Chopping off exhaust. 1980 gs450e

[austens39]

I have questions about modifying my exhaust, but I've heard all this talk about back pressure. What would be the result of cutting the exhaust off just before the baffles where they start to flare out. some people said I would lose powers and others have told me I could gain some. I don't know who to believe. has anyone else done this and seen the results?

cheers

It will lose power, sound like chit, run like chit, and then spend years out leaning on the shed. Leave it alone.

They make nice pipes that will work well on your bike, if you know how to tune it properly.

man I was really hoping for some optimistic input... you guys are realist for sure. thanks for the advice.

He's right. Leave it alone and wrap it with some header wrap for that cool look

When I bought my little 81 250 it had stock header with MAC exhausts.
The crossover chamber was shot so I cut it out and went 2 into 2 with the MAC's.
NO power at all and loud !
I bought a stock exhaust system off ebay, installed it and the difference was immediate.
Much more power/pickup.
A 250 isn't a powerhouse anyway so the difference was amazing.
