whats up guys,

i got a jdm h22 with j's racing intake and 2.5 in exhaust straight back to oval muffler,

my problem is the selection of header

i have a AN-R header that i put on (not happy with the results, running very lean, and ground clearance is horrible, already bent halfway in, that could be the problem y its not impressive), i lost power. i know cause i lost to cars that i smoked b4 with my stock header, i know tuning will solve the lean but will the gains be worth it on a stock motor for now?

i have the stock header, pullled veryyy nice but i want something bigger and a lil bit more power,

i have a dc header, aftermarket header, but don't know if i'll get that power i want, maybe with 2.5 in collector mod?

i have a jdm aftermarket header(dunno which type just says jasma on it) which seems like it has very big primarys, only problem is i odn't have a downpipe for it..

i don't know what to choose..........

can i fix the anr header by cuttin the downpipe and makin another one???

can i add a downpipe to the jasma headers???

is dc not worth the time and effort??

is stock good enough???

my goal is for a strong mid-high power band(which anr says will improve but failed)
=[[[[ please help =]!

i've tried researching on dynos but couldn't find anything =]

p.s. a lil off topic, but why is my msd box blinking oO please help!

i posted this in the tech forum but got no help, hoping someone here could help me out =]

 

I would say a header upgrade is a waste of money unless you get a custom header like RMF or SMSP.

 

but i don't have any of those, i got a anr header, but won't get anything out of it unless its somehwat built, for now i'm stock =]

 

i wonder y no one helps oO

 

It seems like people who have the dc header do the 2.5" collector mod and are pretty happy with it. Under the circumstances, that seems like your best option. Hope that helps.

 

thanks for ur opinion! =]

 

tune. if you know you are running lean then tune. maybe you have a different problem and that is why you are losing.

its like me saying my car is slow because of all my mods I Know my car is running rich. no my car is not faster because I didnt tune it after everything.

and I would say dc with collector mod and sell everything else. or fix the AN-r.

how do you know its running lean?

 

JASMA isnt an aftermarket company. its japan's version of a C.A.R.B sticker. it just means its street and inspection legal.

i know its not a company, the actual company is fuji whatever lol the primarys r pretty bralic and the secondaries r the same size as the stock ones, to bad they told bolt up, can i weld on 2 peices of pipes to a 2.5 collector?
