You ever heard the term never ass-ume because you'll make an ass out of yourself hehe! That's a RMF header with 2.5 inch merge collector coated on inside and out. You lose absolutely no accessories with the header. $750 plus shipping. Randy Moore Fabricating and I recommend him for all your custom header needs. Made 17 more hp than a DC sports with no tuning. No 6 month waiting list like smsp and hytech either. Pretty wild header design huh! Also there's no such thing as a turbo header, you mean turbo manifold right?
