I have been looking at cat replacements; was going to cut the old cat out and put in a new one, but there is a support rod right at the cat inlet and the piping curves very close to the cat inlet and outlet....making cutting it out rather difficult.

Soooooo.....next option is to get the Y pipe with both pre cat and cat that bolts in, but there are like 5 choices that RockAuto lists....just wondering if anyone has a recommendation for one.

Thanks.

 

I am guessing you are looking at universal replacements
I would go this route
More Information for WALKER 50542

 

Not sure why the Walker 50542 is a universal replacement?..seems like it only fits the 4dr Blazer.
Did notice that the picture does not show the support bracket that mine has....makes me wonder if that is something I will have to cut off and weld onto the new one whether I go with the Y pipe or just replace the cat itself.

 

not a universal ,that should be a direct fit replacement
