I have DC sports 4-2-1 headers on my B16. And i was told that the JDM ITR stock headers would open it up a lot more. Anyone know if thats true?

 

It well give you more top end because it's a 4-1 and also it's a 2 1/2 inch outlet......

I think the Jdm itr header looks better also it give you that stock look.......

 

you only have one Header, and yes it would help

 

heres a good reason why a dc 4-2-1 header is crappy:

 

the only problem with the 2.5" collector, you have to get a new cat/testpipe or modify the stock one

Which is no problem at all.

 

how much better is a 2.5 collector going to be if its goign into a 2" exhast.. ?

 

the itr header looks way better then the dc .

thats why you run a 60mm exhaust

 

thanks for the input. but the cat or test pipe is no prob cause i don't have either one. just straight 2.5" back to the muffler.
