I'm looking at one of those myself, did you get one & if so how is it ?

Did you have any jetting issues & was the sound level ok ?

You'll notice a better engine response with the longer can. The engine likes/needs back pressure which a stubby can just doesn't give.
Look at pipewerx too for options.

was just looking at getting a 225mm stubby?

anyone got something like this and notice a significant reduction in engine response?

to be fair im not looking for max performance so i doubt it will be too bad right?

Re: Exhaust System Recommendation

you need a full size exhaust for the SV as the engine needs the back pressure. Stubby exhaust doesn't work well on these engines.

With the manufacturers I've looked at the DB killer is the same one for all the cans, which is what is going to give the back pressure I'd have thought ?

Re: Exhaust System Recommendation

The volume of the can makes a difference too. The DB killer only does so much.

IIRC then standard are a 450MM can, or something like that? you can then run without a baffle if you want without much loss. Stubby cans reduce the engine performance through out the range (engine braking & roll on torque) is what was lost on my bike, before i replaced it with a normal length can.
