1996 Polaris Ultra, 680 Triple, PSI Stockblaster Pipes, stock engine other than jetting (PSI needles) and clutching.
Update 2/22/15: Since taking this video one of the pipes has cracked badly and will need replacing. I will try posting video for sound comparison after pipe swap to PSI ModBlaster pipes I have on shelf.
Thanks for the positive comments!
