Great Sound!

Posted on 06/28/2006 by Phillip G. (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. (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."

"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"

2005 GMC Sierra

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"

97 Z-71

Posted on 04/18/2006 by Terry O. (Warminster,PA)

"The installation wasn't exactly just a bolt on for my year truck. The O2 sensor was off by approx 1" than OEM so I had to do some cutting on the heat shield to install the sensor. The "Y" pipe didn't have the same bend as the OEM so it rubs on the heat shield and causes a vibration. The hangars that came with the kit did not represent the Flowmaster name, I was a bit suprised there. Once installed, the system looks great and has a nice performance sound. I noticed an increase in HP instantly and expect it in gas mileage as well. The extra work added an extra 2 hours, total job 4 1/2 hours. Overall I am pleased with the system, looks good and sounds good!"
