1994 Mustang removing catalytic converters!

I have a 94 mustang vert with true dual exhaust and summit racing mufflers. I want to remove my catalytic converters to make my car louder. In fact I want it to be as loud as possible. (and yes i know it will never sound like a v8 so please dont say that) The problem is i am still in school and my dad won't let me remove them because he says the car will run like crap because of the o2 censors in front and back of the cats.
Is this true?
If so how can I take my cats off without the engine running poorly.

I need a louder exhaust, my v6 gets no respect at school.
thanks

Your dad's right about it not running properly. It wouldn't be necessarily about the sensors but it would lose a lot of torque by taking the converter off, and with a V6 you don't have much to spare. At this point you're not making enough power to compensate for this loss and it won't run like you would think. Again, you won't gain power, you'll lose torque.

Ok, I see your point. Is there another way to make my exhaust a lot louder??? I'm open to all suggestions, just tell me what I need to do.

I wouldn't worry about making your car louder. When I was in high school, we made fun of the guy with the loud car that was slow. If I was in your situation I would focus my efforts on making the car perform better and ignore what others say about it. Good luck with your ride.

I live on the main st at college, the loud ass cars are the annoying ones that everyone hates, I dunno how they stand being in those cars. my old 94 had flowmasters and when i got my new mustang i decided then and there that I'll never do an exhaust set up again, just kills the ride to me lol.

Either way, you want you car loud, didn't ask our opinion, it's what you want. you'll lose back pressure by removing the cats, no go there. Other than that to make it loud?

Well in theory if you slap on a SC or Turbo you can open her up to compliment the added intake therefore allowing you to remove your cats and scream down any road you want

increasing power to the engine will allow you to upgrade your exhaust, so priorities, it's just not cheap.

You will be the laughing stock in the school parking lot when you're revving a 3.8 with removed cats.

You will sound worse than ricers with a 10" fart cannon.

If you want a good sounding loud, save up your money. Port swap, intake spacer, camshaft, etc.

Drill a couple holes in the muffler, you'll be as loud as you wanna be!

Woe to him who builds his palace by unrighteousness,his upper rooms by injustice,making his countrymen work for nothing...Does it make you a king to have more and more cedar?Did not your father have food and drink?He did what was right and just,so all went well with him. He defended the cause of the poor and needy,and so all went well...But your eyes and your heart are set only on dishonest gain,on shedding innocent blood and on oppression and extortion.

If you really wanted to remove your cats you could get a tuner that would turn off the o2 sensors. If you want to make your car louder the trick would be taking off the cats while still having enough back pressure which is pretty hard to do. I heard alot of good stuff about violator mufflers from pypes,if you look threw the posts there are some sound clips of mustangs with them.

Just turn up your music louder and you won't be able to hear the exhaust anyway. That's what I do......

You can drill holes in your muffler, but I don't suggest doing anything like that due to the chance of exhaust vapors getting into the cabin. I know that KS has also given the "thumbs down" on this before with another member.
