Hello, wondering if anyone has a lead on headers available for purchase for my 2003 maxima 6 speed manual.

i can’t seem to find anything available for purchase online via ebay etc?

People have stated that any header from before 2003 will fit, as well as some Altima headers, but these suggestions seem vague with little info regarding fitment and or possible modifications required.

if anyone can help me out that would be much appreciated

Thanks

 

Try Darren @ Nisformance, he had a new gen if cattman headers made a while back..... maybe he'll still have a set.

 

95 - 03 Maxima headers will fit but on the 95 - 99 the EGR fitting on the header has to be plugged, Nissan sells the fitting to plug it.

I had good results with older non California 4th gen maxima exhaust manifolds with Warpspeed Y pipe on my 02 6 speed. only issue is that the Y pipe is made for a 4th gen and there aren't any O2 sensor bungs for the secondary O2 sensor. I did a how to on it that makes it way easier to change them out.

another option is modified 02 - 06 V6 Altima headers. I don't see them on eBay anymore but they turn up when you search for them on google.
