I searched, but you can't search for "hp" because of the 3 character minimum.

Alright, so I'm looking at buying the hp header, but just the header, not the downpipe. Will I get gains from this? I have an EX automatic. Will it directly bolt on with no modification? Will my check engine light come on? What's the difference between chrome and ceramic? It's legal, right, since I'm keeping my stock downpipe and cat? Was it hard to install?

Alright, thanks. If anyone has done this setup please post your gains.

for just the header, may be 1-2 hp. but more with the downpipe. I don't think install is that hard. my friend did it for me, he said it took him 20-25 min (i didn't watch him, i was at work). if you are going with just the header, NO the CEL will not come on. if you are going to replace the downpipe, that i don't know. i don't have a after maket DP. anyway. i hope this help

Doesn't the downpipe make it illegal?

the whole thing is illegal its made for off road use only. in order for it to be legal it need to be c.a.r.b exmpt like the dc header.

Hmm I heard just the header portion by itself was legal.
