CATALYTIC CONVERTER

Good job all around. Thanks!
Eastern Catalytic is my go to brand. Direct fit every time so far, gasket & clamps included. Just add bolts for flange connections. The inclusion of flange head bolts nuts would make these the perfect package. Bolt it on, run the scan and ck the data. Job done. Strongly recommend over OE & Walker for price. EC look up chart could use some work and an interchange from Walker and OE would be the cherry on top. Carparts.com is a great supplier.

This is the only aftermarket brand that will work on the Cadillac Deville. Others will still trigger a check engine light. It’s either this or a 1300 dollar OEM one. The Evan Fischer brand is a disaster. I had to return and get this. Stick with eastern catalytic.
