Switched testpipes question

[stormtrooperx]

Hi guys,

I switched my testpipe to a 1 piece testpipe/downpipe combo. The o2 housing is still stock. I was tuned for the testpipe only not the little downpipe piece.

Would I need a retune or should it be fine? I'm going to assume I should be fine, but better safe then sorry.

Thanks!

you will be okay to drive, but you will want to get-re-tuned by your tuner.

it wont make that much of a differences on the tune since you haven't change your o2 housing. you should get that change then re-tune it..
