Soul Performance Street Headers – 718 Porsche GT4, GTS 4.0 & Boxster Spyder Compatible with 2020–2026 Porsche 718 Boxster GTS 4.0, Cayman GTS 4.0, GT4 & Boxster Spyder

⚠️ Made to order — please allow 4–6 weeks for production. In some cases, select systems may be available sooner.

The factory 718 GT4 headers were designed to be easy and cheap to manufacture while conforming to strict emissions standards — the result is pressed flanges, squashed primary tubing, subpar collectors, and dense catalytic converters that collectively rob your high-performance Porsche of the sound and performance it deserves. Soul Performance's Street Headers replace every one of those compromises with a purpose-built performance solution featuring cast head flanges, smooth-radius large-diameter bends, optimized collectors with merge spikes, and premium HJS HD 200-cell catalytic converters — delivering increased flow, better response, more power, and a more aggressive exhaust note without a check engine light.

HJS HD 200-Cell Catalysts Soul Performance uses HJS HD 200-cell catalytic converters — the finest performance catalysts available. Efficient enough to meet strict Euro 4 emission standards while delivering a meaningful increase in exhaust flow, the HD design features premium triple-foil winding for maximum strength and a brazing stripe that prevents the core from moving or sustaining damage under sustained high-horsepower use. No check engine lights, no compromises in catalyst sizing.

Construction & Quality Soul Performance assembles each set in-house at their Willow Grove, PA facility from mandrel-bent T304L .065" thick-wall stainless steel. Cast head flanges allow for a smooth transition from the exhaust ports into the runners. Back-purged TIG welding using ARCAL™ Prime argon gas ensures proper weld penetration and long-term durability — crucial for track use. Water jet cut exhaust flanges are manufactured to ISO 9001:2015 standards with tolerances of +/- 0.003 inches for extreme precision. Thick-gauge aluminum fixtures are used during fabrication to prevent warping and guarantee perfect fitment. Every set is rigorously quality-checked and foam-packed for safe delivery. New high-grade hardware and OEM three-bolt gaskets are included for installation.

Warranty

Porsche Parts Warranty Information — Suncoast Porsche

Understanding your warranty coverage is important. Below is a complete overview of warranty terms for Genuine Porsche OEM parts, aftermarket parts, and closeout items purchased from Suncoast Porsche and SuncoastParts.com.

Warranty Coverage by Product Type

Genuine Porsche OEM Parts — 2-Year Warranty

All Genuine Porsche OEM parts purchased from Suncoast Porsche or SuncoastParts.com come with a 2-year, unlimited mileage, parts-only warranty beginning on the date of purchase.

If your parts are installed at an authorized Porsche Service Center, both parts and labor warranty coverage may apply if the part is deemed defective within the 2-year warranty period. Coverage varies by location — please check with your local Porsche dealer prior to installation to confirm their specific warranty participation, as each Porsche Center is independently owned and operated.

Important warranty notes for online purchases:

Labor, diagnostic, and installation fees are not covered when parts are purchased online from SuncoastParts.com or Suncoast Porsche, unless the parts are installed by an authorized Porsche Service Center
Warranty claims must be processed in person at an authorized Porsche Service Center
Warranty service is honored at any authorized Porsche dealer in the United States, however some dealers may decline warranty claims for parts purchased online or from another dealership — always verify with your local dealer before installation
If a warranty claim is approved and the part was not installed by a Porsche Service Center, installation of the replacement part remains the customer's responsibility
Suncoast Porsche and SuncoastParts.com are not liable for any diagnostic, labor, or installation fees charged by another Porsche Service Center

Aftermarket & Performance Parts

Warranty coverage for aftermarket and performance parts varies by manufacturer. Most carry a 1-year limited warranty. Contact us for specific warranty details on any aftermarket product. Please note that diagnostic time and labor costs for warranty replacements are not covered.

Take-Off & Closeout Parts

All take-off and closeout parts are sold as-is with no warranty and are not eligible for return. Pricing on these items reflects their as-is condition.

What This Warranty Does Not Cover

The following situations and conditions are explicitly excluded from warranty coverage:

Improper Installation or Misuse — Damage resulting from incorrect installation, negligence, unauthorized alteration, or accident. This includes any use in racing, competition, or motorsport applications
Lack of Proper Maintenance — Damage caused by failure to follow the vehicle's recommended Maintenance Schedule, or failure to use the correct fluids, fuel, oil, or lubricants as specified in the Owner's Manual. Proof of proper maintenance is the owner's responsibility — retain all service receipts in case questions arise
Consequential or Economic Losses — Towing fees, rental vehicles, loss of use, loss of time, inconvenience, or any other indirect economic losses
Vehicles Outside the USA & Canada — Parts installed on vehicles registered or primarily operated outside of the United States or Canada are not covered under this warranty

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.

Additional Warranty Terms & Legal Disclaimers

This warranty provides you with specific legal rights. You may also have additional rights that vary by state.

Porsche does not authorize any individual or organization to create additional obligations or liabilities beyond those stated in this warranty. Any implied warranty of merchantability or fitness for a particular purpose is limited in duration to the term of this written warranty. The exclusive remedy under this warranty is the repair or replacement of the defective part.

Suncoast Porsche and SuncoastParts.com shall not be liable for any incidental or consequential damages arising from a breach of this written warranty or any implied warranty.

Some states do not permit limitations on implied warranty duration or the exclusion of incidental or consequential damages — the above limitations may not apply in your state. Additionally, installation of certain parts or accessories may affect your Porsche New Vehicle Warranty. Please consult your authorized Porsche dealer for full terms, or contact us with any questions.
