My 98 Tacoma 4x4 was cat less a egr less. Long tube headers no cat and a muffler off a silverdo. Custom intake and amsoil stage 2 filter.
I was netting 28 -29 mpg when trying. ( rated 20 highway) 24ish with out eoc or trying hard.
But that's from a torquey 2.7 4 cyc truck motor.
Also had 11lbs flywheel. I think 30lbs was stock.
Would I do it again. I dout it.
