2.73 rear gears - so base model with auto 9.758 @ 74.93 MPH
2.73 rear gears - base model with exhaust 9.239 @81.19 MPH

Not bad!

bought on ebay for $270 shipped. Had 2 previous owners that both said it was too loud, if anything it sounds like 2 crotch rocket bikes behind when you are at WOT. 30 mins or less to install.

 

thats nice for just a axle back change...

weather conditions about the same on both days?

 

There is no way a muffler delete picked up 5/10ths...there were other factors involved there.

 

Who knows what those new 3.5l engines respond to.
