i think comparing a 1.5L Civic to a AV6 is ridiculous.

if you havnt ever seen the civic CX and i think some DX's too (1.5L) the intake is very tiny and im not suprised you didnt find a few ponies on that 60hp slug.

i might agree with the headers, but arent the AV6's stock headers pretty good?

boy i cant even imagine what a PITA doing headers on the AV6 is... :O
