Ok, so exactly how many cats do our cars have? If the XLR8 jpipe deletes one. And you guys are talking about deleting 2 more... How is this not throwing CELs.. Or what exactly are you "hollowing out" and where the hell is it located

Ack is hollowing out the two primary cats that are attached to each head on the engine. I think XLR8's J-pipe deletes the 3rd cat which is not monitored, so it will not trigger a Cel. As far as the two primary cats, a defouler is used to avoid a Cel. The primary cats are on the front and rear of the engine, were the exhaust leaves the heads.

Just curious if anyone ever did it on the car, maybe a few quick wacks, start the car to blow some material out, rinse and repeat until it's done.

Agreed. I can't imagine paying for someone to guy my cats. A hammer and prybar/long screwdiver is all you need. I almost did it myself but I don't feel like buying another set when emissions time comes around in 2 years. You're going to pay a lot more than the cost of precat deletes if you have to buy another pair of converters.

Thinking about trying to find some used cats at my local auto salvage and banging them out. These cats look like a pain to remove also. How long to remove for someone who has done it before. Also how much do the dufoulers run roughly? Trying to weigh my options on going this route or just getting pcd
