Product Details

The MagnaFlow 51204 OEM Grade Universal Catalytic Converter is engineered to deliver reliable emissions control while meeting or exceeding Federal EPA standards for OBDII vehicles. This versatile universal-fit converter provides a cost-effective replacement solution for a wide range of applications.

Key Features:

  • 2-inch inlet and 2-inch outlet diameter for optimal exhaust flow
  • Round clamshell body design: 9 inches long x 4.25 inches wide x 4.375 inches high
  • Overall length of 13 inches including inlet/outlet pipes
  • Heavy-duty stainless steel construction for maximum corrosion resistance and durability
  • Ceramic substrate with expertly formulated catalyst blend for efficient emissions control
  • Continuous seam-welded clamshell design ensures superior thermal insulation
  • Integrated heat shield for added structural stability and heat protection
  • Built to OEM Grade standards matching original equipment performance and quality

Installation Notes:

  • Universal design allows precise placement and orientation for custom exhaust systems
  • Weld-on installation required (cutting and welding necessary for proper fitment)
  • Gaskets and hardware not included
  • Professional installation recommended

Emissions Compliance:

  • Federal EPA compliant for OBDII vehicles with Federal or California emission systems
  • Not CARB certified - not legal for sale or use in California, Colorado, or New York
  • Designed to help prevent check engine light illumination due to emissions faults

MagnaFlow catalytic converters feature precision-engineered construction with ribbed body design to minimize expansion and distortion at high temperatures, monolithic honeycomb catalyst for maximum flow and surface area, and lap-joint neck connections that don't extend into the converter body. This ensures unimpeded exhaust flow and long-lasting performance.

Great prices. Fast shipping. Huge inventory.

Great product. Fast shipping. Great and easy to use website! The air filter I purchased <br>From them cost $20 less than it was priced for at other competitors! I am very happy with the price.

great chair for pool table area or any man cave

I needed two fairly expensive parts for a project. Naturally, I shopped everywhere before deciding on where to purchase them. Autoplicity had the best price on the carburetor. I continued shopping around for the alternator, and ended up right back at the Autoplicity website, because they beat everyone else on that price also! And I don't mean by a few dollars! HUGE savings! Thanks Autoplicity! In the words of Arnold, "I'll be back!"

This was my first purchase on Autoplicity, it has been great will definitely put it in my favorites.

Quick and easy!

Super easy + best price on the web. Very pleased am I.

Fast shipping and saved $60 on a $399 item. However you have to verify your part #'s with the vendor. The part discription on autoplicity sometimes is not what you get. I ordered an item that said it was an O2 plug and bung but when it showed up it was just the bung plug sold separate and customer service basically said it was my bad for not checking for a more accurate discription on the Allstar web site.

ordered a K&N air filter, pretty simple. good price, timely shipping.

In a rush to get my car up and running, Autoplicity had the best price on the items I needed, and in stock as well as shipped quickly. Just what I was looking for, thanks!
