im picking up some headers..im debating on greddy 421 or DC..421..

 

go with the 1 that makes the LEAST amount of Horsepower that way u won't be as fast as me!!!!! lol

 

i havent heard much about the greddy's, but i have DC 4-2-1 and have had DC 4-1 and i definetly like the 4-2-1 better... it gives it a deep sound and a pretty noticable power difference-especially up top... the 4-1 looses too much low end for me.. the only defect i've ever seen is leakage around the very edge of the weld on right out of the block.. and that was easily patched up... again, i havent experienced greddy but i strongly recomend DC

 

I have the Greddy stainless. I like it, it seems to be of a better built quality then the DC.

 

dc jdm 4 to 1.

 

lol, i didn't notice any new sounds. DC 4-2-1 is a nice header...gives lots of mid range. dyno proven power seen on a stock gsr in a header test. and just a little bit top end.


better than all of them.
