What is the Valvetronic Designs Exhaust System for X290 AMG GT 63 made from?

The Exhaust System for X290 cars is built from ultra-light titanium, mandrel-bent and precision TIG welded at every joint. Titanium is lighter than the factory steel at equal strength and sheds heat faster. Valvetronic Designs backs the titanium tubes and welds with a lifetime limited warranty against defects in workmanship or material.

Does it fit the GT 63 S as well as the GT 63?

Yes. Valvetronic Designs lists this system for both the GT 63 and the GT 63 S on the X290 chassis, which share the same 4.0-liter twin-turbo V8 and the same rear packaging. One system covers both cars, so the choice at checkout is the configuration rather than the model.

Does it work with the factory valve control?

Yes. The electronic valves integrate with the exhaust control already fitted to the car, so the drive modes behave the way the owner expects and no separate aftermarket controller has to be mounted in the cabin.

Does it drone at a cruise?

No. Valvetronic tunes the system for a deep tone with the drone reduced on the closed setting, which is what makes a large catback livable on a long highway leg. Opening the valves is then a deliberate act rather than something engine load does on its own.

What is the difference between the two configurations?

The catback covers the rear of the system. Adding the Race Free Flow Front Pipes carries it further forward, which frees up flow and adds another step in volume and throttle response. Both share the same titanium construction and the same valve integration.

Description

Valvetronic Designs Valved Sport Exhaust System for X290 Mercedes-AMG GT 63 & GT 63 S

Valvetronic Designs’ Valved Sport Exhaust System for X290 Mercedes-AMG GT 63 and GT 63 S answers the one thing the four-door AMG never quite delivers: a voice equal to the way it moves. Valvetronic designs and builds every system in-house in Boyertown, Pennsylvania, and this one is formed from ultra-light titanium, mandrel-bent and precision TIG welded throughout. Electronic valves integrate with the factory exhaust control, so the 4.0-liter twin-turbo V8 holds its composure at a cruise and turns deep and openly aggressive the moment the driver asks.

Construction

Titanium is what separates the Exhaust System for X290 cars from a steel replacement. Valvetronic mandrel-bends the tubing so it holds full diameter through every bend rather than pinching at the corners, and TIG welds every joint by precision rather than by volume. The system comes in lighter than the factory steel it replaces and sheds heat faster, and Valvetronic Designs backs the titanium tubes and welds with a lifetime limited warranty against defects in workmanship or material.

Sound and Valve Control

The electronic valves integrate with the exhaust control already fitted to the car rather than a separate aftermarket module, so the drive modes behave exactly as they did. Closed, the tone is deep and composed, with the drone that spoils a large catback engineered out of it. Open, the 4.0-liter twin-turbo finds the hard-edged AMG voice the factory system keeps under wraps. The Race Free Flow Front Pipes configuration carries the system further forward for more volume again.

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.
