Posted on 05/09/2006 by Daniel M. (Bellingham,WA)

"Looks great on my 95 chev half ton, as well as sounds awesome. I noticed a more power from 2000-3500 rpm, and about one more mpg. I'd recomend this settup for anyone."

Flowmaster American Thunder Exhaust System - Dual Side Exit

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

4 of 4 people found the following review helpful.

"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."

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!"

Flowmaster Review

Posted on 03/30/2006 by Gregg R. - 2004 Dodge Ram (Fort Worth,TX)

"The instructions that came with the system where a little confusing at first. Highly recommend you lay it out to see how the parts should go on. It only took me three hours to replace the entire system; so a novice can do this with a little patience. On the sound, I was expecting more...it does all right while accelerating, but quickly drops off. By the way, it fit on my Ram 1500 1/2 ton with a 5.7L Hemi."

"The kit was complete, they had all the parts to complete the addon. Love the sound. The only thing i will say was that it was a pain to put on, BUT if I had a hoist it would have been much easier. This kit made her firebird a complete new car. Would do it again."
