Sorry I only have my iPhone for this. The microphone really doesn’t do justice to how much louder it is. I will say I don’t like the sound just off idle but once the revs are up there it sounds great which is why I really tried to keep the revs up in these videos.

Closed course and private roads and all that.

Install tips:

  1. PB blaster the night before really helped with the bolts but I should have sprayed the pipe joints too. MAP gas heating helped but in the end I had to cut one clamp off with a grinder.

  2. Get new clamps. Worth the extra money

  3. Get your biggest hammer (I used my one handed sledge

  4. Flare the pipe from the muffler a tiny bit to get the new valved pipes started.

  5. Use ratchet straps in strategic places to pull the valved pipes into position for the clamps.

  6. Electrical and vacuum was easy.
