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:
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.
Get new clamps. Worth the extra money
Get your biggest hammer (I used my one handed sledge
Flare the pipe from the muffler a tiny bit to get the new valved pipes started.
Use ratchet straps in strategic places to pull the valved pipes into position for the clamps.
Electrical and vacuum was easy.
