Best CVH exhaust diameter?
Right the exhaust on the car is shit so i'm gonna take it to a company up the road who fabricate good quality s/s exhausts for just about anything. What diameter am i best off going for baring in mind i want to modify the engine quite a bit in the future, are they 2.25" standard? and will this be enough if/when i want more power? N/A CVH btw.
Cheers
