My local shop wont cut my cats off my truck and replac it with pipe. The only reason is because of emisions. What should I do? I can get the pipe and run it myself, I have a welder and all the tools to do this project. If I cut the 2 rear cats, will I risk throwing a code?

 

If there are 02 sensors on the cats, Yes, you will throw a code.

 

the O2's are right before the cats

 

If you ever own the truck in an area where they do emissions inspections, you will have to replace them. happened to me years ago. Not cheap.

 

just had my inspection in September, so I am good for another year, I am planning on replacing the entire exhaust with headers, hi flow cats, x-pipe and mufflers, but for now I want to be loud and obnoxious LOL

 

It will be obnoxious. Police will have it out for you, trust me.

 

will the shop add a flanges so that they do not "remove" the cats, you can claim for "off road only" and bolt on a straight pipe when you are "off road"

 

Agreed. Just with true duals I've got cops eyeing me too often to be comfy. I live right down the street from a police station so I keep it under 2K until I hit the highway.

 

the frt o2's are before the first set of cats, the second set of o2's are after the 2nd cats and just report they are working properly

 

I had hooker headers with no cats, no muffler true duals. No nothing but pipe straight from the engine. Got about 5 pipe tickets, the cops were always on the lookout for me, even had one tell me they had a call out for a "loudass white z71 with a duckhead sticker on the back glass"

 

Nice... too bad it was a Chevy

 

the muffler guy in our town will do anything you want illegal, pay cash and no receipt. have a nice day

 

The main reason they won't cut ur cats off is because it isn't older than 10years. After 10 years I believe the vehicle can be modded like that. Its a law here in NYS that shops cannot touch emissions equipment until the vehicle has aged to past 10 years. So the one dude told me anyway.

 

Why do you think I turned it inot a POS.
