I read the 1st sticky in this section about exhaust. I am only providing a few pics and sharing what I did,.. My 01 v6 had a cracked "replacement" manifold. It looks closer to a "log" style as opposed a typical shorty header. I have previously done this before a while back on a 98 v6 I had built. Any way, new to me 96-98 headers($40 shipped from a "corral" member). I welded around the outside of the tubes for each port, then ground out the inside weld. I do not have that pic, sorry lol. But just imagine it
.. Anyway the 2 pics I do have is from the stock cracked takeoff manifolds. The i.d. of the collector is 2". That is tiny... The i.d. of the 96-98 shorty is 2.19" , I basically just "cleaned out" the collector and its opened up to 2.25"... Now for $40 plus a little time, I believe I have something just as good as a shorty with out spending $150. Plus, I like the idea of using junk and improving it so-to-speak.
