What is the difference between the 91-99 headers and the 00 headers, and is anyone running the older headers on there 2k G? I tried to e-mail hotshot and a few other places but no one wants to write back and tell me why I should buy there product:rolleyes: you would think they would do a better job of trying to sell there stuff.

On the 2000+ cars you have an extra 02 sensor right before the Cat.

Thanks for the info, so could I just cut in the other O2 sensor and make it work for my 2k?

I got the HS header and installed it. The only thing is like you said, there is another O2 Censor located next to the Cat...
I pluged that cesor whole and removed the censor completely
Will this cause any problems??? Will my ECU and performance be effected??? I plan on extending the O2 wiring and return it to its proper place... if the censor is located in a different possition... will that effect it as weLL???
