I read that the J's Racing Header gives the most gain. I also know that J's has the biggest Primaries and Collector. But does it give the same gains when coupled with all other exhausts? I also know that it works best with a 70mm Exhaust.

What I have is an Apexi N1 Single Exhaust coupled with a berk Test Pipe. Which would be a smarter choice? I really like this combo and am looking for a header to match it. My goal is to have a stronger performance in the Top End. I am not too sure which one would yield the most Top End gains, given my Exhaust and Test Pipe combo. JDM Gurus, I need your help.

a) J's Header
b) Toda Header
c) Spoon Header

Out Of these three, since the Amuse is just too pricey.

Thanks in advance.

get rid of the exhaust and get one of the following exhaust by the names you mention

 

j's racing ... :thumup:

 

apexi n1 isnt a 70mm exhaust, i think its a 63mm...and its 30lbs also i believe...get a new exhaust

 

Keep them coming.. Nice responses. All your input in appreciated.

 

go with J's for most gains, and your exhaust and test pipe combo is perfectly fine. it'll show great gains combined with the header. Ofcourse if you want to make more better power down the line then you would probably want to switch to a 70mm or 75mm exhaut system.

 

I know for a fact it is a 63mm exhaust, I do not think it is 30 lbs though. I remember weighing (is that a word) it, and it was about 17-22 lbs max, but its a single, so it cant be that much.

Thanks for all your input, all is appreciated.

its cast if im not mistaken, thats why it weighs more than most...

now don't get me wrong, i love the apexi n1 series, but theirs alot better available...

 

the apexi n1 is ricey , around my town.. thats all they talk about. they even consider me to get that, over j's or spoon

get j's racing header..

and what exhaust is 75mm , this is unheard of

 

a custom one. mines custom 3 inch and cost me 600 total with canistor mandrel bent. looks nicer, sounds nicer, and gives same gains, probably better then any of these $1000+ systems
