Review on Enhance Your Vehicle's Sound with Flowmaster 953045 Super 40 Muffler - 3.00 Center IN / 3.00 Center OUT - Aggressive Sound, Black by Andargie Marquez

First of all I love Flowmasters. They're on all my cars. So, my first truck, I figured it wouldn't be a problem. no Apparently that sounds awful despite saying it fits the F350 turbo diesel engine. I thought it was the welds but apparently the muffler can't handle the back pressure. My truck now squeaks very loudly when I accelerate. Undescribed "aggressive" sound.
