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!
