Why is it that the stock exhaust manifold looks just like a 4-2-1 header.
I have not seen this before on any other car. The tubes run just like an aftermarket header and to me the tubes look bigger. The only difference I see is that on the stock manifold all the tubes are connected on the sides to each other, whereas in the aftermarket header , the tubes do not touch till they connect to make 2 pipes. It looks pretty sporty.

the difference is in the diameter, specifically as it curves down. the headers are larger. but i agree, if there was a stock exhaust manifold that looked like someone actually thought about performance rather than looks or cost, its the SR20.
