Will the Dual-Tip Stainless Cat-Back Exhaust fit my Mazdaspeed3?

It fits the second-generation BL Mazdaspeed3 sold in the US from 2010 through 2013, plus the world-market Mazdaspeed Axela and Mazda3 MPS from 2010 through 2012. The first-generation 2007 to 2009 car is not on the confirmed list, so check the model year before ordering.

Does this exhaust need a tune?

No. COBB does not list tuning as a requirement for this cat-back, which bolts to the stock downpipe using the factory doughnut gasket. A tune matters once the exhaust is part of a wider upgrade such as an aftermarket downpipe, so match the Accessport map to every part on the car.

Can I run the COBB Dual-Tip Stainless Cat-Back Exhaust with an aftermarket downpipe?

Yes, if the downpipe is a direct factory replacement. COBB states that the Dual-Tip Stainless Cat-Back Exhaust works with the stock downpipe, the COBB downpipe and any direct replacement unit. A downpipe with a different outlet flange would need an adapter, and none is supplied.

COBB describes the note as a mellow rumble, with two chambered resonators taking the harsh edge off without restricting flow. The system was designed to meet the 95 decibel limit even as part of a full turbo-back exhaust, and COBB lists it within the SAE J1169 sound restrictions.

Is this exhaust emissions related?

No. COBB classifies this cat-back as a part that is not emissions related, so it can be used on emission-controlled vehicles. Everything it replaces sits behind the downpipe, and the factory emissions hardware ahead of it is left unchanged when the system is fitted.

What comes in the box?

The complete cat-back system from the downpipe joint to the two 4 inch tips, with the resonators already built in, plus all gaskets and hardware COBB specifies for the install. The joint at the downpipe reuses the factory doughnut gasket, so keep it in good condition when removing the stock system.

Description

COBB Tuning 3-Inch Dual-Tip Stainless Cat-Back Exhaust for BL Mazda Mazdaspeed3

COBB Tuning’s Dual-Tip Stainless Cat-Back Exhaust swaps everything behind the downpipe on the 2010-2013 Mazdaspeed3 for T304 stainless steel tubing that runs at 3 inches to a split, then exits through dual 2.5 inch pipes and a pair of 4 inch slash-cut tips. It suits the Gen2 owner who wants more breath and a fuller voice with a note that stays short of overbearing. Owners chasing outright volume should look elsewhere, as COBB built it to stay under 95 dB even within a full turbo-back system.

Design and Performance

COBB laid the piping out to use as few total bend degrees as possible, which cuts back pressure, and kept it inside the factory exhaust path so it tucks close to the undercarriage for ground clearance. A primary and a secondary chambered resonator quieten the harsh frequencies without adding restriction. The Dual-Tip Stainless Cat-Back Exhaust is T304 stainless in a satin finish, with COBB-built resonators and rolled double-wall tips.

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.
