i have broke two dc sports headers with this swap is there any way to keep this from happening

 

what the hell? how you break it?

 

are you running the flexpipe? Not sure, but I always thought that H22s Preludes run flexpipes in the B pipe to prevent breakage at the header flange. I *know* F22 Accords do.

Civics run a spring system at that joint for the same reason: so engine torque/vibration/bottoming out does not break the header as easily.

Cannot answer without more information. How low are you? How are you breaking it? Bottoming out? Can you post pics of the break? Is it denting? Shearing? Breaking at the head? Breaking at the cat? Do you have any kind of flex in the header/cat joint?

I think someone in the vendors corner is selling a hytech replica specifically for H22 swapped civics.
