I have a 2001 gmc sierra 6.0. I was looking into putting a dynomax exhaust on it. Any body have any suggestions whether that is a good brand or not a good brand. THanks

 

From what I read when I was first lookinng innto an exhaust for my truck... I took it for just a slightly better brand than the Summit catback system I bought. Since then I have reinstaled my stock exhaust, then upon my return from Afghanistan I had a Flowmaster clone installed and I am very happy with the results.
