  • I just bought a 300C , and am upgrading it this spring. I was wondering how much those cut-outs were and what exhaust you were running.

    Cant decide between SLP Loudmouth 1 or Magnaflow .

    Thanks

  • @saleen8927 They add Horsepower if you have a turbo for sure. I have one on my supra. This guy too.

  • but again, they do sound incredible....I'd put 'em on either way!

  • cutouts usually don't add any horsepower, just sound awesome. It is easier airflow, but an effective exhaust needs some backpressure - cutouts remove backpressure and could possibly even hurt performance.

  • does it add any hp? you would think it would easier air flow?
