GXP Headers?

Does anyone know if the Kooks headers will fit the GXP? Seems like there shouldn't be any differences in fitment. Also, can I run the long tubes with catted x-pipe but retain my factory mufflers?

Thanks!

ARH and Kooks have both said they will fit. The LS3 external dimensions are the same as the L76 so the bolt on mods will work for both.

The only think I could see being a difference if if anything on the M6's get in the way.

aren't the manual boxes smaller than the autos?

If they are it's not by much. The T-56 (or what ever GM code they call it these days) is one big ass manual tranny but it strong as a horse so I'll take the trade off.

I agree the headers in theory should fit but I'd just want to double the check the hydraulic lines for the slave and the differences, if any, in the cross member.

It's called the TR6060.

I can confirm that Kooks Long-Tube Headers fit on an M6 GXP with absolutely no issues. They sound awesome, and I can't wait to see what difference they make at the track. I wish I had bought these sooner!
