Flowmaster Review

Posted on 03/30/2006 by Gregg R. (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."

Posted on 03/12/2006 by Jarod W. (Moore,OK)

"I have gained about 1.5 mpg since putting it on. Great sound with a small increase in hp/torque. I would probably get better gas mileage but I have a lead foot. I would recommend this product. Auto Anything is the #1 place for all your needs... fastest shipping with the lowest prices. You can't beat this site."

Thunder Down Under....

Posted on 03/06/2006 by Shane P. (Poway ,CA )

"This system was recommended by a friend and it was a great recommendation I have to say... I love the sound! It's not too loud and annoying for everyday driving but gives a nice deep growl to the exhaust that makes my car that much more fun to drive. I've noticed a decent increase in power as well, mostly in the mid to high range RPMs while maintaining the off-the-line torque. What else can I say... great product, great sound, great performance. Must reprogram computer to get maximum effect."

Great experience and product

Posted on 02/26/2006 by Terry B. (Sharpsburg,MD)

"My experience ordering from AutoAnything was exceptional. The product arrived within a couple of days and I have already ordered more performance parts for my Nissan Titan. Also, the prices are consistently lower than other companies. The Flowmaster Dual Exhaust has definitely made a significant difference on my truck- better sound, more horsepowere, and improved gas mileage. I would highly recommend this product and AutoAnything to anyone!"

Best Sound Out There

Posted on 02/19/2006 by Paul S. (Jensen Beach,FL)

"The Flowmaster American Thunder catback exhaust system is well known for its amazing sound and high quality. Among the loudest of all catback systems, the American Thunder system has a loyal fanbase of diehard gearheads who wouldn't settle for anything less than the "Flowmaster rumble" for their car. Neither should you."
