2.5 is fine - 3" downpipe if you want to... 3" sounds a little on the farty side due to the lack of gas velocity, the latter is adequate and will sound good on anything sub 210hp or so IMHO.

2.5" it tis then. Can i come across any probs having my induction the same size?

From my experience, keep the inlet as large as physically possible, I've seen more gains from improving the inlet than exhaust in total honesty... No shitty corrugated pipe, as large as you can physically do, even if it means engineering a better way... People always forget about the inlet system and just assume banging a k&n on will do the trick.

K&n? *cough* no idea what you mean [FACE WITH TEARS OF JOY]
Was thinking again 63mm (2.5") same size as the turbo inlet and will be ran in stainless tubing, dunno wether to weld it solid or just run silicone joins. Spose here the major thing affected will be ease of fitting
