Looking for a higher performance exhaust with GT3 Cup sound for your GT4(and 981)? Look no further! The TPC Racing GT4 BLITZKRIEG PIPE KIT is the solution! This kit is essentially an exhaust conversion kit that converts factory GT4 exhaust to use factory GT3/RS center muffler. The factory GT3/RS muffler is an excellent design capable of 500+hp with very little to no restriction as demonstrated by factory GT3/RS cars with 3.8L and 4.0L engine. Our kit includes the conversion side pipes(cat-back) and conversion bracket to make this adaptation possible on GT4, Clubsport and all 981 cars. We have brackets for manual transmission and for PDK. Compatible with factory electronic exhaust sound control. Ideal for use with tuned ECU, race headers, and for bigger displacement engine builds.
A stock GT4 with our BLITZKRIEG GT4 Exhaust Kit paired with the TPC Racing Stage 1 ECU Tune makes over 30whp and 30 lbs/ft of torque! A must for 3.8L , 4.0L and bigger engine builds!
The TPC Racing GT4 BLITZKRIEG Pipe Kit includes:
In-house made aircraft mandrel-bend side pipes
In-house made aircraft mandrel-bend corner pipes with sound control valves (also available without valves)
CNC machined exhaust-to-transmission bracket (available for manual transmission and for PDK)
The following OEM parts are required for the full conversion to use GT3 muffler:

The TPC Racing modified Capristo high performance GT2 system features dual path exhaust to be the ultimate in sound and uncompromised performance controlled as an option by the DSC Sport Controller.
The TPC Racing modified Capristo Exhaust systems are engineered and manufactured utilizing advanced 3D Laser-Scanning, CAD Design, Digital prototyping, and CNC-bending/milling at our factory in Germany. Each system is made of high-grade T309 (1.4828) Stainless Steel and hand polished to a mirror finish. After extensive research, this specific alloy was chosen for its sonic resonance properties, low weight, and durability which are close to the properties of Inconel (used in F1).
SPORTS CATS 200 CELL:
The High Performance Sports Catalytic Converters feature 200 cell per square inch substrate fashioned from the highest quality materials currently available designed to improve air flow for your vehicle and increase performance.
The cell count of a catalytic substrate refers to the number of holes per square inch and is a direct indication of the flow capabilities of that substrate. The lower the count of holes the bigger the hole need to be to fill one square inch, a bigger hole subsequently flows more exhaust gasses.
All of this High flow will not help if the substrate is ‘squeezed’ into to small a diameter can or pipe. For this reason, The TPC Racing modified Capristo Sports Cats come packaged in 5.2 inch packages to maximize exhaust gas flow and operation of the valved exhaust system.
