Should I drop the cash on the total system if the only other engine mod's will be air cleaner and chip on my '02 S4?
Hi Strati,i think to really make a full system (larger-diameter header) worth while, you'd want to get a valve-job on the cylinder heads. the idea being to get as much flow in the cylinder heads as the exhaust can handle.
yes sir, that's exactly what i meant. larger vavles/seats for more flow through the head to match the capacity of the larger headers. thanks for clarifying chris. used the wrong term cuz i'm too lazy to type out the correct infoWhat you probably mean is head porting and/or the installation of larger valves and larger valve seats. This is a task to be trusted to tuners with verifiable and proven results.
