The very first place to start increasing the power of your Cobra is the exhaust system. It is critical to the output of the 32-valve engine to scavenge the exhaust effectively and that depends upon the Level of tune and the total flow requirements. Go too big on a Level I or II engine and you will lose torque and mid range. Too small a pipe on a Level III or IV and you will never reach the power potential of the engine. The 4-valve exhaust port on a high flow cylinder head needs at least a 1 7/8" primary and you will not lose torque with it, you will gain torque and power throughout the power band. Our new Level II and III 1 3/4" mid-length header bridges the gap between the SVO shortie and our long tube headers and uses a modified Bassani X-pipe, giving advanced scavenging and flow in an easily installed and affordable package. Horsepower gains are in comparison to a stock system and will increase as the power level goes up. All TMS headers are of the highest quality construction and are hand built. We use 1/2" flanges for leak proof sealing, 14 gauge tubing for rugged durability and ceramic coatings for heat insulation and a lasting appearance. You'll love em!
