANT intake system, so my V8 5.4L Ford F-150 could breathe. Im up about 4.5 MPG more than before, and a more noticeable "gitty up" when I hit the gas, also a decent rumble on the road. I just wish it was a little louder but its good for now. Other than that I am thoroughly satisfied with the way my purchase was handled, thanks autoanything."

"i have installed other brands of exhaust systems on vehicles that i have had in the passed. i had read the reveiws and researched them and they all say on how much power and how much fuel they will save you. they didnt seem to make a big difference. this flowmaster surprised me. i did lose some power on the low end but it does come 2 life when you get on it. and oh yes..... i did gain on gas mileage. went from 13 around town to 15 mpg!!!!!!"

"I ordered this system based on other consumer reviews I saw on various websites. The kit arrived very quickly and in perfect condition. My son and I installed the kit in about 2 hours and everything fit as shown on the instructions. The sound is awsome and the power delivery was noticeibly more linear with a good punch in the mid to hi RPM range. If you keep your driving habits the same you will notice improvement in your fuel mileage. My truck is an 08 F-150 with the 5.4 liter V-8 and I gained 2 mpg on the highway and just over 1 mpg in mixed driving conditions. This kit is great I recommend it for anybody."

My order was shipped very quickly. after installing the system I started my camaro and was very pleased with the sound of the system. I would recommend this system to anyone restoring a classic automobile. I would also recommend ordering this system from autoanything they were very helpful and knowledgeable about the system. The quality and sound of the system is very exellent."

"I have an 06 4dr F150 FX4. I waited until the 3yr/36K mile warrenty was up to make the transition...no one at the dealership could give me a straight answer on if it'd void the warranty. I also have a K&N Cold Air Intake installed. The Exhaust is slightly louder than I anticipated...but sounds friggin Awesome!! If you get the American Thunder...don't expect to sneak off to your favorite fishing spot early in the morning...the wife, girlfriend and neighbors will hear you leave in the morning. I'm sure I'll save gas/get a little more MPG when I get use to it and can keep my foot out of it. For now...I'm just having fun with my new toy...lol. Next mod will be the Edge Programmer and I'll definately shop for it on this site. Ohh, and I had it installed at Mr. Muffler for $125. They did an outstanding job...I was in a hurry when I dropped it off and forgot to ask them to tack it in...when I picked it up I noticed they'd went ahead and tacked it without me having to ask."
