TEGIWA – BMW E9X E90 E92 E93 M3 Decat Down Pipes Primary Cat Delete

As you probably know the primary cats are a huge restriction in the E9X M3 exhaust system. These are designed to simply replace the OE cats and are an easy DIY install as this uses a slip on clamp design.
The kit comes complete with the rear clamps.

Gains are 20 BHP and 20 lb/ft torque. An ECU Remap is required to remove CEL and provides an additional power gain over and above the de-cat pipe.
The OEM front wire gaskets are reuseable so do not need replacing.
Please note: this is designed for off-road/motorsport use only. You will not pass a UK emissions test or police road side check with this installed on the vehicle.
