    Flowmaster's Universal Catalytic Converters are designed to meet federal EPA emissions requirements on a wide variety of applications. These high quality catalytic converters are manufactured in the USA, and feature stainless steel outer shell construction for maximum durability. The internal substrate material and precious metal loading have been carefully engineered for maximum efficiency and to avoid MIL (Malfunction Indicator Lamp) code issues that are common with lower quality converters. Universal catalytic converters require welding and/or fabrication. Flowmaster 49-state converters are not legal for sale or use on vehicles licensed or operated in the state of California.

    Features:
  • Available for a wide variety of applications.
  • Meets all EPA 49-state requirements.
  • Excellent flow characteristics.
  • Engineered to keep the "MIL" light off.
  • Stainless steel construction.

    2600230 is rated 2.0 out of 5 by 1.
    Rated 2 out of 5 by from Not efficient, but looks good... My Suburban had been barely passing smog as the old Magnaflow cat got older. It finally failed smog and I then got this cat. It looked great and the guy that does my exhaust work was surprised Flowmaster makes catalytic converters. Did I pass smog? Barely! This was only a small improvement on hydrocarbons (HC). It went from failing at idle to barely passing at idle AND okay 2500 RPM to barely passing at 2500 (2 speed idle test, no load). My buddy that does my smog tests said that hopefully it simply hasn't broken in but I drove about 12 miles with it. 1 miles street traffic, 3 miles in heavy traffic at East Coast "high" speeds and 4 in good old SoCal stop and go freeway speeds and I parked. The next day just before smog it was 3 miles of true high speed down the highway (70+) and about 2 street. If that didn't break in the cat and get it hot, I don't know what will. So I'm giving one star because that's the minimum, half star because it looks good externally and has excellent welding and half star because at least I'm good for 2 more years. I have my doubts it will pass in two years but let's see what happens.
