no its not built in
no its not built in
not build in, just bolted to
oh....
still, just pop off the header and use the right bit to widen the runner to the stock gasket size. then grind down any sloppy welds on the bottom end of the header.....
thats all i did to mine....gave me some mid-range punch
just buy a header for the d16 off ebay, the porting of the stock header is not going to give you as much of a gain as the new header will.
only problem is there are some issues for the d16Originally Posted by shapinoweno
not as much as people make it seem...if you can weld, you can handle modifying it....plus why waste time modifying the small stock one and gain hardly anything when you can get a better flowing one to modify for 53 bucks shipped?Originally Posted by y2daniel1981
aveosam i sright, anyone with some fab experience can do this. if you got the tools and the know how it is worth it. if not then fine tweak the stock header. but as i stated you are not going to see that much in terms over power compared to the d16 header.Originally Posted by AVE0SAM
or you can try and get Brian's
Does anyone make a header that just replaces the stock manifold and just bolts up to the cat converter? How many people have bought the header from PSC Motorsport and how has it worked out? Any issues with the before and after o2 sensors
there are no headers that will bolt up to the stock cat because the cat is like right there
