What pipe-can combo r u running? and elevation?

Aaen single or Crank Shop twins.
I've had both, still dialing in the twins.
Gotta advance your timing with the twins but you still run around stock 8100-8200
Lost a little on the low end but gained up top...just like most twins do.

Coated Y pipe & stock pipe, With a HPS can. I run this anywhere from 0 to 10,000'.

i run the coated y and stock pipe till something actually makes better on the dyno, been told there are some singles and twins that are actually lossing power for the BB rather than making, by the big players

If you haven't seen this BJ shows what he found on his dyno.

I have an 860 built over at Neil's right now for round two... Gonna try to get some twins to work.

When we tried last time we had a few different singles and nothing made significant gains over stock. Neil had one that was ok but we never fit it in the chassis.
