that's what i want to know. somebody must have a stock wrx header collecting dust i can hack up and weld back togetherthat's sweet, that is some serious rumble from the n/a 2.5i. wonder how me modified the header to fit.
i think i originally figured out it would work if i had the cats off a 02-05 rs/ts. i just want rumble for cheap and i don't have the ambition to find partsbolt on the wrx manifold, then bolt your cat to where the up pipe would go.
