Race exhaust system by Sharkwerks

The stock side mufflers on any 991 Carrera S or GTS are somewhat heavy, restrictive and for the ultimate weight saving and uber-aggressive tone only we offer a replacement solution. Not for the feint-hearted but delivering an aggressive racey sound, our "Race Exhaust" saves considerable weight, improves flow and removes heat/hot-sports away from the tire. This system is aggressive and not intended for those looking for a PSE-level sound.

This system removes and replaces both side mufflers. All 991 S / GTS cars come with three mufflers from the factory and with this sytem you retain only the stock center muffler (with PSE as well). It is compatible only with the 3.8L 991 S or GTS (with PSE) models and not compatible with the 3.4L engine for the Carerra. For cars with PSE the valve system on the center muffler is still functional (from loud to louder).

3-D CAD designed with optimal flow, fit, weight savings and sound enhancement, our system replaces the two side mufflers on any Porsche 991 Carrera S (3.8L only at this time), whether or not it has Porsche Sport Exhaust (PSE). By utilizing appropriately-sized diameter tubing and maximizing the length we achieved our desired sound and minimized resonance. Our direct bolt-on installs into the factory location without any modification or compromise and is completely reversible. An overall weight saving of 20 pounds is achieved with a more aggressive idle and outside bark with a deeper tone. On the inside you can expect more exhaust noise at lower RPMs with a more exciting pitch when the gas pedal is stomped on. The two side mufflers do not utilize a straight-through design causing the sound to be more muted than some would like. Expect slightly better performance due to optimized exhaust gas flow. For track-enthusiasts not only will you appreciate the motorsport-like sound but with our exhaust you also remove heat from side mufflers away from rear tires.

The factory OEM vacuum actuated sound valves in the center muffler which open and close under different driving conditions are retained, letting the Porsche's engine growl when you want it to, and keeping it a bit quieter when you need it to.

As with all previous Shark Werks exhausts this system is not only 50-state emissions legal but also does not cause any check engine lights (MIL Codes) as it is designed to continue to operate with the factory catalyst and emissions equipment.

Designed and crafted in Northern California, the Shark Werks exhaust utilizes stainless- 18 gauge T304 tungsten inert gas welded stainless steel with mandrel bends and factory equivalent hardware.

Features:
- Designed in-house and manufactured in Northern California
- Improved, more aggressive sporty sound (see video above)
- Does not interfere with SMOG emissions and 50 state legal
- Factory headers, catalysts side mufflers and valves retained
- 3-D CAD designed factory fit direct bolt-on replacing factory side exhausts
- Compatible with either the stock or aftermarket tips
- Use your “exhaust” button to divert routing to switch from flowing through the center to a direct “bypassed” flow
- Real 20 pound weight savings (stock muffler weighs 25 pounds each total) from the rear of the car.
- Long-tube design for sound
- Remove heat away from the rear tires at the track
- 18 gauge T304 tungsten inert gas welded stainless steel mandrel-bent C.N.C construction for durability and flow.

How to Obtain Warranty Service

Installed by an Authorized Porsche Dealer

If your parts were originally installed by an authorized Porsche dealer, warranty repairs may be performed by that same dealer or any other authorized Porsche Service Center in the United States. Please allow a reasonable timeframe for repairs after delivering your vehicle to the dealership.

Installed by an Independent Repair Shop

Please be aware: All warranty claims must be inspected, performed, and documented by factory-trained Porsche technicians at an authorized Porsche dealership. Work performed at an independent repair shop does not qualify for warranty consideration. If warranty coverage is a priority, we strongly recommend having your parts installed at an authorized Porsche Service Center.

Documentation Requirements for Warranty Claims

To process a warranty claim, the servicing Porsche dealer will require:

Your original sales receipt or order confirmation from SuncoastParts.com or Suncoast Porsche
A completed warranty certificate
Proof of proper vehicle maintenance history (if applicable)

Suncoast Porsche retains sales records on file for two years. If you need a copy of your receipt, contact us and we will provide it promptly.
