Thread: 4-1 Headers talk!!

This is the only pic I can find. Secondary looks much larger though.

I can see this header make good high rpm power with a proper collector.

Gio made 199.47whp with a stillen header. It is somewhere on here. Car also had quite a sucky tune on it from a some local dude, after that Gio started messing with ecus lol. I remember gio did not like the changes he made to the header it became peaky, but it was just the loss of mid range. I like the stillen header, powerband was nice it just screamed up top, car was faster up top than other ve's with a similar setup.

I have on my PC that magazine article saved as jpgs. If there's interest and mods allow it... I'll post them online for everybody to see. It's from December 1999 Sport Compact Car magazine.

Do et! Im interested in anything that has sr's in it.

Do ettt x 2!

Btw Danilo made 197whp with a pacesetter header on 2.0 cams and a jwt ecu+safc. Just throwing it out there. Underated header imo.

Mods please, if this is not cool, just delete them and don't ban me pretty please?

The great SR20 header test SCC Dec '99

^ Can a mod please ban this guy??

Seriously though, you're cool. SR history is always nice to read about!

Thanks.

Anyone have the specs of ASP 4-1 stepped headers??

Nice one Claudio! that one really cleared up a lot of questions I had about headers
