I had aquestion will the hx40 downpipe fit the the stock hx35 exhuast housing what do i need to do for a true 4 inch down pipe, Because i was going to buy one but didnt want the small piece of three at the collar and then go to the four inch. thanks for the help!

 

No the hx40 downpipe will not fit the hx35. To my knowledge there is no way to have a true 4" exhaust without trading up to a different turbo because the stock hx35 turbine housing outlet is only 3"(correct me if I'm wrong) making the adapter necessary.
