Sad thing they have been discontinue by dc. but there are still folks using such stuff. Anyway another recommended thing is the chikara header and header panel. Im using it for a couple of months and nothing has to question about.New here. Any news on the DC header? Is it true the 1.8 and 2.0 share the same head/bolt pattern? I may get this header for my 2.0 Sentra as I am desperate for a few more hp. I figure I may need to fabricate a mid pipe to make it work on the sentra.
