[mikempower]

Hey Guys I Appreciate The Advice...
I'm Buildin A Prostreet Bike With A Ultima 140"
And I Am Looking For The Most Usable Power

Would You Rec. 2-2 Or 2-1?
I'm Not Worried About Noise

Check out RB Racing or D&D Boarzilla

Use a Corvette exhaust, that'll probably be free flowing enough.
For your build, you might want to drill it out a tad!!!!!!!!!!

RB racing, guppy, burns. or just hang some 2" pipes off of it and keep sawing off an inch at a time till ya get peak power. LOL

really, maybe you should call burns on this one.

You might a need a custom going that big!!! Talk to Dog155 he could probably help you.He runs a 155ci,I think!!

noise is not an issue and build is set to kill.

like claydbal said -

2-1 burns stainless, guppy

2-2 cycle shack 2" tapers with baffles removed
