After chasing the vendor (Andysautosport) then the manufacturer around a bit..DC shipped me the correct front header and the install went off without a hitch.

I also did the APEXi catback and a test pipe at the same time. The car was pretty loud but the power increase was significant (seat of pants dyno).

After a couple weeks though I decided the raspiness and volume was a bit too much so I ordered a new OEM spec Cat and replaced the test pipe. Much better sound, maybe a tiny drop in power delivery.

I added a UR crank pulley shortly after which really improved off-idle response with the reduced rotating mass on the engine.
