Sounds like a great idea and I would love to do a tgv delete model as well but for now we really want to get our "flagship" model out there. Besides we're trying to keep the cost down due to a more broad market. But like I said before we would love to do more custom fitments. But I think after we get the manifols done then we'll make the tgv deletes. We try to keep the prices as reasonable as possible without sacrificing any quality. You don't have to worry about our manifolds cracking, all of our 7 second cars have seen no problems yet. Yes they are streetable, just a little loud.
