Ok so i have a 96 Ws6 with stock cats that are fried i wanted to do the carsound high flow but what cats do i need (Part#) and what type of Y pipe do i need to get can those mount into the stock one? please gimme all the advice you can

 

anyone?

 

come one anyone ive tried doing a search but it seems that everyone that changed the cats or Y had headers of some sort i have stock manifolds and just want to change the fried cats out with highflow cats...but i think than i would have to change the y pipe aswelll.....if anyone has a link or any advice i will take it...im tryin to finish up this winter project

 

I am in a similar situation, i wanted to do headers but i need to keep the cats because of emisions. I was either going to get the headers WITH the mac cats in the exactly the same location or just try and find cats from summit that would be a similar size. They have tons of cats to choose from if you go to there website and do some research on the dimensions of the drivers side cat i am sure you could find a high flow one on summit. The passenger side cat should be an easy match up IMO.
