My ex-girl friend purchased an exhaust system for my 2002 Toyota Celica (not knowing what she was buying of course lol) the system did not come with the mid pipe that connects to the headers so you cant even tell that that I have an exhaust system on my car. If I remove the Catalytic Converter on the car will it make it sound nice? Im looking for a good street/tuner sound. Or what should I do? Should I just buy a whole new exhaust system?
as long as you don't have to pass emissions inspections I would eliminate the cats. That gives you a louder sound and also improves exhaust flow resulting in more power. You will need to have your O2 sensors turned off and without the O2 sensors you may need to have the car tuned for the performance you are trying to get. I would go ahead and install all the the upgrades you are wanting to do then get it tuned after that though. just so you don't have to keep throwing away money every time you make big change to the car.
Should not be a problem, maybe you nailed a pothole real good. Kinda hard to bend an axle in that car.
It doesnt do jack on HP if you remove the cat or make it any louder there is reasons why its there, also dont put a fart cannon on the exsuast. Go on youtube and type it 02 celica and just about all of them have em. Get a real toyota or pro toyota system with the proper headers, also invest in a GOOD turbo charger it is worth the cash if your gonna improve parts. Just dont R.I.C.E it or its just gonna be a loud cookie cutter 4 banger.
if you remove the catalytic converter from your car, you will need to replace it with a straight pipe. if you do this correctly, with a pipe that fits exactly, it will change the sound to a more deep throaty tone. however, you say that she purchased an exhaust system. does this mean catback exhaust, or a full headerback exhaust? if it is the full exhaust, from the engine all the way to the muffler then deleting the cat will change the sound dramatically, giving you that tuner sound. if not, it will sound more of what people call a rice sound. [meaning it will be loud and not good] i would suggest getting headers, deleting the catalytic and replacing with a straight pipe, and using an aftermarket muffler. [i use a flowtech raptor, which sounds very nice] without knowing what kind of exhaust system it is difficult to answer this question. deleting the cat will only sound good if you make other modifications as well.
Wouldn't hurt axles but there are other possible complications
