All of our GT350 customer running the Corsa headers have given us excellent feedback as far as fitment, quality and sound. We've posted a few videos of some cars running them on our IG page. (@teamlethal)Getting ready to do some small mods to my gt350r. Steeda motor mounts, headers fro either Corsa or stainless works, and a tune. I haven't really decided whether a cai will be worthwhile or not. I'm really just struggling to decide what brand headers to go with.
