I read previous threads about SMSP, HYTECH, DTRFAB, AN-R, Etc.

Too much to read actually.

I am looking for a header, one of the above, for my new motor being built, side exit type. I am willing to wait the length for completion since it is custom made.

It seems that there is pros and cons for each header. I would like to know which would be the best in overall quality, worksmanship, and performance gain.

My motor is 1.8L, running from 12.5:1 to 13.0:1 compression, pnp head, Toda Spec B or C cams, 310cc injectors, Skunk2 intake manifold, 4.785 trans with ATS or Toda cross gears, etc.

Thanks for you inputs.

 

Look up the header dyno test! its got dyno comparison of the most popular header's outthere!

 

yeah, i belive titan motorsports did the header test. best bang for the buck was the JDM 4-1 DC and i'm just trying to think if it was hytech with the overall best numbers............
