Does the Boost Logic Valved Rear Section for R35 fit the factory exhaust?

No. The Valved Rear Section for R35 is designed only for the Boost Logic Magnum 4.5 inch titanium exhaust and replaces its muffler section. It does not include tips, so the tips already fitted to the Magnum system are reused. Owners of the Boost Logic 4 inch titanium exhaust have a separate valved section made for that system.

How much quieter is the valved section?

Boost Logic states that the valved system reduces sound levels by roughly 10 dB on average compared to the non-valved Magnum section. The difference is greatest while cruising below 7 psi, when the valves stay closed. Once boost rises the valves open and the sound returns to the aggressive character of the full race exhaust.

How are the valves opened?

The valves are boost activated. Boost Logic sets the system to keep a refined, subdued tone while cruising under 7 psi and to open the valves as the car comes onto boost above that point. That gives the car quieter manners around town without giving up flow at full throttle, according to Boost Logic.

Does the valved section cost power when the valves are closed?

Boost Logic says no. It designed the valved section to avoid unwanted back pressure or performance loss with the valves closed, and states that once open the system matches the flow and power potential of its full race exhaust. Boost Logic does not publish separate dyno figures for the valved section.

Are exhaust tips included?

No. This is the muffler section only, and Boost Logic requires reuse of the existing tips from your Magnum 4.5 inch exhaust. Check that the current tips are in good condition before installation, since they transfer across to the new valved section rather than being replaced as part of this purchase.

Description

Boost Logic Magnum 4.5-Inch Valved Rear Section for R35 Nissan GT-R

Boost Logic’s Valved Rear Section for R35 Nissan GT-R is a boost-activated valved muffler section made to fit only Boost Logic’s Magnum 4.5-inch titanium exhaust. Cruising under 7 psi it keeps a refined, subdued tone, and as boost rises the valves open for the full sound and flow of the race exhaust; Boost Logic puts the average reduction at roughly 10 dB compared to the non-valved Magnum. It is the right part for a Magnum owner who drives the car daily and wants it quieter off boost. It is the muffler section only and reuses the tips already on the car.

Design and Performance

Boost Logic designed the valves so that the closed position adds no unwanted back pressure or performance loss, and says the open position matches the flow and power potential of its full race exhaust. The result is a Magnum system that is easier to live with around town while keeping the flow of the non-valved version at full boost.

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.
