I hear the JDM DC 4-1 hangs quite a bit lower... I did a rough estimate with a tape measure, but it was hard since one of the headers was already installed... It came out with the JDM being an inch lower, but like I said, it was hard to measure so I could be completely off. Anyone know the height difference?

Thanks in advance...

 

I would like to know too...

My DC JDM is pritty banged up and was thinking of getting the oem JDM instead.

 

You should really ask this in the civic forum thats what its there for.

To answer your question, the JDM DC 4-1 does hand low on a civic Si. My car wasn't low to begin with and the header ended up having some scrapes. Raised my car and problem fixed.

 

It will hang about 3/8" lower on the B16A engine than a B18/B20. The lowest part of the tubes is at the bend going under the pan. The tubes then look like they turn slightly up going back to the collector. At least this is how it was on Eric Rosen's H1 Civic.
