I wanted to know if anyone has the HKS rear section on their civic.
I am planning on going with the rear section and then getting custom piping
from the head to the rear section and installing a high flow cat. Any suggestions or comments
will be helpful.lease:

i have the hks rear section, as well as other members here. good choice i had pics of it but i took them off my gallery. i dont think you need to replace the stock piping because it is good enough. just remove or get a new resonator and get a new cat and you should be fine. get a racing header too if you dont already have one.

Thanks. But wont the exhaust flow better with a custom piping? Also what type of head are you using. right now I am just shopping around for a good price.
