I got this header for my gsr civic and changed my mind. think it would be a worthwile upgrade over a '92 ls stock header on my b20 tegra? or just sell for $$, or get a different header? I'm not worried about fitment here, just power gains

Any ls -->gsr header experience?

also curious about a larger mid pipe..

i'm trying to figure out what technicalities are involved when they design these headers.

Are these headers designed for their respective engines technical characteristics? Or are they simply just better or worse flowing, regardless of the engine its bolted too.
