I was wanting to upgrade the exhaust on my 03 boxster "s" and i was considering the GHL exhaust in the tweeks catalog, as well as the cone EVO intake. Anyone have any input or experience on these products? The Intake is $400 and the exhaust is on sale for a $1000. Thanks. One more thing, if i do the changes, will I have to have my ECU recalibrated or will it self-adjust?
