stock exhaust

[ah_alex_]

Just a quick question... anyone know the stock exhast size? Dont have enough money right now to go full exhaust so im wondering if i could go 2.25" piping from the stock manifold back for now and put headers on later. I have a exhaust leak somewhere near the cats but my manifold is still in good shape. Any help is greatly appreciated

Stock exhaust size is 1.75" internal diameter.

You could go 2.25" from header back, but I imagine you'd need a custom reducer flange made for the cats. Which means later on you'd need to re-weld the cat part.

thanks for the info
i'll have to price a reducer and maybe just wait a few more weeks until i can afford the header and everything else.
