Most affordable ceramic coated headers and y-pipe my friends on a 02 WS6 budget build and wants to get some headers so he's looking at the pacesetters with the jet hot coating. he also wants his y-pipe jet hot coated and he found out the hooker 3in ORY can come like that and so he's wondering if there will be any problems with installing them if he decides to go with them??
There might be a problem and there might not. Anytime I do a Y-pipe install I always expect it to be a huge pain. Y-pipes will always have a wierd fit due to the difference on different cars. It is hard to find a Y-pipe that is the cure all fit all....even on 1 kind of header.

now, why coat a y-pipe? it won't affect your engine bay temperatures and it's useless for looks. there is absolutely NO POINT to getting it coated. it does nothing but drain your wallet. you'll see no better performance out of it. to the OP: tell your friend to save his money.

You missed the other benefit of ceramic coating.....to keep the exhaust temps up. The more heat you can retain in the exhaust system, the faster it travels through that system....thus improving exhaust velocity which means more power. Not saying you'd see a huge improvement in a coated y-pipe over non-coated, but every little bit helps.

That velocity argument applies for headers, where there is defined pulses amongst the tubes at the merge collector. This is why larger tubed headers cost power on bottom, with gains up top, where pulses are not defined enough to produce scavenging, and increased area produces more power.
Here's my thoughts on the rest of the system. Flowrate is dependent on pressure drop and flow area. An engine needs to push the exhaust gasses out, which it will do no matter what it has to go through. Since the end is always 14.7, the only way to cause a larger pressure differential is to increase the upstream pressure. This increase in upstream pressure costs us power considering the motor is the "compressor".
Lowering the temperature of the gas increases the density, causing the same volume to include more exhaust gas. This denser gas can be forced through the same pipe, with the same CFM, using LESS differential pressure. This is going to save us some power that we would normally use to compress the gas.
A prime example of this is turbo piping. Ever wonder why turbochargers have the largest downpipes as will fit? Larger pressure drop, as soon as possible, increases efficiency.
....but I've been wrong before...
