i couldnt find a thread about this... but i just needed to know, is a tune required if you get an o/r H? (just getting rid of the stock catted H and putting in an o/r one) also, how feasible is it to retain the stock mid pipe(and cats) to shuv it back in..in say about a years time (*caugh*inspection*caugh*)

thanks

 

I think a tune and tuner would be your best bet or you could get mil eliminators from brenspeed... but not sure if you would get the best out of it without a tune.... and to get it back on dont think it would be too difficult...

 

get a tune to delete the rear o2's and for power(cai)

 

get a tune. you cant go wrong and u wont regret it
