Well after taking in to account all of the advice I've been given from the forums. I've decided to go with an AEM Short Ram Intake and a twin loop muffler for my civic. I am wondering what size piping I should ask for when redoing my exhaust.

Thanks,

I would not go any bigger than 2.25in if you are running a stock setup. 2.5 if your running a turbo at around 10 psi, and 3in if you run over 10psi.

dont know what your setup is but this is what i found to work good from my mitsu days!

 

2.25". Or 2.5" works if you plan on running a mellow boost setup in the future
