Hello good clevo people.
Im running through my options at the moment with regards to running my car with out the exhaust. Straight out the headers the engine looses a bit of torque so i was considering running some collector extensions. I havent decided what size to go with, either keep the extension the same size as the collector @ 3.5inch or drop the extension down to a 3inch pipe. Has anyone played with collector extensions here. If you have id like to hear about your results.
