These 200 CPI/5" (130 mm) Hi-Flow catalytic converters are manufactured by SpeedTech. Our turbo flanges are bored, ported and flow matched to the 997.1 Twin Turbo outlets for maximum performance and optimum spool. These are not "off the shelf" universal cats or cheap import converters, but rather high quality substrates manufactured in the USA. Fits all 997.1 Twin Turbo X-cellerator systems.
SpeedTech offers a lifetime warranty against manufacturing defects for the original owner.
Please note that all Speed Technologies exhaust systems can take 2-3 weeks for delivery as they are custom made and all orders can not be cancelled once placed.
