"I love my exhaust. Got it installed after a long weekend waiting for it. Need to get diff't tips (they're a tad small) but the sound is perfect. not too loud yet not too quiet. i got an increase in my gas mileage (1-2 mpg?) but if you get a heavy foot, you can throw that out the window. couple this with an air intake system and you are in business!"

Dodge Ram Hemi Quad Cab (2005)

Posted on 07/11/2006 by Garrett K. - 2005 Dodge Ram (San Diego,CA)

3 of 3 people found the following review helpful.

"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"

"I put this on my 94 Z28, and I am very pleased. It has a great sound! My roommate and everyone else in my apartment complex definatly knows when i'm coming or going. Also the throttle response and acceleration has increased some. I won't know exactly how much till this weekend, when I go time it at the track again. But all around this is a great system."

Very Pleased

Posted on 06/18/2006 by Timothy S. - 1997 Chevy C/K 1500 (Canton,OH)

"I recieved the exhaust system earlier than expected. I put it on the same night and had to go for a test drive. The sound is great, just what I wanted. There is a litte more throttle response also. The factory exhaust came off a little difficult (9 years old), but there were no problems mounting the flowmaster system. I would recommend this system to all."

05 Tundra Exhaust

Posted on 06/16/2006 by Seth D. - 2005 Toyota Tundra (Southwest City,MO)

1 of 1 people found the following review helpful.

"It's okay. The sound initially is deceiving. I was not happy at first, but I don't know if it's the baffles blowing out or what, but I've noticed it getting a little louder, and I love it. I have had it now for about 2 weeks. Install was extremely easy in my truck, took about 1.5 hours. Sound is starting to get really nice. Power is maybe a little better, but the system is heavy. Atleast twice as heavy as stock. Gas mileage is not any better. Pretty much exactly the same. Overall it's okay and would purchace again, just not up to par on my expectations for power and mileage."

Posted on 05/10/2006 by Travis M. (Menasha,WI)

"Easy install!! took me about 30 min to install new exhaust with only a 15mm socket and ratchet. I wanted to keep the old exhaust in one piece just incase the law didn't like the sound as much as i did. getting the stock exhaust off in one piece took some time and thinking on my part but I ended up jacking up on the receiver hitch to give some room between the axle and bed. if you use the provided clamps you'll probably need to readjust and snug them after some driving, i would recomend welding or smaller self tap screws to keep it together. Crome tips look great exiting in front of rear wheels. AWSOME sound, not sure if it increased fuel economy cause i like the sound too much to drive easy. Might consider heat shield for muffler"
