stock vs aftermarket header primary size?
what size are stock primaries vs all the aftermarket ones, like the ness pipes for example? i'm thinking about building a custom setup using factory headers and want to make sure they're not too small. all i really know is to avoid 08+ with cats.
also could someone post a photo of a set of stock pipes installed without heat shields so i can see their actual position and spacing?
