hi there
First post here and a newbie too, so ... hello everyone!

I'm Pedro, from Portugal ( ERICEIRA more to be more precise ) and i'm 22. I've a W201 2.5 16v stock and i'm upgrading the suspensions, wheels and brakes before i touch the engine.

For the engine i have an ITB + EFI + CAMS + CARBON AIRBOX system in sight but only for the next year, though, i would like to get a new exhaust system but i don't know what to do so ... my questions is ... is it a good upgrade, to get a costum build exhaust system with mainfolds ( manifolds? i don't know how to write it ) ... if yes, can you teach me the best way to improve 2.5 16v exhaust system?

Best regards

Pedro
