I'm replacing the centre pipe on my sti hatchback.. I have a prodrive pack,cosworth filter, 7's plugs.. I'm going for a remap,what centre pipe would be best 2.5 standard size? Or 3in?
Would be better if the whole system was 3" as no point going 2.5"-3" then back to 2.5 again so if the rest of the system is 2.5 then just stick with that or replace it all with a 3" system
2.5 inch and worked fine on my hatch to 460bhp. 3 inch is fine but you find the bends on the pipe taper down sometimes rather than being consistent throughout.
