I have a 11.5 comp b20 VTEC in the works w b16 rlz head and pro 2's. This set up is for my daily
and road racing. I was thinking of purchasing the high end 4-2-1 header and it costs $400 plus tax. Anyone have any experience and opinions with this header? Thanks in advance.

 

What header are you talking about? brand?

 

The brand is High End. I once made a post about wanting to buy a high end header and got upset because people clowned on my request. Only to realize there was an actual brand called high end and I felt more dumb than usual.

I never heard of these units.

I had great results using a Buddy club tri Y header as well as the SK2 V1 header, you might want to look into the SK2 V1 its a great bang for your buck over the counter manifold that has been tested and proved to make power. The mega R would be more ideal but its in the $800 range while the V1 is about half.

 

High End makes a nice header.

 

Logic/High End are the same thing.

I have this header, quality is nice and it fits well. has excellent ground clearance also. I have no dyno numbers to back it up, but def felt an increase on the butt dyno when I installed mine to replace a no name 4-1 header, especially on the top end of the powerband. imo it is an excellent choice for a budget header. right now I have it on my full bolt gsr, and will also be using it on my b20v setup once i finish building it. oh and for those that aren't familiar with this header its basically an smsp rep.

 

I've heard nothing but good things about the high end. The SMSP and it are similar and both have proven to make power on B20V's
