is there any problem in making a exhaust with tube? i have a 04 r6 with devil and when i look inside of the exhaust i see that it is direct.. is there any problem to make a exhaust with just a tube like in motogp?

OKay a couple things:
A) It's gonna be loud as hell
B) You'll get crappy pwoer enhancements because my guess is you won't be spending any money on r&d to find an optimal pipe length.
C) It's gonna be loud as hell
D) You'll get no backpressure to build low end torque. Even though your devil pipe looks hollow, the inner tube is perferated and creates resistance.
E) It's gonna be loud as hell
F) You'll get no heat disappation so the pipe will be rediculouslly hot.
G) It's gonna be loud as hell

Do you notice a trend.

why in motogp they dont use the inner side perfurated?

what is the rpm that you guys go in the break in?

rpm on break in?

on a cold day just crank it in neutral and red line the bitch

that will break her in

HARD AND FAST BABY

(seriously.....im joking)

On my break in I tried (tried i said) to keep it under 7K. But did get up to 10-11K to give her a little exercise from time to time. Its a bike so enjoy it. I cant wait 600 to 1000 miles to have fun.

no one actually knows how much back pressure a moto gp bike is set up to run on. they are all PROTOTYPES! also take off ur muffler and run it w/o if u can stand it for more than 3 minutes w.o ur head exploding from noise let me know. also the bike will run very poorly w/no backpressure

WHAAAT ???? MY BIKE IS WARMING-UP OUTSIDE !!! :roll:
