I've seen several people mention they've gutted their cats and used anti-foulers on the rear O2 sensors. How did you guys go about gutting the cats? I don't have access to a welder and the pipe bends kind of limit my nice 2ft flathead.

 

I would just take it an exaust shop and get them to remove them commpletly.

 

Doubt you'll find an exhaust shop to do that....

 

Up here they will

 

Exaust shops around here will

 

Same here ill post pics lol

 

They won't around here. Emissions are Federal law so gutting a converter would be breaking the law and businesses don't like fines for stuff like that. My driver side converter is rattling and the truck is running a bit rough and I don't feel like payin hundreds of dollars to replace em.

 

I've found you just have to talk them into it, tell them you will pay cash only without any receipts or anything proving they did it.

 

yea just tell them to cut behind them and take something and break up the inside and start the truck and blow it out the re weld the pipes back and beware they do charge MORE to cut out the cats i payed $120 the fist time then $180 to weld my muffler and Y-pipe i bought on

 

Just buy a new set of aftermarket High-Flow cats. They're way cheaper and are still legal.
