Since my race is this weekend, Im very tempted on removing the catalytic converter and leave the piping open at point before the cat. The reason being is the from the cat to the end Im being robbed ALOT of horsepower from the S/C. What risks are involved in doing this beside the check engine light coming on? Is it reconnectable? Can I use the same sensors once I reconnect the cat? Am I damaging the engine? Please help!!
P.s. the upside is that the Solara will ROAR!!!!!

maybe you can get a video or sound clip or something? there is sure to be a guy or two there with digital camcorders. see if they cant send a video clip or something.

You can either have a shop put in a test pipe for racing, which is a different insert w\ no cat, or you can gut the cat yourself which is free.. I just gutted mine

What do you mean by gutting the cat? What is it and how do you do it? Does it give you power?

Gutting the cat is basically taking a screw driver to the cat and breaking it apart into pieces.. it basically makes the cat an open tube.. its basically straight piping the car.. there is no real restriction there... have to be careful though when you do it because the Dust causes cancer.. wear a mask or something

You should look into a JPP y-pipe, if you haven't got one already. The stock y-pipe is super restictive.

how much is the jpp y pipe? Can you feel the difference? Is it worth it?

It's the most restrictive part of the exhaust system. . . yes you will feel something but nothing dramatic unless your blown
. . . but yeah JPP doesn't sell just the y-pipe anymore

so what then about removing the piping from the cat to the end? Any suggestions? How many sensors are there? I understand there are about 2 or 3 there. Please help, the races are tomorrow and I wanna kick some a$$ and get another trophy for the Solara!!!

Go to a shop and get a custom y-pipe made that deletes a CAT. . . easy as that
