Alritey so I am basically buying some bolt on parts for my new motor (b18c1) into an 5th gen hatch. Anyways basically Im adding along headers/intake/exhaust as I dont feel the need for more power - rather focus on suspension and brakes afterward.

Anyway my thoughs for my setup are as follows : JDM DC/or JDM 4-1 , Carsound Cat (good choice, what does it need to bolt up to the JDM 4-1's?), Apex'i WS Exhaust.

now my main question is that when u buy the WS exhaust how will the piping attache to the carsound cat as its 2.5inch in diameter, does anything need to be modified. And if so what?

Also for intake - dont really feel like running an AEM, as i know alot of b18c1 hybrids into an EG (EH) have problems with it. What kind of modification wuld it take for a comptech ice box to fit in or what OEM airbox should I use..??

thanks all
