Is the inner silencer included?

No. The inner silencer is a separate, optional purchase. The manufacturer specifies its FX-PRO inner silencer for this exhaust, which lowers the volume when fitted. Add it to your order now if the CR-Z is a daily driver or you expect noise limits at track days.

What does the R304 50RS Exhaust for ZF1 cars sound like?

The R304 50RS Exhaust for ZF1 cars has the smooth, high-pitched tone the manufacturer associates with stainless steel when the engine is revved out, becoming sharper on a circuit. On VTEC engines the switch to the high cam brings a crisp popping note. No decibel figures are published.

Why a 50mm main pipe?

The manufacturer chose a 50mm main pipe to emphasize the mid and upper rev range without sacrificing low-rpm response. It also says the added torque improves throttle response, so the exhaust suits a CR-Z that spends most of its time on the street as well as one that visits the circuit.

Which CR-Z models are confirmed?

The manufacturer confirms fitment on the ZF1 CR-Z with the 1.5L LEA hybrid engine, which covers 2010 to 2016 production in our application list. Fitment on the ZF2 has not been confirmed, so contact us before ordering if your car is a ZF2.

What materials are used?

The main pipe and silencer are SUS304 stainless steel, at 1.2mm and 1.0mm wall thickness respectively, joined with hand TIG welds. The tail is titanium with a cut-bend dolphin shape. The flanges are made as thin as possible to keep total weight down, though no weight figure is published.

Description

J’s Racing R304 50RS Exhaust for ZF1 Honda CR-Z

J’s Racing’s R304 50RS Exhaust for ZF1 CR-Z owners is the SUS Exhaust Plus 50RS, a semi-titanium design that pairs a SUS304 stainless main pipe and silencer with a titanium tail. It keeps J’s Racing’s full straight-through layout, every weld is TIG-welded by hand, and the cut-bend dolphin tail is the same style used on the FX-PRO full titanium line. A 50mm main pipe favors the mid and upper rev range without giving up low-end response, and ultra-thin flanges trim weight further. It suits the CR-Z owner who wants a crisp stainless note and less weight; buyers who want a quieter car should add the optional inner silencer.

Design and Performance

J’s Racing says the extra torque sharpens throttle response, so the car feels lively even around town. Revved out, the stainless body gives a smooth, high-pitched tone that turns sharper on a circuit, and VTEC engines produce a distinct crack as they switch to the high cam. Each exhaust is finished by hand by J’s Racing craftsmen.

About J’s Racing

J’s Racing was established in Osaka in 1989, as VTEC engines and lightweight Civics and Integras were changing what a Honda could do, and it has built parts for Hondas ever since. The company develops engine response, suspension, braking, cooling and aerodynamics together as one system, then proves the parts in time attack, gymkhana, endurance and circuit racing. Its Fit lapped Tsukuba Circuit in 1’00.459, and its naturally aspirated AP1 S2000, the Maou car, became the company’s reference build for the Honda roadster. Every J’s Racing part is designed and tested in Japan, and J’s Racing USA in Carson, California handles distribution in the United 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.
