Universal Catalytic Converter, 2.5" Inlet/Outlet Catalytic Converter Universal High Flow Front Cat Convertor Direct-Fit with O2 Port & Heat Shield

I purchased this converter for a 2005 Hummer H2. It is well made, a little heavier than others I have purchased, and it fits perfectly.

Lo recomiendo

Perfect fit for my Ram with dual 2.5" exhaust. Includes the threaded bung for mounting your down pipe sensor and threads matched. Metal took welds nicely and didn’t burn. Took a little more effort finding the correct mounting angle but overall worth the money saved compared to the exact replacement that was several times this price. Requires a moderate amount of experience to go this route but can save you a lot of money. No sensor lights or leaks, so I’d have to say I recommend this product, it’s exactly as advertised.

Most modern cars have a catalytic convertor. It sits between the engine and the muffler, and is intended to reduce exhaust emissions. Unfortunately, the honeycomb design can occasionally become clogged, which can make your car feel sluggish on acceleration. When that happens, you have to replace the cat. I measured the diameter of the exhaust pipe entering my old catalytic convertor and ordered this one. It was a perfect fit. I took it to my local welding shop and was lucky enough to find one that could weld it in place the same day. While I did have to buy a new O2 sensor (recommended by the shop) it was much less expensive than paying over a thousand dollars for the same thing from my local car parts store.

I’m on a mission to get my small block powered G body street legal, and a pair of these is a key step! Where I live they not only test tailpipe emissions, they also slide a mirror under the car to visually verify that there are cats in place. These are 2.5” diameter with a monolith core for good flow, so hopefully I won’t be giving up too much power. Appears to be quality construction, so should last for years.

Just install this catalytic converter on my Chevy today because mine had a little hole in it it was a little loud. It welded on with no issues and I am glad

Fits good no issues. It either needs to be welded or mounted using pipe clamps, but still recommend spot welding at a bare minimum
