4' exhaust and hx-40 adaptor ??
hi
who here has used the hx-40 adaptor and installed a 4" exhaust system ?
is it worth any more performance to buy the adaptor and use the 4 in downpipe also rather than a necked down version for stock turbo ?
is it cost effective for power and fuel efficancy ?
how much extra did it cost ?
thank you !

Think about it this way.. ull actually either have a 2-4inch down pipe (restrictive and adds heat) or you can have a true 4inch down pipe which can also hlep spool up and bring the heat down. And if u plan on changing turbos the stock elbows going to be gone anyway
