Reno 9
Active Member
Hi all,
I decide to increase my exhaust pipe from 2 inch to 2.5 inch for my F7p engine on my renault 9,and that will be from the header till the devil direct without anything in the mid BUT some people told me that will decrease it`s acceleration on the high speed and increase it`s torque in the first and second gear.
SO can any one give me the right advise ?
also my car running with a performance chip and k&n filter.
and thanks for every body.
