Need to get a new cat. The Magnaflow looks like the one to get but it's $380. On Rockauto you can get the Eastern or Walker for about 1/2 that but I don't want to get a cat that gives me problems with not lining up with the factory bolts. Anyway, any experience with either of these? FYI I'm replacing the cat connected to the upstream o2 sensor. Thanks for any help!

 

I have had no problems with the Walker Cats

I run them on both 3.4 Vehicles .

They are easy to find .

Then I run the complete Walker Exhaust System.

 

Okay thanks...maybe I'll give that one a try.

 

Used Walker mufflers years back but am using a magnaflow cat forward system currently for three years without issue on my T4R.

 

That's reassuring Thor. I was wondering how long those magnaflows can last. Just put a set on my Cali-specs runner. Of course longevity depends on how well the rest of the engine and sensors are maintained.
