Hey about 3 months ago I got an exhaust on my truck. As you know the Flowmaster 40 or 50 series is probably the best sounding exhaust on a ram. (opinion lol) but I got a tip from my local mechanic. The patent on the Flowmaster 40 series has run out. Goerlich's exhaust made an exact replica. Seriously..the only difference is one says flowmaster. I have one and everyones first guess is a flowmaster. it sounds identical and ive looked at cut away versions. THEY ARE IDENTICAL. and Goerlich's is half the price. same material....same sound. Just an FYI for you guys lookin for an exhasut system soon. The muffler is the Goerlich Xelerator if you look it up, it will say its an exact replica. www.Goerlichs.com
