Hey guys i have cat failure on my left side. Does anyone know of a aftermarket cat for our cars or have a stock one. Also if so what company do you recommend.

and yes im out of the 80k warranty

thanks in advance

 

I went with OEM... the biggest concern for me is what caused the blockage? A failed coil?

 

Magnaflow Performance Polished High-Flow Catalytic Converters - JEGS

Magnaflow is kind of the standard. Anything "better" is going to be niche and significantly more money.

 

replaced all the coil already , now just a failing cat

i was even considering running straight pipe, have you ever heard of anyone doing that not sure how well the temp would be reglsted with the 02 before and after the existing cat , do you have a model number for which magnaflow cat ? thanks for the help

 

The 02 sensor after the Cat would be eliminated or a dummy plug put in to keep the CEL light off. You WILL smell gas if you remove the Cats... I did this in my last car which was far more sports car oriented than the GT/luxury Jag.

I don't have a model number... but high flow cats will make a bigger difference to performance than an exhaust since they will by far free up more airflow. In the car industry it's taboo; and even illegal in some states, to modify working cats.

 

Also, may want to check the bearing on your catalytic converter and muffler... just sayin'.

 

Thread update: gutting the cats this weekend and waiting on a new 02 sensor for before the cat . I'll post results .. Also to add I already have aftermarket mufflers and deleted the stock

 

Was it a muffler bearing?
