MagnaFlow 91076 Standard Grade Universal Catalytic Converter 2.5in Oval Pre-OBD

Vehicle Fitment

• Universal fit - not vehicle-specific. Designed for pre-OBDII vehicles (manufactured before 1996) running 2.5 in. exhaust piping that require a Federal/EPA compliant catalytic converter replacement. Cutting and welding are required during installation. Verify your vehicle's emissions designation before purchase - this converter is intended for pre-1996 Federal/EPA registered vehicles only.

Fitment Notes

• Standard Grade - designed for pre-OBDII vehicles (pre-1996 model year); NOT suitable for 1996 and newer OBDII vehicles - use OEM Grade 51006 or 51206 for OBDII applications
• Universal design - cutting, welding, and tube-bending are required for installation; this converter does not bolt directly onto any factory exhaust system
• Inlet is angled - confirm routing geometry before purchasing; the angled inlet is a key dimensional difference from center/center universal converters
• Federal/EPA compliant - NOT legal for sale, installation, or use in California, Colorado, or New York
• No O2 sensor ports included - if your application requires an O2 sensor bung, it must be welded on separately
• No AIR tube adapter - not compatible with secondary air injection systems
• Gaskets, clamps, and hangers are NOT included
• Professional installation by a qualified exhaust shop is strongly recommended

Features

• Standard Grade Federal/EPA compliant design meets or exceeds EPA emissions requirements for pre-OBDII Federally registered vehicles (pre-1996 model year)
• Compact oval clamshell body (7.75 in. L) - the shortest overall length (11.5 in.) in MagnaFlow's universal oval 2.5-inch converter lineup, designed for tight-clearance pre-OBDII installations
• Angled inlet geometry designed to accommodate specific routing requirements common in pre-OBDII exhaust system configurations
• Clamshell body features a continuous seam weld for superior structural integrity and thermal insulation over traditional stamped body designs
• Ceramic honeycomb substrate delivers high conversion efficiency and strong thermal durability across a wide operating temperature range
• Ribbed body design minimizes heat-induced expansion and distortion while holding the ceramic catalyst in proper alignment
• Seam weld positioned close to the converter body - not at the edge - prevents accordion-style expansion that allows the substrate to shift
• Funneled inlet and outlet cones with a 1/2 in. lap joint keep the pipe neck from intruding into the converter body, preserving unrestricted exhaust flow
• Integrated stainless steel heat shield attached to the body provides thermal protection for surrounding components and adds structural stability
• High strength 16 gauge 409 stainless steel tubing provides exceptional corrosion resistance and maximum service life
• Expertly formulated catalyst blend maximizes emissions conversion efficiency to keep the check engine light off
• Made in the USA from MagnaFlow's Oceanside, California facility and backed by MagnaFlow's warranty

Product Description

The MagnaFlow 91076 is a Standard Grade Federal/EPA compliant universal catalytic converter engineered for pre-OBDII vehicles - those manufactured before the 1996 model year - running 2.5-inch exhaust piping. This is a critical application distinction: the 91076 is specifically designed and rated for pre-1996 Federal/EPA registered vehicles, and is not appropriate for 1996 and newer OBDII-equipped vehicles, which require an OEM Grade converter such as the MagnaFlow 51006 (oval) or 51206 (round). With a compact oval clamshell body measuring just 7.75 inches in length and 11.5 inches overall, the 91076 is one of the most space-efficient 2.5-inch universal converters in MagnaFlow's catalog, designed to fit older exhaust routing with limited underbody clearance.

A key distinguishing feature of the 91076 is its angled inlet geometry, which accommodates the specific pipe routing angles common in pre-OBDII vehicle exhaust systems. The clamshell body is continuously seam-welded close to the body for a strong, leak-resistant bond, and a ceramic honeycomb substrate provides the necessary conversion efficiency to reduce hydrocarbons, carbon monoxide, and nitrogen oxides. The ribbed oval body resists thermal distortion and keeps the catalyst in proper alignment throughout the converter's service life. A factory-attached stainless steel heat shield protects surrounding components from radiated heat.

Because this is a universal converter, professional installation requiring welding, cutting, and tube-bending is necessary. There are no O2 sensor ports; bungs must be welded on separately if required. Gaskets, clamps, and hangers are not included. This converter is not CARB certified and is not legal for use in California, Colorado, or New York. Made in the USA at MagnaFlow's Oceanside, California facility and backed by MagnaFlow's warranty for pre-OBDII Federal vehicles.
