i think im the only 1 thats swapped to a 1.8 tubular steel manifold. just cause my 2 piece cast one cracked, and hyundai wouldnt fix it even though theres a recall.
there is some work making it fit, theres no primary o2 bung on it. there primary on the older 1.8's are where my secondary is, so i had to drill a hole, and weld in a new 02 bung. and also its about 8 inch's to short to match up to the rest of my exhaust, so i had to make an extension. and it wasnt a straight on deal, so a basic chunk of pipe wouldnt work, it has two slight bends to meet up with my exhaust.
i can take pics if needed. there really wasnt any gain i noticed, just less of an exhaust leak after installing it....
