How loud is the Supercup Exhaust System compared with the Maxflo?

Significantly louder, and Fabspeed says so on their own page rather than leaving buyers to find out. The Supercup is a straight-through design with no conventional muffling, which brings out the full flat-six snarl. The Maxflo retains genuine mufflers and is the system to choose if the car covers real road miles.

Will it work with my factory mid-section?

Yes. The Supercup fits with the factory mid-section exactly as it comes, and it also pairs with either of Fabspeed's mid-section upgrades for this chassis. That means you can fit it now and change the mid-section later without having to revisit the rear of the car.

Will my factory PSE tips fit?

No. Fabspeed states plainly that factory PSE tips are not compatible with the Supercup system. It is the one compatibility catch on this product and worth checking before you order, particularly if keeping the original tips is part of the plan for the car.

Is it lighter than the factory system?

Yes. Fabspeed describes it as considerably lighter than the factory GT3 rear section, which helps at the back of a car that is sensitive about carrying mass there. They publish no specific figure for this system, so we have not quoted one rather than guess at it.

Does it affect emissions?

No. This is the rear section, and on a 996 GT3 the emissions hardware sits in the mid-section. Fabspeed publishes no off-road restriction for the Supercup, unlike their Competition X-Pipe for the same car, which addresses a different part of the system entirely.

How difficult is the installation?

It is a DIY-grade job at Level-1 install difficulty, with no cutting, no welding and no fabrication required. It bolts to the factory mounting points and comes back off just as easily, so the car can be returned to standard for a sale provided the original rear section has been kept.

Description

Fabspeed Supercup Exhaust System for 996 Porsche 911 GT3

Fabspeed’s Supercup Exhaust System for 996 Porsche 911 GT3 is named after the cars it takes its character from, and it makes no attempt to be anything other than what those cars are. This is a straight-through rear section in complete T304L stainless, fabricated in Fort Washington, Pennsylvania from 14-16 gauge CNC mandrel-bent 2.25-inch tubing, and it exists to cut back pressure and let the flat-six be heard properly. It is lighter than the factory GT3 system and flows considerably better, and it is significantly louder than Fabspeed’s own Maxflo option, which is the comparison that matters when choosing between them. If the goal is the full flat-six snarl on a car that spends real time at circuits, this is the system. If the goal is a car that stays civil on a long road drive, the Maxflo is the honest answer instead.

Notes

Factory PSE tips are not compatible with the Supercup system
This system replaces the rear section only. It does not include or alter the mid-section, which is where the 996 GT3 carries its emissions hardware, and Fabspeed publishes no off-road restriction for it.
It fits with the factory mid-section in place, or with either the Fabspeed Sport Cat X-Pipe (FS.POR.996GT3.SCX) or the Fabspeed Competition X-Pipe (FS.POR.996GT3.CBX)
For a quieter rear section, the Fabspeed Maxflo Performance Exhaust System is the alternative Fabspeed themselves compare this one against
For the largest weight saving at the rear, the Fabspeed Muffler Bypass Pipes (FS.POR.996GT3.MB) remove 50 lbs, though with no muffling at all
For circuits with a sound limit, the Fabspeed Competition Muffler Outlets w/ Adjustable Turndowns (FS.POR.996GT3.CMO) let you aim the exhaust away from the meter, which is worth having with a system this loud
Upstream, the Fabspeed Sport Headers and XperTune Performance Software (FS.POR.996GT3.ET) complete the build

Fabspeed products are expected to ship within one week of order, though timelines are often much quicker

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.
