Great Sound!

Posted on 06/28/2006 by Phillip G. - 1994 Chevy Camaro (Mississippi State,MS)

"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 Truck 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)

"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."

"I love it, it sounds great and has a nice deep tone to it. Its not too loud where you are waking everyone up and getting annoyed while you drive. It seems like it has added some horse power too. It makes me like driving my car even more."

"now that the system is finallyinstalled the sound is great and performance has improved. Flowmaster needs to update instructions for 2006 f150 super crew. you will need to add instead of cutting off 6" as instructions state"

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"

Flowmaster American Thunder Exhaust System - Dual Side Exit

Posted on 05/06/2006 by Robert L. - 2006 Ford F-150 (Coopersville,MI)

"I ordered this system on Wednesday and it arrived on Friday, that was fast. I opened it up and install it that night. It took about 1 1/2 hours to remove old and install new. The directions were great and everything fit perfectly to my factory mounts, no cutting needed it was perfect. The sound was just what I expected not to quite not to loud and if you can keep your foot out of the gas there is a noticable difference in fuel milage (better). I averaged about 300 miles per tank factory exhaust, now about 345 miles per tank and the performance is better also. Awsome job guys."
