Will GS300 headers bolt up the sc300? And I did search but didnt find much. and would it a be an equivalent (as in exhaust flow) to the single exhaust or is one better than the other?

please, can anyone answer this?

Headers should mount up (2jz & 2jz). I don't think that VVTi has a different bolt pattern. Exhaust for a GS will not fit on an SC unless you mod it. The chassis dimensions are different for the two vehicles

Thank you for the responce! I know they have the same engine but didnt know if they did have different bolt patterns just because its two seperate headers vs. one. And I only want the headers, ill get full custom exhaust from the headers back. should I be able to get headers from any of the 1st and 2nd gen gs'?

If you take off the SC exhaust manifold, it's 2 pieces too

That should work, both have 2JZ. 1st gen is the exact same motor, 2nd gen has VVT-i which should still work.

It will fit the motor, but is there enough clearance in the SC?

Clearance is my biggest worry. I would do single exit because its much easier but I thought true duals would be more unique and still have the same effect without the extra butthole.I think both headers would fit but just the piping may be a bit of a headache. And thats interesting, I thought the flange would be just a one-piece deal.
