deceleration noise
I have had my Corsa Pace exhaust for a few years now, paired with TPIS headers and Random Tech super flow cats and X-pipe. The X-pipe got rid of the crackling and popping. For some reason, recently the exhaust started to have excessive crackling almost like backfire when I left off gas, however, the car runs great. What could have changed or causing this?
Has anyone ever changed their air injection check valves? If so is it easy and or costly for parts?
Any insight would be appreciated.
Thanks
Marc

Marc,
I replaced the bank-1 check valve last weekend. The part was $9.99 at AutoZone. I believe the bank-2 check valve is behind the intake and it must be removed (a slight Pita).
