I have 2 codes, 1 and 43 (if i remmeber correctly) I hear 43 might be caused by the bad O2, can the bad O2 be caused by a clogged cat?
If i gut the cat and weld a pipe on the inside how much is tha gonna change the sound of my exaust?? I don’t have a resonator just and high flow muffler.
Quite a bit. I have a gutted cat with a stock exhaust. The exhaust is pretty quiet in the car, and not terribly loud outside of the car but it definitely has a lot more sound to it, If you have a high flow exhaust with less of a “noise dampener” it will be a good deal louder. I don’t understand what you mean by welding a pipe on the inside. All you need is two longer thin bolts, two washers and two nuts and you can replace just the bolts, no welding, I used those which i found just lyin around, and then some $2 exhaust system glue and there are no leaks.
You will notice some smell after you’ve gutted your cat, to do so though you’ll need a really big hammer, and a really big metal rod, cause it does not come out easy. Honda packed those things
