I know someone has to produce one, but who? I've emailed a couple places, but they say one of two things: our downpipes are designed to bolt up to the stock turbocharger, or that the only 4" inlet is for the 3rd gen trucks. So who out there makes one of these? Thanks.

 

I think Silverline makes one. If it is not Silverline know it starts with a S.
