K, so my cat is going bad, and I've decided that I want to just replace it and the rest of the exhaust, but I've got a few questions.

What's the stock inlet/outlet size for the cat / exhaust piping? Also, would you guys recommend a Magnaflow High flow cat?

I'm thinking of getting a Magnaflow high flow cat and Flowmaster Super 44 muffler, just wanted to know what the rest of this forum thinks. Vehicle is a '96 Blazer LS 2 door, by the way.

 

read a past that i have in here talking abotu high flow cats. everyone ive talked to abotu it says dont do it.im getting a magnaflow cat back exhaust for $120. i personally dont like the saound of a flowmaster on a 6. but you can do what youd like. im also getting a set of edelbrock headders to go along with it and i cant decide if im gonna keep the cat or not. if i do it wont be a high flow cat.

 

i forgot to add the exhaust is 2 1/2". im not sure about the cat.
