Default Louder car

8m ago when i installed LG longtube headers with high flow cats and SLP LM exhaust my car was very loud. But for some reason it quieted down or i just got used to it. Even my dad says its not as loud as before.
Should i remove Cats? Will removing them make the car significantly louder or not? Also will it stink on fumes if there are no cats?

I went from stock, to catless headers and NPP and there is definitely quite a bit of smell. I always feel bad if I'm going through a drive through or something. It doesn't bother me, because I knew it was an inherit risk with going catless.. but there is definitely a smell. But I don't smell it with the windows up, only when it creeps in with the windows down.

As far as sound, my car is pretty loud... but I don't have anything to compare it to. Not sure how much of a difference the cats make.

Catless is a good bit louder and yes you will smell it at stoplights

I had the offroad for 4 years and that was exactly 4 years too long. The sound was off the chart but so was the odor!
