hi all can anybody help i have a 2003 4jx1 all recalls done vehicle runs fine altho feul consumption has increased to about 550km tank last couple years. i recently upgraded to 3inch dump with 2.5 inc mendral bent exhaust no cat . vehicle now has no dead spot at low revs and turbo seems to hold better at high revs, very happy with mod havent had long cant tell yet wheather it has helped with fuel consumption.my problem is now i have unbearable fumes from exhaust ,realy eye stinging stuff. these fumes were there b4 mod but not to the extent they are now. i relize no cat not helping prob but i think fumes are exessive and linked to higher feul consump. im taking to my local machanic who has tech2 any body have any ideas what he should be looking for thanks in advance for any advice vehicle isnt smoking from exhaust much if at all
