Great Service / Easy Install

Posted on 10/26/2006 by Richard C. - 2000 GMC Sierra (Sacramento,CA)

"Ordered the Flowmaster exhaust on Monday, they were delivered on Thursday, no charge for shipping. Great service. Installed the exhaust myself in about an hour and a half. It could have been done faster, but I was in no hurry. The hardest part was removing the original exhaust system. This Flowmaster exhaust system sounds really good. My truck is noticeably more responsive too. I recommend this exhaust system and definitely buy it from Auto Anything. Rich in Sacramento, CA"

"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. - 2005 Ford F150 (Ringwood,NJ)

2 of 2 people found the following review helpful.

"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. - 2000 Dodge Ram (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. - 2002 Dodge Durango (Duvall,WA)

3 of 3 people found the following review helpful.

"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

Awesome Purchase

Posted on 10/03/2006 by Kenneth B. - 1986 Pontiac Trans Am (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."

ROAR!!!!

"This baby made my 5.7 Dodge ram roar. Didn't go on as easy as it should have had to take it to Midas and have them expand the inlet pipe before i could get it on. But the rest was a peice of cake. The product gets 5 stars and the service gets 3 stars. Rep ordered wrong part had plans to install on the long weekend but due to the mishap they were unwilling express ship to fix the error. My other orders went smooth just this one ticked me off. but i am happy with my product."

easy

Posted on 08/01/2006 by Ellen W. - 1998 Dodge Ram (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."

"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."
