After a couple weeks of struggling with a heavily clogged cat, i ended up ordering what is supposed to be a direct fit replacement through ebay from "Autoparts Warehouse" It is not marketed as a high flow cat, however it is a 3 INCH cat with a step down pipe on it to bolt up to the stock B-pipe, so even though i dont think it is technically a high flow cat, it is larger and in theory, a higher flow rate. I will be taking comparison and install pics monday.

on a side note, if anyone wants to buy one, its cheaper on ebay, search the part #, i found it listed for a LeSabre and got it for 137 Shipped

I was told by Magnaflow that its patr number 94805. But i dont know if this is direct replacement with flange. I need to replace mine too, and need some help.

Please don't dig up old threads. Feel free to start a new thread with a link to this one.

Thanks!
