Cut your muffler/s off. Or just unbolt, and drop them. Guarenteed H.P. haha... and noise. Since that was my goal. Not to mention it had the wrong muffler on it and it was smashed and rusted out... I now get 38mpg at 70mph. instead of 29. Lol
You can burn your exhaust valves from not having enough back-pressure.
