"I have a 2001 Dodge Ram Sport Off Road and the flowmaster dual exhaust kit looks and sounds great. It doesn't have the annoying sound of the 40 series muffler does. Overall its a great kit, i had mine welded for better sound and strength."

Great product Great place to order!

Posted on 10/18/2006 by Remzi E. (Ringwood,NJ)

"I ordered this item on Monday and received this on Wednesday. What a great turnaround plus a bid 10% off at checkout!! Thanks I am not that car savvy but managed to do this without an issue. I took my time to save the old muffler for a rainy day (don’t know why) but after I finally got that off it was pretty easy to figure out the install. I put this together within a couple hours and aside from being nervous about it shaking loose from the couplers, the directions and parts fit great. I had one hanger that hits the drivers side springs so I may have to hack off a half inch to keep it from knocking, this is also where people complain about the rubber provided being too weak. I will most likely get this welded or at least tacked together so I don’t lose any parts with vibrations. The sound really impressed me upon startup - LOUD. However once everything is warmed up it could be louder - but that’s just my preference. It seems most of the good volumes are at 3000+ RPMs on the F150. Overall great place to buy, and item pretty easy to install, product worth the bucks."

Pipes Short & Small, but good

Posted on 10/17/2006 by Summer D. (Canyon Lake,TX)

"The pipes were shorter and smaller than expected for Flowmasters. It sounds pretty good also. I think it could sound a little louder. The performance is wonderful. I could tell an immediate difference. All in all, it's pretty good."

02 Dodge Durango 4.7L--Great performance & sound

Posted on 10/05/2006 by Adam M. (Duvall,WA)

"I decided to go with the Flowmaster SUV exhaust for two main reasons. I wanted more performance and a better than stock sound. After installation, I noticed a great V8 "rumble" when the truck is fired up and a burst of speed when the pedal is gunned. I also installed an Air Raid CAI to increase air flow. This exhaust is perfect for those that want a good sounding exhaust (and great performance) but don't want a loud hot rod sound. I went with Autoanything.com because they had the best price (and free shipping) and it was delivered in like 3 days."

Not Everything I Expected On Lightning

Posted on 10/04/2006 by Michael J. - 2002 Ford F150 (Clarksville,TN)

"Looks, this bad boy looks amazing on the truck. Decent sound not as deep as one might think on a lightning should get the delta 40 muffler if you want hella loud. No performance gain +19hp well you can't tell."

Awesome Purchase

Posted on 10/03/2006 by Kenneth B. (Cincinnati,OH)

"Amazingly fast shipping. I had this item with in 48 hours on my door step from the time I clicked process order. This exhaust was easier to install on my Trans Am then it was to remove the stock one. For someone without any motor skills (like myself) the install was very easy and I had it all on and secure with in 30 mins. The sound and performance increase was very cool as well."

Great System

Posted on 09/13/2006 by Chris K. (Belchertown,MA)

"This exaust is the best I have bought for any of the trucks I have owned. The sound and looks are great. Every party was a perfect fit and the system took less than 30 minutes to install once the old system was removed. If you are looking for a great exaust for your vehicle, this is the one."

easy

Posted on 08/01/2006 by Ellen W. (Bucksport,ME)

"my son & i put this on in less than an hour (after taking what was left of the old exhaust!) it was really easy. i'd been almost a year w/out my pipes & tips so it was a big difference! it's a lot quieter-especially in the cab (i can actually hear the radio & have a conversation w/the people in the back now) but it still sounds mean. it's more mellow. still getting used to it but am satisfied."

Nice addition

Posted on 08/01/2006 by Erik B. (Shelbyville,KY)

"The best thing about this system is the ease of installation. Much easier with the use of a lift of course. This system adds a nice low-tone rumble but not enough noise to anger the neighbors in the middle of the night. I do wish the tips were a bit larger or beefier in appearance. I would purchase this product again. Thanks to AutoAnything for the fastest shipment I have ever received."

Dodge Ram Hemi Quad Cab (2005)

Posted on 07/11/2006 by Garrett K. (San Diego,CA)

"Good service, great price, quick delivery, SIMPLE installation, and MONSTER sound (think offshore powerboat, or a 600-hp Chevelle). From start to finish I was able to swap out the stock exhaust for this one in just about an hour. There was no cutting, no welding, I did NOT have to jack up my truck, and the only tool I recall needing for the entire job was a 15mm socket. I used to own a Ford SVT Lightning, so I've always been a fan of the side-exit exhaust. The chrome tips on this system look awesome, and moving the exhaust from the rear definitely cleans up the look of the back of the truck. If you're looking for one of the deepest sounding and most aggressive exhausts available for your truck (like I was) -- then this is your system. However, if you have to drive around with your wife or kids a lot, or care about waking your neighbors everytime you start your truck, then this probably is NOT the system for you. However, I would buy it again in a second. I have no idea how it affected my gas mileage, and really don't care. Although you will have to turn your radio up a bit to hear it over the exhaust, I've actually found myself turning the radio DOWN so that I could hear the exhaust (and its already been two weeks!!). -GK San Diego, CA"
