Catalytic Converter Reviews - 2003 Lexus GS300

The CAT works well, and for the price is difficult to beat.

However, the install was not a direct swap as the manifold flange that bolts to the head was too tight of a fit but was easily modified to work. Additionally, the bracket that comes off of the bottom of the transmission has to be cut or drilled out to make it work like it did with the OEM CATS.

And as far as aftermarket low cost CATs go, this was one of the better ones.
