Lost power

Yo everybody quick question for anyone who knows more than me about exhausts.. (all of you probably), so i've installed the M4 Gp and ended up also using the stage 2 silencer, the bike now sounds f00kin awesome reminds me of the ascari off top gear, BUT due to the silencer reducing the inlet size by atleast 50% will i lose power??? it seemed a bit sluggish upto 150 today (on private roads obviously) whereas with the stock exhaust I overtook a mate and didn't even realise I was doing that speed. Maybe its just because its noisy the pick up in speed is more noticeable. can anyone explain?

cheers

 

I am sure my g.p.r can does loose a little power below 5k but not much. above 5k i cant tell any differance.

Get a pcv and a custom map done, dyno bike in malton would be a good place to go

 

You haven't painted it orange as well by any chance mate have you?

 

Hahaha no why would i have done that?

 

God only knows! Just common knowledge the orange ones are down on power

 

hahahaha very much like ^^^^

 

I just fitted a PCV because my GP style exhaust lost a bit of throttle response and low down torque and I can say it totally sorted it out

 

yes pcv is a must IMHO
even my yoshi felt down in power slightly before fitting one.
worked wonders on my gp-pro

 

how much for a proper setup at a dyno place? also is there much difference between the 3 and the 5 cos the 3 is a lot cheaper

cheers

 

5 can be fine adjusted more and also is more compact.
