Im selling my Ram Horn manifold and 3" downpipe from my built B-series Integra. It is 44mm flanged and braced so it wont crack. I had no problem making 544whp with this setup on my Integra. The downpipe looks a little dirty because I tried using high temp paint but it flaked off. I may get it bead blasted so it will look much better. Looking to get $600 obo for the setup. Thanks for looking!
