Oh for the love of f***
Ok folks, seriously, it was funny at first but I'm not backing down. I'm not going to change it and that's that. For something that I thought would just be glanced over, soon became the number one question asked to me over the past week. Be it from 18 year olds to 60 year olds...
So, um, what's with the PVC pipe?
So here we go. Back in the 40's and 50's they had these things called hot rodders. They were just like us but broker. They didn't have anything like aluminum or magnesium; they had steel. So add steel with salty conditions when running out on the lake and you get rusty, corroded parts that didn't last a season. So ceramic coating started being used. I mean, hell, if it worked for fighter planes flying out in humid conditions, why not try it on some exahust parts for your car right?
They also discovered that ceramic coating was also a a thermal barrier, thus keeping heat within the manifold or header. There are a number of benefits for this. First, by keeping heat within the manifold, you're going to accelerate the exhaust gas velocity which reduces back pressure and reduces fuel contamination due to reversion. This is a performance benefit.
Second, you'll reduce the surface temperature of the manifold. This means if a person comes in contact with it, they are less likely to be burned and leave yummy skin behind. If there is a component close to it, it will not see as much heat as it would with an uncoated manifold. In addition, not as much heat will be radiated under the hood or into the engine compartment. This reduces the under hood temperature which, again, reduces the temperature of surrounding parts, such as, alternators and starters. It also reduces the amount of heat that can be drawn in through a carburetor, which is a secondary performance benefit.
So there you have it. That's all it is. It's a piece of metal tubing that I had coated white, just like the oldschoolers did. It's not PVC, it's not fake etc etc. And at the next show, I'll be hanging a 4mm wrench from the end just so people can clank it to be sure *winks*
