Tomorrow I'm going to get some custom exhaust pipe made for my celica. I was wondering how much louder it would be without cat. I am gonna have 2 1/4 in piping with no resonators and a muffler. Also, I heard that if you dont have a cat there will be a very noticable smell indicating you dont have one. Third, would it give me any hp gains since the midpipe would now be 2 1/4 Last, how easy would it be for a cop to tell that you dont have one. I live in alabama and we dont have to go through any emissions or vehicle inspections

that rotten egg smell is the cat smell.... the cat has a chemical (some kinda of yellow stuff) sulfur.... all new cats smell like that... thats what i read in some mechanic article...

not sure if thats correct....but it is the sulfur

Ya my mom just got a matrix and you get that smell sometimes, not very pleasant
