Description

QuickSilver Sport Exhaust for Land Rover Defender OCTA 110 P635

Few vehicles announce themselves quite like the Land Rover Defender OCTA 110 P635, and QuickSilver’s sport exhaust makes certain yours is heard exactly as it should be. Hand-built in England since 1979 from aerospace-grade T304 stainless steel, every system carries the coachbuilt expertise that has made QuickSilver an original-equipment partner to marques including Aston Martin. Its Sound Architect valve control places two distinct characters at your fingertips: a refined, unobtrusive calm for the long journey, and a full-blooded performance note the instant the mood takes you. It is precisely the sort of considered, quietly exclusive upgrade a vehicle of this stature deserves.

Design and Performance

Loud or Quiet – our system uses our revolutionary Sound Architect Module, which is controlled by our new standalone key fob. With the valves shut the QuickSilver system provides a civilised note which is unobtrusive and perfect for long journeys and early starts. Press the ‘Sport’ button to switch to valves open and the monstrous side comes alive with volume and pitch increased to deliver that V8 sound that enriches the experience. Furthermore, in OCTA driving mode, all the pops, crackles and bangs are present on the up-change & overrun, a nice touch. The QuickSilver system is truly plug & play, it requires no intrusion into the vehicle’s OE systems and is completely reversible (on resale?). Sound Architect® Remote Valve Control by QuickSilver The new QS Sound Architect® remote valve control system gives you full command of the sound. Our push-button fob can be mounted within the vehicle or used outside the vehicle if desired. Our Sound Architect system hands control of the valves back to the driver for the ultimate experience. When you select ‘Open’ they’ll stay open and when you select ‘Closed’ they’ll stay closed – this choice will be remembered even after the vehicle’s been turned off and on. The electronic module included only requires a 12v feed, usually a cigarette-lighter socket. Its binary functionality offers two distinct sounds to suit your environment. Our default ‘Sport’ mode offers the full experience with a deeper robust note and utilises the optimum flow of the exiting exhaust gases. With our ‘Refined’ mode, our exhaust harnesses the tone, offering a more civilised note when, and if it’s required. Even better is that like our exhausts, this is a simple install. Just feed the valve cables through the spare wheel well to the rear section, plug the power cable into the 12v in the boot, and you’re away! This style of valve control’s been requested a lot in the past, and we’re excited to finally offer this – the perfect sound is now just a button press away.

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.
