I had a flowmaster 40 series my friend gave me and it was terrible no matter what vehicle/engine I had on it, I got out ith a headache every time. Not just the loudness, but the frequency. I have a glasspack on my single exhaust now, not a purple hornie, but a different brand. Red Devil or somethin, I know it is Red. It sounds just fine coming out at an angle behind the rear tire.
