  • I think i bought the wrong exhaust... Drd sounds so much better than my trinity

  • @vansown747 DRD does sound great... just keep in mind the header broke in half at their non-penetrated weld after this video was taken ( only took a few rides) Had local friend/welder re-weld it.. no problems since!

  • @BVCRacingcom how many hours did you use the pipe before it broke?

  • @vansown747 im going to say honestly only around 5 hours.... i was not happy, Could have got replacement from them, but wanted it to be welded right this time.

  • IS YOUR SPARK ARRESTER OUT

  • @MountainDewKids99  yes it is
