would my exaust sound really loud if i had all stock exhaust but no cat? keep in mind it had a really cheap ebay exhaust and headers before i dont care if it has a little sound but just dont want it to be so loud i cant talk to someone in my car

 

I have an srs exhaust and it's pretty quite but you can.. I have seen a car with a gutted cat and it had a metal zing to it.. The cat isn't a flow killer on exhaust systems it the muffler and small size pipe

 

why are you removing the cat?

 

in you remove or punch out the cat it wont be to loud as lond as you dont run a n1 style muffler

 

Because Ricer

 

This. Also, yes, it will make your car louder and buzzier. The cat operates as a secondary resonator, as well as an exhaust air purifier.

 

im not removing the cant im just converting the exhaust back to stock for now and dont have a converter but i do plan on putting on in later on

 

the cat*

 

well i plan on getting a cat or just a nice hefty resonator which do you guys reccomend? and if you know of a decent weld on cat res to fit ?

 

Get the cat bud, if you can't find an OEM one, go with Magnaflow they're not bad.

 

I figured the cat just for the simple fact that they are supposed to be there lol

 

and it is a felony to mess with it. not that any cop would ever check and know what ticket to give you but it is.

any universal one will work. just get the same pipe size bring it to an exhaust shop and tell em to weld it up. oem ones are like 800. universals are 100ish. just a heads up on that plan.

 

hello sir? Ah yes my good man id like to buy a $800 dollar catalytic converter please. Are you sure we have these universal ones that do the exact same thing for 100 dollars. oh quite sure my man i just happen to think the sheen on the 800 dollar one screems better worth. well if your sure(slips him the 100 dollar catalytic converter). oh my this is beautiful much better than that cheap piece thank you sir~! lmao i had too lol

 

hey is it possible at all to use a converter that doesnt have the o2 sensor hole in the middle of the pipe ? cause i have a new one of those

 

To a degree, you can run that but you will get a CEL from the lack of O2 sensor being there (if you're ODB2), you (if comfortable with it) can drill a hole in the cat, weld on a nut and in essence create your own O2 bung.
I've heard of people doing it, never done it myself, so take it with a grain of salt.

 

I think it would be nastier sounding... just the main 2.25 inch pipe tip on my muffler .. the main end small pipe comming off back of muffler came off and my car is loud when shifting through 1,2nd gear... it doesnt sound good... when I get a good paycheck Ive got my eyes on a whole new exhaust starting at headers back

 

Steer clear of ebay is my only warning, it may be cheap, but it will fall apart...

 

ok well i installed the exhaust and its great and not loud at all BUT my d4 is blinking happened after i got almost home my 02 sensor is in a bad spot i think would it do that if it burned out?

 

well good sir. its the name youre paying for. and anything OEM is expensive.

i've had my universal vibrant for 3 years and it works just as well. so yes it will. i've also tracked this car and i beat on it often.
maybe you should try a little research so you don't have to ask stupid questions like this to begin with. you know youtube(or maybe you don't since you made this) youtube.com try it. its got videos of crappy no cat exhaust abundant.

it will set a MIL light. idk how you have an o2 in a bad spot.
what year is this car even? since you decided we don't need to know this.
if its obd1 it'll mess up your fuel ratio.
if its obd2 it depends on which one it is. pre cat fuel ratio again. post cat who cares since its just for the cat.
and finally SEARCH. use google. this is an easy question.

 

Sorry you had to waist your time writing so much but Ronht has already answered all of my questions and the thread was only if it would be very loud I looked for hours on YouTube and only manage to fine one vid of stock catless exhaust and it was way louder than mine and it only temp I think I mentioned that in a above comment I plan to get a converter soon as I get the cash since the exhaust hasn't been the only thing I'm working on
