Due to cost I would stay with stock. I dont belive they help until your over 400hp. I'll sell you a stock one.

For stock one call your local Frieghtliner dealer with engine# I bought one 4-5 yrs ago for $175,then grind all the slag/imperfections(help remove hot spots) from the casting, since then I've put 500k plus on this manifold.:2cents:

Geno's has ATS for 470.25 three piece and a BD three piece for 508.25 these are pulse flow this helps to spool up the turbocharger faster. good luck
