Strup Ceramic vs Weapon-R Stainless headers.

So I'm trying to decide on the Weapon-R 4-2-1 stainless headers + S-pipe or the Strup Performance ceramic 4-1 headers.

For those who don't know the difference of the various things posted above.

Ceramic (done right) dissipates heat and doesn't discolor.
Stainless acts like metal but doesn't rust as easily.

4-2-1 Headers start with 4 pipes, reduce to 2 and then to 1.
4-1 Headers start with 4 and immediately reduce to 1.

Do your own research to figure out which you'd prefer but the gist of it is this. A 4-1 header has more gains on the outsides (top end and bottom end) and a 4-2-1 has less gains but they're across the spectrum.

I'm leaning towards the Strup. The issue often had with the xB headers is heat within engine bay. The ceramic headers cool quicker to help this. They also will run cooler which will draw the heat/exhaust from the engine to allow for more gains in the equivalent, non-ceramic version. The Weapon-R however come with an included s-pipe which essentially negates the power/performance argument unless the Strup is eventually mated to a larger diameter s-pipe as well.

Anyone else knowledgable on engines is welcome to speak up if they feel I've missed something.


(Long story short, trying to decide between the two header kits and that's as far as I've gotten so far.)

Guess it depends on your goals. It would seem yours is just to have a header. Mine was to improve my low to midrange rpm performance. Unfortunately, I lacked the coin for the 4-2-1, so I settled for 4-1 (with other offsetting mods). However, if your goal is upper rpm HP, the 4-1 is an effective choice :)!
Id love to get the weapon r with the s-pipe. I hear its a great sounding setup.
