"The install on these puppies was really simple. You do have to make a few adjustments to get them to fit correctly, but its not a big deal. I gained 2 mpg on my truck with these, and with as much as gas is, they'll pay themselves off by the end of year. The horsepower gains are noticeable, but the sound isn't. You can deffinately tell that they are flowmasters, but they sound more like a greddy from the cab. They arnt so loud as to annoy my neighbors, but they sound a hell of alot better than the stock system."

"I recieved the exhaust in three business days. One of the pipes was slightly damaged in shipping but was easily fixed with a hammer. The install took about 3 1/2 hours with another person helping. I ran into some clearance issues. My aftermarket trailer hitch was in the way, so I had to cut some notches out of it with a torch. And because of the trailer hitch, my spare tire didn't fit exactly where it was sopposed to, but after the exhaust was installed, there was no way the spare was going back up under the truck, so now it is in the bed of the truck. I used the clamps supplied with the kit despite claims that they break easily. I had no problem. I tightened them with a 1/2 inch impact gun, and I had no breaks, and no exhaust leaks. I am a professional mechanic, and I can honestly say that the most difficult part of the install was adjusting everything after it was hung. The clearences between the shock and diffy are tight, so everything has to be absolutely perfect before you tighten things up. And when you start tightening the clamps, things move, so you have to constantly readjust. Keep in mind that I did this on an 03 Chevy Silverado 1/2 ton, extended cab. The install could be much different on another vehicle. But overall, after it's all said and done, I'm very happy with the system. It's not so loud that you'll irritate all your neighbors, but no so quiet that you'll be dissatisfied. It only really gets loud on accelleration. On the freeway, you can still hear it, but it won't give you a headache. I haven't actually attempted to measure a gas milage increase, but I have noticed that a tank of gas lasts a few days longer. I haven't observed a noticable horsepower increase. It's just louder. Overall, I'm happy with the system except for the fact that I have a spare tire taking up space in the bed of my truck."

"GREAT SYSTEM. ALL THE PARTS WERE THERE, IT FIT REALLY WELL, ALMOST PERFECTLY. SOUNDS GREAT WITH THE SERIES 50 AND REALLY HELPS MY LITTLE 4.7 SCOOT BUT WITH COLD AIR AND A SUPERCHIPS UPGRADE. MILEAGE JUMPED BETTER THAN 20% WITH THE NEW PARTS AND THE TRUCK REALLY PERFORMS BRISKLY! LOVE THE SYSTEM!"

"Shipping on this item was great was at my house in about three days. The hardest part was getting the old system off, I had to heat the bolts up glowing red and then impact them off. Other than that it was a breeze. Looks good and sounds great too. Would definitely recommend."

"The flowmaster american thunder kit was the probably the easiest and least expensive system you can get, but the quality is great I had no trouble installing the system. I have a flux core welder at the house, so I mounted the exhaust, clamped the pipes where they needed to be put a few spot welds on and then took it off and finish welded the rest. All of this was done by myself with the truck on the ground thats how easy it was. Sounds great just what I was expecting from flowmaster and I've always liked my pipes exiting before the rear tires. Highly recommend the kit."

"Very easy to install. Less than an hour from cutting off old muffler to crawling out from under truck, Done! Welding a little longer. Great sound and noticeable performance improvment. Sound level, in cab, plesant at freeway speeds.If you want your big block to bark with athourity and back it up with sizzle, this is the system! Looks great too. ."

"Easy to install. The directions were very good. The only issue was that the front muffler clamp had 2 nuts instead of one. When I loosened the first nut and couldn't remove the muffler i finally found the second nut. I added an intake sustem as well and I'm getting 2 to 3 miles per gallon more. I was hoping for dual outlets, one on each side but it turned out to be duals on the same side, not what the picture shows."

"I had to have a local shop make me two adaptors to connect my 2.5" pipes to the 3" inlets of the mufflers, but once that was done it went on without too much trouble. The exhaust is loud but it doesn't resonate in the cab, and throttle response inproved quite a bit."

"I bought this system just before Christmas, on the 22nd, received it on the 26th...Good Job AutoAnything. Now for the Exhaust...If you like loud growling exhausts...this is for you. My 5.3 doesn't know it isn't a Big Block 427 yet. It sure sounds it. I noticed a power gain...well acceleration went up a bit...I assume it is helping the engine exhale much easier. The exhaust burbbles at Idle like an old muscle car, and growls above and to 3000 rpms...Past that, it sounds like a friggin' jet on up to the shift points! At highway speeds (1900 to 2200rpms), interior resonance is high...very high...at 65 mph, on long hikes, it does get old, may even make you sleepy. The drone is so bad, panels buzz moderately. It only does it at said rpms, that I've noticed. At throttle let-off, around 2000 rpm's, it does do a little crackle and popping noise...occasionally. The tips are chrome, I assume and are not that noticeable to most people. I was at a gas station filling up after terrorizing the small town I live in (echoes off buildings down main street). An old man was filling his Silverado, next to mine, I finished and fired that bad boy up and he nearly $h!t his pants...he was startled as it growled to life and echoed under the gas pump overhangs...All I could do was laugh and burn rubber out to the road! The muffler, I should note, was not black as advertised, but I don't care, you don't see it unless you look under the truck a lot. The other thing to note is that on the Chevy system, is how close the mandrel bent pipe comes to the driveshaft...about an inch of clearence. I haven't noticed any rubbing, and I don't suspect there would be, you would have to be off-roading heavily to do that...On the street, you should have nothing to worry about. Passing on the Highway is fun as well, as those tips fire right at passed motorists...They get startled and give dirty looks and sometimes fingers...all the better for me. Install was easy and painless...to bolts come undone and rubber mounts get slipped off, and you ca"

"the system went on fairly easy, but I'm not satisfied with the rear mount for the exhaust. doesn't seem to have enough strength. the drivers side rear mount doesn't sit in the right spot so i have to check it now & again to make sure it's not loose. As for the sound of the exhaust.... It's perfect. Just the right note!!"
