RE: Running a exhaust with deleted muffler
Of course it will. The back pressure was designed to go hand in hand with the exhaust straight off the assembly line.. Blow your engine up otherwise. People should just leave there stock bikes alone. Start piddlin, and have nothing but problems from now on in. Biggrin

it will run too hot and be bit of a noise ordinance be violating pretty sure, had a bike in garage where parked came in open was told never come back with it like that. most will tell ya any type of exhaust mod from stock will need to rejet as factory is set lean so then opening it up will get hotter which is not good. once you rejet after a mod she will be good as any other bike.

i basically was doing the same thing for quite awhile. except i slipped sections of 2 1/4" exhaust pipe over the factory pipes. that was purely cosmetic.

i eventually re-jetted cause of the intake and the cams but running without the mufflers didnt hurt it as far as i could tell. it just lost a bit of power.

RE: Running a exhaust with deleted muffler
So the only way i can run it like this is with a rejet but wouldn't it harm the engine even with a rejet ?

if you rejet no it will not harm it after.

Rejetting only adds more fuel to the mixture, it does not change the sound coming from the pipes. The loss of back pressure from removing the muffler allows more air to flow into the engine, in doing that you now must add more fuel to get the proper mixture of air to fuel. This is what rejetting the carb does it richens the amount of fuel into the mix.

Yeah, I had more opinion. But I thought about how best to put it for a few hours before posting the little I did.

the top muffler slips off the bottom one is part of the crossover pipe.
