I get a horrible rattle from my driver side cat, so i figure i may as well just gut them and take care of the problem. i have my rear 02s turned off already in my tune..

whats the best way to go about gutting the cats? is it worth the work?

 

depends on where you live...if you can get away without having them on there just throw on a set of longtubes and ory and call it done. if you dont wanna add headers right now and still need to at least pass a visual inspection just cut them off, beat all the **** out of them then weld a piece of straight pipe down the middle of them and weld them back onto the truck, problem solved

 

thats what i was figuring..we dont have any type of inspections or emmissions around here..i plan on getting some longtubes and ORY this summer, but i was just lookin for something for the time being..prolly more work then its worth since im eventually getting headers..

 

just put up with it till you get the longtubes and ory, unless you can get a good deal on getting them gutted at a muffler shop.

 

You positive it's not the O2s rattling? I know mine rattle like a BITCH.

 

Yea the 02s will rattle too... But I would just wait till you get l/ts

 

could be...i plan on replacing the 02s here once i get some cash...they are the only thing that is original in the motor/trans setup, so i may as well change them see if it helps my mpg..**** around town im getting >10..i am on it a little harder with the converter, but still..sucks

 

id say just wait...welding a couple pieces of straight pipe in there is more work than you would think. scrape up the cash and get a set of headers and a y-pipe and call it done!

 

Hell all I did was cut the end of each cat off, took an iron bar and broke the honeycomb up, fired up the truck and blew it all out then welded it back up, only took about an hour.

 

only problem with doing that is the risk of getting any of that crap stuck in your exhaust pipe or muffler. i know a few people have blown out their cats and had the honeycomb get stuck in their x-pipes or mufflers...then youd be in for even more work and possibly new mufflers
