As with any non origina equipment have to do little cutting and matching pipes and fair amount welding. I also added 3 sensors into exhaust then erased PO420 code and after 100 miles check engine light still off. It seems be doing its job.

Well made... fit perfect. Wish I had gotten better information on the o2 sensors. Some people say you can clean them, others say you can't. It would be a lot easier to replace them when you are changing out the Catalytic Converter. Especially the right front. The electrical connector is difficult to get to. [...]

CAT worked great on my 01 Blazer in CA.
CAT worked great on my 01 Blazer in CA.
Submitted 2013-12-24
By bigdeezs
From Los Angeles, CA
The stock catalytic converter was clogged on my 2001 Chevrolet Blazer I believe due to fouled spark plugs or just worn primary ignition components. After replacing the spark plugs, distributor cap and rotor as well as spark plug wires. The vehicle would not rev past 3000 RPM. I found the factory CAT was clogged so I ended up purchasing this CAT because it was the least expensive California legal CAT with CARB EO# for my vehicle. After cutting the stock cat out and welding this one in my blazer ran great. I never tried to get a California smog check though because the truck was stolen before I had a chance 🙁

This part is a full 4" shorter than the original. It did not come with clamps to install it on the tail pipe. I was not able to find the clamps on line. I'm going to have to return it and hope a correct replacement is available.
