Has anyone seen an aftermarket 348 header availible ?
I'd like to know the answer to this too. Someone posted last year how his company was going to build them (MVPEurosport or something like that), but there has been no update. I'm doing the 30K later on this year, plan to put in hyperflows and it seems like it would be a good time to do headers if they existed.
I had a discussion with Kevin, of NA Performance last year, about getting them made. The deal never fell through because not enough people showed interest. When the time came to put up the money not many people stepped up to the plate. I'm still looking into this for the future though.
