What are the SOUL Performance C8 ZR1 downpipes?

The SOUL Performance C8 ZR1 downpipes are competition downpipes built in-house for the Chevrolet Corvette ZR1 and ZR1X (2025-present). Featuring 3.5-inch diameter piping and 32.5 lb weight savings, they deliver dyno-tested gains of over 100 whp and 130 ft-lbs of torque with factory hardware on 93 octane fuel.

What power gains can I expect from the SOUL C8 ZR1 downpipes?

Independent dyno testing at Vollux Autowerks revealed max gains of over 100 whp and 130 ft-lbs of torque at 4,000 RPM with factory hardware and 93 octane fuel. A second test at KIES Motorsport with the full SOUL Competition Exhaust System, Soler Performance Throttle Bodies, and a JB4 piggyback device added over 110 whp and 163 ft-lbs of torque. Race fuel can support over 1,200 whp.

Which Corvette models do the SOUL C8 ZR1 downpipes fit?

The C8 ZR1 downpipes fit the Chevrolet Corvette ZR1 (2025-present, 5.5L V8 Twin-Turbo) and ZR1X (2025-present, 5.5L V8 Twin-Turbo Hybrid), as listed in the Applications section above.

Is an ECU tune required?

A tune is not required to fit the C8 ZR1 downpipes. Those running a tuning device should expect even greater gains from the increased efficiency and larger 3.5-inch piping.

Is professional installation recommended?

Yes. We recommend installing the Competition Downpipes through a qualified technician to ensure correct fitment and a proper seal.

Description

SOUL Performance Competition Downpipes for Chevrolet C8 ZR1 / ZR1X

The SOUL Performance C8 ZR1 downpipes are engineered for the Chevrolet Corvette ZR1 and ZR1X for those seeking to use their car in a competition setting. Bumping up to 3.5-inch diameter piping with a smooth transition down to 3 inches to mate with the factory rear exhaust section, they deliver maximum flow and a significant increase in performance. Weight savings of 32.5lbs further benefits overall vehicle handling. Each set is built in-house from mandrel-bent 0.065-inch T304L stainless steel with hand-applied heat shielding and water-jet-cut flanges to ISO 9001:2015 standards.

Dyno Proven Power

The greater flow from the SOUL C8 ZR1 downpipes results in better response under all conditions and a noticeably harder pull throughout the power curve. Independent dyno testing at Vollux Autowerks on the SOUL development car revealed max gains of over 100 whp and 130ft-lbs of torque at 4,000 RPM, and peak gains of roughly 55whp and 30ft-lbs of torque, with factory hardware and 93 octane fuel. A second round of testing at KIES Motorsport with the full SOUL 3.5-inch Competition Exhaust System showed further gains, and the addition of Soler Performance Throttle Bodies and a JB4 piggyback tuning device added over 110 whp and 163 ft-lbs of torque. With race fuel, power numbers over 1,200whp are within reach.

Hand-Crafted Construction

Each set is built from mandrel-bent 0.065-inch T304L stainless steel tubing. Back-purged TIG welding with ARCAL Prime argon gas ensures proper weld penetration for exceptional strength and longevity. Water-jet-cut flanges and brackets are manufactured to ISO 9001:2015 standards with tolerances of +/- 0.003 inches for extreme precision. Thick-gauge aluminum fixtures act as heat sinks during welding to prevent warpage, and hand-applied heat shielding prevents radiant heat from entering the engine bay.

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.
