JDM 4-1 header with a custom 2-1 section(with high flow cat)

[dc5r04]

Hi there,

Today I've jus put a JDM dc5 4-2 header and a custom 2-1 section with high flow cat into my dc5r. Except the high flow cat, the 2-1 section is the same as the JDM 2-1 section. Still using the factory AUDM dc5r catback. Car drives bit different atm, rev seems a bit higher than before---2500 r /60k at 5th gear. Before around 2000 rs/ 60k
at 5th gear. Is that normal? How could i know if the fitting job has been done proper?


Cheers!Tommy

Sorry guys, there is an error on the title, suppose to be JDM 4-2 Section!
