Will these boss headers from Kooks fit the gt without any mods? 60-42-CATH-302-BOSShttp://www.kookscustomheaders.com/lib/sarp.php?func=show&src=../photos/productphotos/Boss_H-pipe_w_Coyote_headers_copy.jpg Thanks for any answers.

I would say yes. I am also thinking about getting the side exhaust with my LT and o/r h pipe.

Yes, but you need to buy either boss OEM side pipes or the ones from kooks

Stainless works also makes one

So, full bolt on, NO TUNE required? What advantage is there with these headers versus the stock GT headers?

Probably not a lot like any other mod that's no tune required would be my guess...

These have catalytic so no tune is required. I life in florida so the more pollution out the back the better!

You still need a tune because the LT's will move your cats further down stream and its causes the o2 sensors to read incorrectly. It will still throw a cel code

That's what I thought, just wanted to make sure.

Thanks.

No worries, I was just making sure I was correct in my thoughts about headers. I like that set up and the side pipes, could be a nice mod on mine. Just not sure about the tune. I need to see what Ford says they can do with a tune.
