As you can see, there is a lot more power to be yielded.

Those are amazing numbers for b series standards....

Also I was told that a type S motor (k20a2) tuned with K pro on the same dyno with 4-2-1 DTR open header made 216WHP TUNED !!! Tuning was done by
DnR Performance.

how much does the 4-2-1 dtr header go for?

I believe it costs $1250-$1300. Yes, that is a good amount of money, but these kind of headers open up a new door to k series performance that we would had never seen in the RSX chassis. Reason being the limited amount of space the RSX has for the header.

Take a look at the TODA RSX k20a header.

Now look at the 4-2-1 DTRfab

Although I made not a header fabricator, it kinda makes sense to me why the RSX one is underpowered. It is not long enough.
