The exhaust flange mounts are in the same arrangement as stock exhaust, thats why they mate so easily. Also the hfc question as far as the differnce in sound....its different from berks to the hfc's from ark because it is resonated. That will change the pitch of the exhaust sound immensely vs a non resonated cat. No cel with berks because of the extension off the cat where you do get cel with ark.
Hfc will cause car to lean out bad so expect some p420, p430, p300, and p2a00. Check my sig for the ark hfc and dual cbe setup....its sick!
