there the same , dc jdm 4-1 just copy the jdm 4-1. jdm as an optional heat shield, which u can hide it from cops, and or keep it a sleeper. both has 2.5 collector.

DC looks nicer too because you can get it in stainless steel.

I heard they are almost the same, I was under the impression that the 4-1 will have more gain. But i'm waiting on the header anyway.

Well the DC version SHOULD be better since it has a 2.5 collector instead of 2.25 like the JDM Integra one.
