I need some quick advice/opinions on the best Headers and HFC's for my '09 xS.

FOR THE HFC's:
-My main concern is rasp & drone (I do not want to sound like a civic with a fart can on the back)
(I currently have the Stillen G3 CAI & ARK CBE)

FOR THE HEADERS:
-I am looking for the best product in terms of quality & gains.

I will also be doing the UPREV tune with theses mods.

I am going to DYNO before the HFC's & Headers; AFTER they are installed; & then again AFTER the uprev tune.

SO PLEASE GIVE ME ANY SUGGESTIONS ASAP because I need to get everything ordered and here before the 13th.

thanks for the help

 

headers go fast intesions long tubes.. and for cats go fast intensions high flow cats or resonated high flow cats

 

Long tube headers get rid of the cats. It has shown that headers on this car is pretty much useless. If you still want them, two other companies make them, 5zigen and amuse. As for cats, berks has shown the best gains. Off the top of my head these companies also make them: amuse(both silent and normal hfc's), ark, fast intentions, mxp, invidia.

 

You can't run long tube headers and HFC/test pipe at the same time.

 

I've read nothing but amazing things about the ART test pipes. Extended bungs for the O2 sensors so you don't trip the sensors. Don't have them on my car yet but im decided that those are the ones i'm getting for myself.

 

They dont make the ART pipes for the X model.

Why do you say headers do not benefit this car?
