ok, thx for all the info!!

 

just one more question, isn't the stock header same as the aftermarket ones, they both shaped almost the same, and they are both 4-2-1.

thx

 

but aftermarket headers provide smoother flow with less restriction and weigh a whole lot less.

 

oic!! thx!!!

i saw this header on ebay, but they only accept money orders or cheques, is that safe?

 

what is the differences between a stainless steel and Ceramic?

thx

 

Hrm, that's weird, I just bolted up a high-flow carsound cat, and RS*R exhaust on my 99 EX, and it goes like this exhaust header, cat, resonator, "L" pipe, muffler.

But you're saying on your 98 ex (same car) that the resonator is inbetween the header and cat? I think that shit's ****ed up bro... You're o2 sensors would be all ****ed...
