ok so i saw a post on here about a week and a half ago about how u have to drill out the exhaust manifold threads to put a HX-35 on. is that right???? and can u reuse the stock hardware like nuts an bolts etc....

 

It depends on what year the HX-35 is off of. Most people would drill the threads in the exhaust housing on the turbo out, that way you don't mess with the manifold.
