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.
