Hey guys I i was wondering if the 01-03 1000 headers will fit on a 03 750 engine by chance, asnd if so what are the benefits and all. thanks alot

Yes it will bolt up and the main benefit is weight.

Yea they'll fit, just kiss your torque and low end good bye

How do you know this?? Can you please explain..... better You gotta explain this one:shifty

It would most likely depend on your muffler and the baffles inside weather or not they are providing back pressure...then again I heard most your backpressure is coming from where all 4 join.

Exhaust systems are tuned for specific engines, to put torque at a specific RPM. This is all controlled by a combination of header pipe length and diameter, up to the collector point. The larger diameter pipes of a 1000 will have the effect of moving the optimum RPM for scavenging upwards, increasing upper end horsepower at the cost of lower end torque. This is the case with most aftermarket full systems. Given that the stock 1000 exhaust system relies on the SET valve to retain lower end torque to begin with, it could have a significant effect on a 750.

thanks guys for your input, and i understand that it wil take away from my low end and torque, but i also have the bike with a +3 rear sprocket, would that help the adverse effects?

I guess it should. Hard to say if the torque loss will be significant or not. There have been other people that have done this exhaust swap, and I guess it worked for them. Like Audi1031 said, the main benefit is weight reduction.

Yeah^^^^ What he said... Besides that, I did it and I felt a loss of low end, enough to pull it and sell it. The weight savings of roughly 8lbs, isnt enough for me to keep it and lose the torque.

Well there we have it. Always best to know from those who've tried it.
