The best sounding muffler to replace all overpriced glass packs that have terrible interior resonance or droning on the market.

The muffler you've been waiting for! A 100%-flow performance muffler that won't make your ears bleed. The Dr. Gas RevPro Muffler comes in small case (4-cylinder/6-cylinder) and large case (6-cylinder/8-cylinder).

Our Dr. Gas RevPro mufflers use our patented spin-trap design to give you an extremely smooth, deep-toned exhaust note with no rasp and excellent performance.  Our Dr. Gas RevPro mufflers flow equal to a piece of straight pipe!  It's true.

Plus, our mufflers are tough!  They're constructed from thick-gauge aluminized mild steel, then painted with high-temperature muffler paint.  Would you dare drive your truck over one of our competitor's mufflers?
