hi fellas,
i'm contemplating changing my exhaust configuration which is a 2-1-2 into a 2-1 system. how would it change my bike in terms of
i) performance
ii) sound
iii) fuel consumption
bike is a 2004 monster s4r with pc3, open airbox and current pipes are termi slipons.
i've done quite a bit of search on this forum and other forums as well but can't really find answers that explain a 4v condition. only found info on 2v. so appreciate if anyone can give some feedback.
thanks [beer]

"bump"er nobody loves me :( :( :(
I've got no FHE with them, but what I remember hearing is:
2-1 systems tend to be loud, as they don't usually have a large enough muffler.
Usually there's tuning issues with 2-1 systems that result in less power.
thanks for that response speeddog.
"Usually there's tuning issues with 2-1 systems that result in less power."
as long as there's low and mid range i'm happy.
tuning issues even on the dyno? would a good tuner be able to handle that?
cheers.
A good tuner should be able to get it set up on a dyno.
If you can, get a dyno run before you change it, so you can see what you got.
A 2 into 1 system should gain low end power due to the scavenging effect.
Yes it has a chance of being louder due to only having a single mufler.
If possible have your dyno guy tune each cyl individually. You would be surprised at the discrepancies between each map.
thanks guys. really appreciate that. i'll get the dyno guy to do just that.
