Bypass valve & Adj. Fuel pressure reg. needed change
 

When you change a exhaust system and wastegate is it good to change the bypass valve and fuel pressure reg. if you still have the org. (16 years old) Don't mean to be a pest, just want to do it right. Thanks, Scott.

Found the answer needed in search. Sorry to waste your reading time. This was the best $18. I have spent on this car. (rennlist sub. that is).
