Does the Cat-Back Exhaust for MK6 Volkswagen GTI require a tune?

No. COBB sells the Cat-Back Exhaust for MK6 Volkswagen GTI as a direct replacement for the factory system and states that no tuning is needed, so it works with the stock calibration or an existing Accessport map, and you can fit it before or after any other tuning.

Can I keep the factory downpipe with this system?

Yes. An adapter in the box tapers the front of the system down to meet the factory downpipe, so nothing further forward has to change, and no cutting or welding of the original pipework is needed for the joint itself.

What does the exhaust sound like on a MK6 GTI?

Expect more of the four cylinder and more turbo noise than the factory system lets through. A single 10 inch COBB stamped muffler keeps it in check, so the result is louder and more characterful while staying civil enough for daily use.

Is it legal to run on an emissions controlled vehicle?

Yes. COBB classifies this part as not emissions related, which means it can be used on emission controlled vehicles. It mounts behind the catalytic converter and leaves the factory emissions hardware in place, so no Executive Order number applies. Local noise rules still apply.

Which GTI model years does part 5V1100 fit?

COBB confirms this cat-back for the 2010 to 2014 USDM Golf GTI and the 2009 to 2013 world market Golf GTI, all on the MK6 chassis. Manual and DSG cars are both listed. The 2015 and later MK7 GTI takes a different COBB system.

How much weight does it save over the factory exhaust?

COBB quotes a saving of 5.5 lbs compared with the factory cat-back. It is a modest figure that comes off the very rear of the car, and it arrives alongside the sound and appearance changes that most MK6 owners buy this system for.

COBB Tuning Cat-Back Exhaust for MK6 Volkswagen GTI

COBB Tuning’s Exhaust for MK6 Volkswagen GTI swaps the restrictive factory cat-back for 304 stainless steel tubing that runs 3 inch from the front before dividing into dual 2.5 inch sections, finished at the rear by dual-walled 4 inch tips carrying the COBB logo. On the 2010 to 2014 USDM GTI, and world market cars from 2009, it is a sensible first modification for an owner who wants a richer note, since it bolts on with no tuning and shaves 5.5 lbs from the stock system. Owners chasing real horsepower should budget for an Accessport and supporting parts too.

Design and Sound

COBB wanted more engine resonance and turbo whistle without making a daily driven hatchback tiresome on the highway. A single 10 inch COBB stamped muffler does that job, sitting in the stainless run between the 3 inch front section and the twin 2.5 inch pipes that feed the tips. Up front, an included adapter narrows the Exhaust for MK6 Volkswagen GTI so it mates to the factory downpipe, keeping the job a straight swap.

About COBB Tuning

COBB Tuning was founded by Trey Cobb in 1999 in Rockwall, Texas, as a Subaru performance shop in the back of his father’s tire shop, and is now headquartered in Austin, Texas. In 2004 COBB introduced the Accessport, a handheld ECU tuning device that flashes COBB’s off-the-shelf maps or a custom tune and doubles as a real-time gauge and datalogger. The range has since grown from Subaru to Ford, Volkswagen, Audi, Porsche, Nissan, Honda, Mazda, Mitsubishi and Toyota platforms, with intakes, intercoolers, exhausts and flex fuel kits engineered alongside the tuning, and many COBB parts carry California Air Resources Board Executive Order numbers for use in all 50 states.

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.
