I have a 93 rx-7, and am trying to remove the pipe from the cat. I see a wire is connected to something, and am not sure what to connect it to when i remove the pipe. I don't plan on driving the vehicle for long without the exhaust.



The nuts were on so tight (and they were different sizes ) and i was unable to remove them with my socket wrench. Are these nuts reversable or non-removable? Ahhhh......

They are just stuck. You need to spray them with something to free them up. The wire you are probably looking at is a ground wire. Just find a place to ground it to. Why are you driving without your exh.? I wouldn't boost without the exh. You may spike real high and hurt your motor.

uhh ohhh!!! that focker is gonna be loud.....

Thanks, and yes it should be loud. I probably couldnt keep it that way for long.



I just spent 8g's on a rebuild, and am afraid to of peaking, as any unnecessary detonation is not what Im looking for. Perhaps I should instead cut the muffler off at the back........

Y would you run it with no exhaust in the first place? As for the two different size nuts I think that's normal. At least it was the same on my car. As far as being tuff to remove I just got a really big breaker bar. OR you can use a jack at the end of the breaker bar to push up on it with a **** load of force. Be ready to break some sockets though. :smirk:

Well for an update: I couldnt undo those bolts, so i took my electric saw and chopped off the muffler, so now the exhaust is near the middle of the car.



Strangely, its not a whole lot louder, but it feels like its pulls harder, my wheels were even spinning in 3 gear.

it may have been less troublesome if you drove to a local shop and had them use air to remove the catback within minutes....

the cost would have been a lot less in comparison ...

meineke loosened some rusted studs in my old integra years back for 10 bucks...

Yea unless you gotta torch your better off taking it to your nieghborhood muffler shop.
