Fullsac core

(1/1)

FRITZBOB:
Hi again, just pulled mufflers off, notice crossover pipe underneath smashed is that for performance wise and can I switch that out I want to keep my head pipe for warranty’s. Sorry if this has been discussed already.

FLSTFI Dave:
It is not flat like that for performance.  Just the way the factory builds them.  Not sure any body makes an round cross under that works with factory head pipe, and brackets.  Doubt a round one would be any gains with still having the stock motor and headpipe.

Fullsac when you use his head pipe it comes with a round cross under and brackets. 

FRITZBOB:
Got my stock cores out of Mako shark, a lot of restriction. I know for EPA. I would think it should better and cooler :)I’ll get my 2.25 cores today.Can’t wait to too sound them off 4:30 I the morning
To my neighbors. If I were to do it again I’ll just Buy the mufflers right away.I’m just so cheap.
