Re: question on headers for 4wd T100
I have a 96 4X4 WD with the TRD headers. Have replaced the joint seals twice to stop the leaking at the joints. Appears to help the HP at the top RPM's (above 3500 RPM). Doesn't appear help much at the bottom end. Hope this helps. If I had the 98 model, I would have gone with the S/C with the 7th injector and been done.
