Ceramic coating your downpipe is a great way to lower engine bay temps and increase velocity of the exhaust gas. Because the location of the downpipe is very close the intercooler, an uncoated downpipe emits a lot of radient heat up into the intercooler(which you want to keep cool!). By ceramic coating you minimalize the amount of heat that radiates off the downpipe and into the intercooler. The downpipe also runs close to the transmission so the coating keeps the transmission cooler as well.
NOTE: This is a Coating Service, this implies that you send us your downpipe for coating. Images are for display purpose only. Downpipe not included.
