And as far as the header thing goes… believe what you want, but the designs that make the most power are out there and they are expensive. DTR/SSR/Hytech/SMSP/etc. make a superior product with a lot of time and effort into their headers. Guys stop giving her a hard time. Spacers do give HP believe it or not. NWP makes a Maxima spacer for the TB and the IM if coupled together, they do result in around a 20hp game and 40\* drop in temperature. As far as the header…I have one thing to say to you… GET HONDA GASKETS…PLEASE!!! The ones that come with headers (and mine looked EXACTLY like yours) such big shlong. They burn EASY. My OEM ones are metal, they’ll never burn. I made the mistake of using the ones that came with the headers and had to tear everything back apart. --- _[View the full topic](https://forums.speedlife.net/t/my-07-si/241544)._
