Exhaust Sport Headers.

Performance headers improve exhaust flow and sports car sound; Sport Headers include 200-cell HJS Sport Catalytic Converters.

SOUND:
These headers will give you a significant volume increase and give your 911 a stronger flat 6 wail.

POWER:
Headers are often the most effective way to improve power on your naturally aspirated car and these sport headers are no exception. On our dynojet we saw gains of 8 whp and 14 ft/lbs of tq at 3000 RPM, 13 whp and 16 ft/lbs of tq at 4400RPM, and holds those gains all the way to redline.

FEATURES:
Fits all Porsche 997.2 Carrera vehicles 2009-2011
• Improves power by 13 whp and 16 ft-lbs. of torque at 4500rpm
• Saves 4 lbs from the rear of the vehicle
• Includes multi-layer exhaust manifold gasket
• Includes German-imported 200-cell HJS Sport Catalytic Converters for maximum performance
• Investment-cast high-velocity 3-into-1 merge collectors for maximum performance
• Constructed from high-quality 14-16 gauge C.N.C. mandrel-bent T304L stainless steel for optimum flow and maximum durability
• Direct bolt-on replacement for the restrictive OEM headers
• Backed by the Fabspeed Lifetime Warranty

INSTALLATION NOTE:
To ensure proper header seal, after initial heat cycle, tighten all exhaust bolts to the OEM torque specs.

DISCLAIMER:
This product removes the OEM catalytic converters from the vehicle, and as such, is strictly intended for closed track events and off-road use only. This product contains a High-Flow Sport Catalytic Converter solely intended for track and race cars as it is NOT California Air Resources Board Certified and not EPA certified. You are hereby informed and warned to check your local, state, and federals laws before buying and installing these or any aftermarket parts to be sure whether usage is in violation. All installation-risk and use-risk is borne by the end-user and installer of these parts.

Please note:
This is a special-order item manufactured to order. In some cases, please allow 4 – 5 weeks for the delivery. Special order items cannot be cancelled from this supplier once your order has been placed.

NOTE: Sports catalytic converters and bypass pipes do not have type approval and are not legally permitted for use on vehicles manufactured after 1st March 2001 in the United Kingdom. They are not MOT compliant and must not be used on public roads. These components are intended for race and track use only. If you are located outside the UK, please consult your local laws and regulations to ensure compliance.

Exhaust Sport Headers.


fabspeed

Direct replacement for the restrictive OEM headers, offering improved power and throttle response throughout the RPM range.

Why We Choose HJS Catalytic Converters:

HJS German imported catalytic converters are made from some of the highest grade material you can find in a catalytic converter. This yields high performance gains and longevity so it wont deteriorate over time like lower grade catalytic converters. These catalytic converters flow up to 93-95% of a straight pipe in most applications. The benefit is that you get the "straight pipe sound" while still being able to provide enough emissions scrubbing to prevent a check engine light.

FEATURES:

Fits all Porsche 997.2 GT3 / GT3 RS (2010-2012)
• Includes German-imported HJS 200-Cell Tri-Metallic Sportcats
• Adds 21 whp and 32 ft-lbs of torque greatly increasing throttle response
• Saves 2 lbs from the rear of the vehicle
• CNC mandrel-bent 1pc primary header tubes
• High-velocity motorsports-style merge collector
• Constructed from T304 Stainless Steel
• All Fabspeed performance products are backed by the Fabspeed Lifetime Limited Warranty

DISCLAIMER: Fabspeed's 200-cell high-flow catalytic converters are not C.A.R.B. certified and are for Off-Road Use ONLY in the state of California.

INSTALLATION NOTE: To ensure proper header seal, after initial heat cycle, tighten all exhaust bolts to the OEM torque specs.

NOTE: Sports catalytic converters and bypass pipes do not have type approval and are not legally permitted for use on vehicles manufactured after 1st March 2001 in the United Kingdom. They are not MOT compliant and must not be used on public roads. These components are intended for race and track use only.
