Does the Maxflo Performance Exhaust fit the Porsche 911 Carrera 4 and Carrera 4S?

Yes. The Fabspeed Maxflo Performance Exhaust for 996 Porsche models fits the Carrera, Carrera 4, and Carrera 4S across the 996 platform, spanning both the 3.4-liter and 3.6-liter engines depending on model year. Check the Applications section above for the exact year range for each model.

Do the included Deluxe Quad-Style Tips fit the Carrera 4S?

No. The Deluxe Quad-Style Tips included with the Maxflo system are built for the narrow-body Carrera and GT3 rear valance and do not fit the widebody Carrera 4S. Carrera 4S owners keep their factory tips when installing this system rather than swapping to the included Fabspeed tips.

Will installation require any cutting or welding?

No. Installation is a simple DIY bolt-on job; the Maxflo Performance Exhaust replaces the factory mufflers directly with no cutting, welding, or fabrication needed. Most installers complete the swap with basic hand tools in under an hour, and the system uses the factory mounting points.

What is the Fabspeed Maxflo Performance Exhaust System made from?

The Maxflo Performance Exhaust for 996 Porsche models is constructed from 14 to 16 gauge CNC mandrel-bent T304L stainless steel, the same grade Fabspeed uses across its performance exhaust line. Mandrel bending keeps the tubing's internal diameter consistent through every bend, preserving flow instead of restricting it.

Does the Maxflo Performance Exhaust cause a check engine light or affect emissions?

No. The Maxflo system is a cat-back exhaust that replaces only the mufflers, so the factory catalytic converters stay in place and emissions equipment is unaffected. It will not trigger a check engine light and is a more street-friendly option than Fabspeed's cat-delete or muffler-delete products.

What's the difference between the Maxflo Performance Exhaust and the Muffler Bypass Pipes?

The Maxflo Performance Exhaust keeps a moderate, resonant tone with no interior drone, making it suitable for daily driving. The Muffler Bypass Pipes remove the mufflers entirely for maximum weight savings and a much louder, track-focused sound. Choose Maxflo for a daily driver and the Muffler Bypass Pipes for dedicated track use.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
