Porsche 996 TT / GT2 SpeedTech Hi-Flow 100 Cell Catalytic Converters
- In stock, ready to ship
- Backordered, shipping soon
Our 100 Cell Hi-Flow catalytic converters were 100% designed by SpeedTech and manufactured "in house". The turbo flanges are bored, ported and flow matched to the 996TT K-Series turbos for maximum performance and improved spool. These are not "off the shelf" universal cats or cheap import converters, but rather high quality substrates manufactured in the USA. Fit all X-cellerator systems. 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.
