Stainless Works 18-21 Grand Cherokee Catted Midpipe - JEEP62CAT

The Stainless Works 18–21 Grand Cherokee Catted Midpipe (Part # JEEP62CAT) is a purpose-built, high-flow mid-pipe upgrade designed specifically for the 2018–2021 Jeep Grand Cherokee platform. Engineered and manufactured in the USA by one of the most respected names in performance exhaust — Stainless Works — this catted midpipe replaces the restrictive factory mid-section and incorporates high-flow catalytic converters, giving you a meaningful upgrade in exhaust flow without going full off-road straight-pipe. If you're chasing more audible performance character from your Grand Cherokee while retaining catalytic converter coverage, this is the bolt-on mid-pipe solution built for your application.

Key Features & Benefits

• Made in the USA: Stainless Works fabricates their exhaust products domestically, a hallmark of the brand's reputation for build quality and consistent fitment across their entire lineup of performance exhaust and headers.
• High-Flow Catalytic Converters (Catted Design): Unlike a straight-pipe or resonator-delete option, this catted midpipe includes high-flow cats — a meaningful advantage for enthusiasts who want improved exhaust flow and enhanced exhaust note while maintaining catalytic converter coverage on the vehicle.
• 304 Stainless Steel Construction: Stainless Works builds their Jeep performance exhaust products from 304 stainless steel, a material choice that delivers long-term resistance to heat, corrosion, and the elements that a daily-driven SUV encounters over its lifetime.
• Direct-Fit Mid-Pipe Replacement: This unit is engineered specifically for the 2018–2021 Grand Cherokee application, meaning it's designed to bolt into the factory exhaust mounting locations without the need for custom fabrication or modification.
• Exhaust Flow Improvement: By replacing the factory restrictive mid-section with a higher-flowing catted design, this midpipe helps remove a common exhaust bottleneck, supporting better scavenging and exhaust gas evacuation from the engine.
• Pairs with Additional Stainless Works Components: As part of Stainless Works' broader Jeep Grand Cherokee exhaust ecosystem — which includes catback systems and headers — this midpipe can be used as a standalone upgrade or as part of a more comprehensive exhaust build.

Frequently Asked Questions

Q: Is this midpipe legal for street use in California?
A: No. The Stainless Works JEEP62CAT catted midpipe is not CARB (California Air Resources Board) legal and is explicitly not for sale in California. It is also subject to a California Proposition 65 warning. Outside of California, always check your local and state emissions laws before installing any aftermarket exhaust component on a street-driven vehicle.

Q: Does this come with everything needed for installation, or do I need additional hardware?
A: Our product data lists this as a midpipe kit. However, specific hardware inclusions (gaskets, clamps, hangers) are not detailed in the available product documentation. We recommend contacting our team at 813-535-5801 prior to installation to confirm what supporting hardware — if any — you may need for your specific build.

Q: Does this midpipe fit the Dodge Durango SRT or is it only for the Jeep Grand Cherokee Trackhawk?
A: Cross-referenced listings indicate the JEEP62CAT has been associated with both the Jeep Grand Cherokee Trackhawk 6.2L and the Dodge Durango SRT 6.4L platforms. Because fitment can vary by exact configuration, we strongly encourage you to contact our fitment team before purchasing for a Durango SRT application to confirm compatibility.

A: Stainless Works offers a range of Jeep Grand Cherokee exhaust components including catback systems, and their product lines are generally designed to be complementary.
