after market -- dyno tuned and all those good THINGS
that's a lot more hot air being let out of that THING
recommend -- ride it just like that for a while
remember if over drilled -- you may end up with toast for piston
this is why for true performance -- after market mufflers are great
dyno tuned and all those good THINGS
