Be Careful Quoting Patrick Swayze.
Patrick swayze's been crap in some movies, but I will without a doubt roundhouse anyone who talks smack about roadhouse.
Intake ports are 44mm I think, exhausts are quiete decent to but not ridicilious should be nice n torquey with the single.
The header wrap cut's engine bay temperatures by upto 40%. If you want to be lazy you'll be replacing the extractors every 4-5 years. And with how cheap decent second hand extractors are it's not the end of the world. But I plan on taking them out once a year wirebrush them down repaint them and rewrap them. You can use the same wrap each time and you barely use a can of flame proof paint. They do hold the moisture in and people whinge but in my opinion they're well worth it, especially with side port.
I will also be using a bent aliminium piece of plate with a slight bend bolted onto the header bolts and going flat then bending slightly down. That and the special heat shield honey combe stuff. It'll be attached to the aliminium shield, some people just use the honeycombe stuff but it's not rigid enough for me.
