ARH LT HEADERS NO Cats problem

[UNSTOPABLE]

Guys i have a problem.... when i go at 50km/h in 4th gear at cruise speed, feel some restriction to back gear (i have to push my foot a little more an more to gear down) .... what do you think..???? Some told me than is the O2 rear sensors....matt from moes told to remove the 87mm TB (because is so much air flow) other says have to disable MDS.... just rigth now have a check engine light off, but i think the problem are the spacers under the O2 rear sensors......Thanks and i listen your comments..!!

HEMIFEVER TUNE Maybe clean my problem.....!!!!

when you add long tubes you need to tell the computer that there is more air moving in and out of your motor. maybe with a custom tune you can get this fixed. i dont think anyone has had problems except for running them with no cats and the engine light comes on but HF can turn that off.
