So I have some extractors for my 87' hilux (4y engine) that I am yet to put on, now I have just been to the wreckers (oxley) and was told there'd be a complete exhaust system available for my car. When I had a look around all I could find was a 2wd lux with a 2y engine; however, it looks to me like it could fit ? anyone know or think why it might not fit? would the pipe be the same diameter?
as a side question when installing my extractors what happens to the stuff sitting above my exhaust manifold ? looks like its connected in some way.
(I can add pictures if needed)
p.s. wreckers are so helpful
