Motor is a b20vtec, RS machine pistons, JUN3s, and the essentials.

So I was thinking about modding the collector on my 4-1 USDM DC header for the time being until I get everything together with my hytech rep.

So im debating on either modding the collector(cut off collector, weld a 2.5" extension pipe w/ 2.5 collector, 2.5 exhaust)

OORR

Just keeping my little 2" collector and running the cutout I have(got it in a trade)


I figured that the open header would make up the power loss from a small 2" collector. Any thoughts/opinions/comments? (keep the negatives to yourself)

 

just keep it the way it is till you can drop your hytech in.
installing a cutout would be pretty loud. but if its not a DD then go for it.

DC is junk imo so i wouldn't waste money modding it with that hytech waitin.
