What is the difference between the Center Mini Maxflo Exhaust and a center muffler bypass pipe?

The Center Mini Maxflo Exhaust keeps real mufflers in the centre of the car and produces the bigger power gain at 16 horsepower and 22 lb-ft, with a refined dual-tone note. A centre bypass pipe removes the muffler entirely for a deeper, rawer sound and saves 10 lbs against the Mini Maxflo's 5. Choose by how the car is used.

Is it loud enough to be a problem on the street?

No. The Mini Maxflo is the most civil of Fabspeed's centre options for this chassis because it retains genuine muffling; Fabspeed describes the result as a dual-tone sports car note, deep and throaty at idle and through the mid-range. Owners who want the car appreciably louder generally move to a centre or side bypass instead.

Does it keep the Sport Mode button working?

Yes. Fabspeed states the Sport Mode control button is retained when the Mini Maxflo is run with the factory side mufflers, so the car keeps its standard two-stage exhaust behaviour. That is a meaningful difference from stripping the centre section out, and it is why owners who commute in the car tend to land here.

Which exhaust tips are included?

Deluxe Dual Style tips are included in Polished Stainless Steel, Carbon Fiber or Satin Black, selected at checkout, so no separate tip purchase is needed. Spare and replacement tips are sold separately if a finish is changed later. The tips are the same units Fabspeed supplies across its 997.2 GT3 centre systems.

What makes the Mini Maxflo different from an ordinary aftermarket muffler?

The cases are hydro-formed and radius stress relieved rather than folded, then pulse TIG welded, and they are packed with 2000-degree ceramic fiber and stainless steel wool instead of fiberglass, which burns out. Tubing is 14-16 gauge CNC mandrel-bent T304L stainless, a low-carbon grade selected to resist corrosion at the weld zones.

Which Porsche models and years does it fit?

It fits the 2010-2011 Porsche 911 GT3 and 911 GT3 RS built on the 997.2 chassis with the 3.8L flat-six. Fabspeed builds separate Mini Maxflo systems for the 997.1 GT3, the 991 and the 991.2, so confirm the chassis code on the car before ordering rather than going by the model name alone.

Description

Fabspeed Center Mini Maxflo Exhaust for 997.2 Porsche 911 GT3 & GT3 RS

Fabspeed’s Center Mini Maxflo Exhaust for the 997.2 Porsche 911 GT3 and GT3 RS is the rare centre section that asks an owner to give up nothing. Where a bypass pipe trades refinement for volume, the Mini Maxflo keeps real mufflers in the middle of the car and finds its performance through the cases themselves: radius stress-relieved, hydro-formed, pulse TIG welded, and packed with 2000-degree ceramic fiber and stainless steel wool. Fabspeed designs, fabricates and dyno-tests this work in Fort Washington, Pennsylvania, and the numbers reward the effort; 16 horsepower and 22 lb-ft is the largest gain of any centre option Fabspeed builds for this chassis, and it arrives alongside a dual-tone sports car note that is deep and throaty at idle and through the mid-range rather than merely loud. Sport Mode stays live, the tips are part of the package, and the car remains something an owner can drive across a state without regret. For the 997.2 GT3 that gets used rather than stored, this is the sophisticated answer.

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.
