Replaces factory catalytic converters with a straight-thru resonated European design for increased flow, resulting in more horsepower and improved throttle response.

SOUND:

Getting rid of the factory catalytic converter will dramatically increase the volume of your exhaust and release more of that signature air-cooled flat 6 sound. A straight through resonator is incorporated into the design so you won't get any of that rasp associated with straight piped cars.

POWER:

An excellent way to increase power on your classic 911. On our DynoJet we saw peak curve gains of 21 whp and 17 ft/lbs of tq at 4500 RPM, and maximum power increases 16 whp and 16 ft/lbs of tq.

FEATURES:

• Fits all Porsche 911 SC and Carrera vehicles (1976-1989)
• Adds 16+ whp and 15+ tq and significantly increases throttle response while saving 8 pounds
• Improved sports car sound- gutsy european pre-muffler style
• Includes straight-through resonator with stainless steel wool packing to last
• Includes O2 sensor bung so the fuel injection system can automatically adjust mixture/idle/part throttle for maximum performance
• Constructed from mandrel bent T304L stainless steel
• Simple DIY bolt-on installation, no cutting or welding required
• All Fabspeed performance products are backed by the Fabspeed Lifetime Warranty
