Piper is the loudest. My mate has a turbo back de cat mongoose and it sounds amazing. Although the gooses tail pipes don't sit level which is annoying I think the left hand pipe sits about 1cm further in.



The bang and pops when you dip the clutch blip the throttle at around 2.5-3krpm are mental, Nice little licks of blue flames too

Anyone know how to get them to bang and spit flames while free reving while sitting still.
