Dynomax Exhaust Reviews 

Their warranty is vague and misleading... Even their phone support people dont know the specifics. When I bought the exhaust system, I shopped their web site and saw that it had a Lifetime Warranty... Advertised with a big "Limited Lifetime Warranty" Badge on the page for my truck's system. Little did I (or their own phone support people) know that it was only for the muffler and that in just a few short years, the exhaust tail pipe would rust and fall off. More recently, I called and their phone support people said it carried a lifetime warranty. I was instructed to submit a warranty claim online. I did so. Becasue of Covid, the warranty department was closed. I finally received a response over a month later that only the muffler carried a lifetime warranty.

Learn from my lesson... After a few years, the exhaust system you thought carried a lifetime warranty will be junk. Only the muffler will last... And be warrantied. Youre on your own for the pipes. The system doesnt work too well without them so you'll be buying them again .... if theyre still available.

After trying a wide range of different brands on my Peugeot 206 GTI I finally decided to order a Muffler from dynomax.
I had been looking for exhaust that could eliminate extreeme carcabindrone and still maintain 100% performance of a straight trough exhaust.
I contacted dynomax over mail, and they were very helpfull and recommended a Dynomax super turbo.
I was skeptical at first due to the exhausts internal design, so i oversized the pipe diameter abit just to be sure.
This ended up in being abit of overkill(+cfm500 and i needed only 368 lol), but since it had been shipped across the world i decided to give it a go anyways.
And what a brilliant muffler! Car drone was completeley gone and the sound whilst stil deep and sexy, is abit more discreete. And with no loss of Horsepower at all!
Just amazing!
