Does the Cat-Back Exhaust for MK7.5 Volkswagen GTI require a tune?

No. COBB sells this system as a direct factory replacement and states that no tuning is required, so a stock GTI or one already running an Accessport map can take it as is. A later downpipe upgrade is the stage that calls for a matching map.

Can I keep my stock downpipe?

Yes. An adapter is supplied that tapers the inlet down to meet the factory downpipe on the 2017 to 2021 GTI. Owners who have already fitted the COBB 3 inch downpipe can leave that adapter in the box and bolt the cat-back straight to it, keeping the full 3 inch diameter through the joint.

Which model years of the Golf GTI does it fit?

Confirmed applications list the 2018 to 2021 USDM Golf GTI in manual and DSG form, plus the 2017 world market Golf GTI in both transmissions. The earlier 2015 to 2017 USDM MK7 GTI uses a different COBB part, number 5V2100, and the Golf R is not listed for this system.

How does the Cat-Back Exhaust for MK7.5 sound on the road?

The Cat-Back Exhaust for MK7.5 makes engine resonance and turbocharger noise noticeably more present than the factory system. An 18 inch inline resonator sits ahead of a 12 inch COBB stamped muffler to keep the volume in check, a sensible balance for a GTI that still commutes daily.

Is this exhaust legal on an emissions controlled vehicle?

Yes. COBB states that this cat-back is not an emissions related part and can therefore be used on emission controlled vehicles. It replaces only the piping, resonator and muffler behind the catalytic converter, so the emissions hardware on the GTI stays in place and untouched during the install.

Description

COBB Tuning Cat-Back Exhaust for MK7.5 Volkswagen GTI

COBB Tuning’s Cat-Back Exhaust for MK7.5 Volkswagen GTI is built for the 2018 to 2021 USDM car, and the 2017 world market model, in 304 stainless steel, running a 3 inch section that divides into twin 2.5 inch pipes and ends in dual-walled 4 inch tips carrying the COBB logo. It is a sound and appearance upgrade first; COBB lists no tuning requirement, and drivers chasing real power should pair it with a downpipe and tune.

Sound and Construction

Volume is managed by two stages of silencing: an 18 inch inline resonator up front and a 12 inch COBB stamped muffler toward the rear, letting turbo and engine character through without making highway cruising a chore. The Cat-Back Exhaust for MK7.5 ships with an adapter for the factory downpipe, and the same system bolts directly to the COBB 3 inch downpipe once that adapter is removed, so it can stay on the car through later stages of a build.

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.
