M273 vs M113 Header Selection
Whats up everyone!
I've been digging around trying to find a selection of headers for the M273 engines and it’s proving difficult. Kleeman no longer sells them in the United States and Vivid Racing doesn’t appear to sell them with catless downpipes, only the manifold itself. I understand these have been out of production for a hot minute but I do have a love for this engine and know it’s extremely capable.
My question is, will header choice from an M113 clear the ports of the M273? Or any other engine in the series? I’m sure not. But kleeman DOES offer a tune they claim for +40 horses. I would much prefer to put long tubes on the car it just seems impossible to find. Any help is appreciated!
