Hey, Hows the performance gain with a DG national pipe and an FMF power core silencer? How does it compare to FMF Fatty and Paul Turner? Thanks

 

IMO... i had dg pipe and silencer first after stock.... nice performance gain. then i had fmf fgold series fatty and silencer.... still nice over stock ...(slight problem with double igniting or some crap after being warm) Now i have paul turner national kit on motor with matching exhaust no more double pinging or igniting.... just my fact on my setup.
