i've found these on ebay.com...

ebay clicky

they are listed for the is300, but im hoping they will fit the gs300.... can anyone confirm this?

also in the pictures it looks like it has 3 holes for the o2 sensors, so maybe they wont set off the cel light?

trying to remember from the top of my head, are there 2 pre-cats on the standard manifold?
on my previous car i removed the pre-cat leaving the main cat and it passed emissions fine.

has anyone got a manifold on their gs?

cheers

shake

i doubt it will fit the GS, easily, but i recon some minor reworking of the thing could make it fit to the remainder of the system

how would a na supra header fit?
i want more power!

again its a different car...it can be made to fit......as could the IS300 one
