Re: Ceramic Headers vs. Polished

Polished or chrome work just like painted headers except the chroming will usually turn blue after their heated up, ceramic coated headers keep more of the exhaust heat inside the tube, which in turn keeps exhaust gas velocity higher and the engine bay cooler. Other than that and the cost they are pretty much the same.

Re: Ceramic Headers vs. Polished

as stated above, ceramic is all about the heat but I would go with some non ceramic headers and wrap them in tape I just love the look but its all personal preference too

Re: Ceramic Headers vs. Polished

I personally am all about performance, so a properly working exhaust system is key for me. Ceramic will reduce underhood temperatures (which is good for all kinds of things) and because it keeps the heat inside the tube (as stated above) it will help exhaust gasses maintain their velocity through the exhaust system. This is important for a few reasons. First off, if your exhaust gasses are flowing at a higher velocity, they are creating a greater vacuum behind them which helps draw more air into the combustion chamber during time the intake valve is open at overlap (scavenging). Using headers also helps your exhaust pulses line up better when exiting the head so they're not running into each other when they meet in the exhaust header. This helps flow dramatically, especially in correct sized headers, and especially in ceramic coated headers that keep heat in. On top of that, wrapping exhaust wrap around the header (while some may consider this overboard on a ceramic header) reduces underhood temps even further, keeps even more heat in the exhaust system which helps maintain velocity, and protects the header when properly wrapped from rust, road grime, rocks, debris, etc. Hope this helps!!

Glad I could be of help!! If you need help with sizing or long tube versus short tube lemme know and I'll help there too. I have a thread already posted about exhaust and what my findings were if you feel like checking it out. Later bro!!

Thanks alot... And I'm prepping for supercharger and I read that long tubes are the better for them... And when I'm get them is it true that I'll have to drop my K-member?? I was gonna get an aftermarket one but is that a bad idea??

Re: Ceramic Headers vs. Polished

you dont have to drop the k-member, but it will make it alot easier. and swapping to an aftermarket one is a good idea since you will drop weight in the process.

Re: Ceramic Headers vs. Polished

My thread is for a 2000 gt.. i'll have to do some spec looking up for your '12 V6 and crunch some numbers for specific sizing if that's what you want.. as for short vs long here's the low down. Short tubes are considered a direct replacement for your stock manifold. You'll notice an increase in fuel mileage, throttle response, power, and torque. Equal lengths are even better at these bonuses. Many factors come into play when choosing shorty, long tube, or even tri-y (4 to 2 to 1), headers such as:
1.) Vehicle weight- if heavy (3000 lbs or higher) long tubes will give you more bottom end tq and hp, but high RPM will suffer. If light, it's the exact opposite, but it also depends on proper primary tube sizing. Basically, Light vehicles = shorties with High RPM, but lacking on the low end.
2.) Altitude- as you go up in alt. go with long tube headers no matter the vehicle weight. This will help increase throttle response.
3.) Gearing- low numerical numbers (ie. 2.73:1) in the rear axle- go with long tubes. If high gearing like 4.55:1 or whatever.. go with a shorty.
4.) Compression ratio- it's the same as altitude. Low compression engines benefit from long tubes. High compression engines benefit from shorties.

When it comes to sizing there are some calculations that are needed to determine correct primary tube size on your headers. I'll try to figure out how to link my thread as an example of what I've been trying to figure out. The thing about my dilemma is I'm having a hard time finding accurate info to be able to use for my calculations. If you read it you'll see. Hope all this helps!! Lemme know if you would like more as well!!
