Federal / EPA Direct-Fit Catalytic Converter

Catco 9100 is a direct-fit catalytic converter built for specific Jeep Wrangler applications. It uses a ceramic substrate and stainless steel body construction, with OE-dimension manufacturing for consistent fitment and exhaust alignment.

Key Features

  • Federal / EPA direct-fit design for straightforward exhaust replacement.
  • Ceramic substrate for efficient catalyst loading.
  • Stainless steel body for corrosion resistance in exhaust service.
  • 2-bolt loose flange inlet with spherical flare for the listed applications.
  • 2.25-inch OD pipe outlet and two O2 sensor ports.
  • Built to exact OE dimensions for proper fitment.

Detailed Description

Catco 9100 is engineered as a replacement catalytic converter for Jeep Wrangler models with the listed front-pipe configurations. The unit combines ARISTO substrate chemistry with advanced manufacturing methods to support efficient converter loading while maintaining OE-style dimensions. For buyers searching for a Jeep Wrangler catalytic converter or a direct-fit exhaust replacement, this part number 9100 provides a fit-focused solution for the specified 1997-2000 applications.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

  • Failed catalytic converter efficiency codes.
  • Restricted exhaust flow from a worn converter.
  • Exhaust leaks at the converter connection points.
  • Emissions test failures related to converter performance.
  • Fitment issues caused by a damaged or incorrect replacement unit.

Installation Notes and Tips

Fits 1997-1999 Jeep Wrangler, N/A. Fits 2000 Jeep Wrangler, N/A. The 2000 application is listed for vehicles built to 1/24/00 and requires the front pipe configuration noted in the fitment data. Verify emissions requirements before installation, since the listing includes federal and California emissions notes and state-use restrictions.

Quality Assurance

Catco uses automated workstations, spinner welding equipment, and high-speed production lines to build converters to exact OE dimensions. The 9100 is manufactured with a ceramic substrate and stainless steel body for consistent exhaust service.
