question about headers

I just recently purchased the obx headers on ebay, few questions i currently have an efi live tune by slohawk performance and corsa xtremes, now if i install these headers will i need another tune asap or will the car be driveable and not worry about a tune until my intake, ported tb, and intake manifold come in? also i read about o2 extensions what size do i need to make these catless long tubes work i have a 2005 ls2 m6.

thanks

your tune will be ok. but if your running catless then it will trigger your SEL light and set codes. it will run ok and be safe with no tune. but you wanna tune it asap.

You'll need some extensions for the front, and bungs for the back holes since you aren't running cats. 24" is what you need I believe.
