it does have a little bit of different smell for a little, bit with a O/R pipe, your cars exhaust is going to smell a little worst(in some peoples minds, i think it smells better) , your exhaust will smell a little more potent
Naw, I think that it's cuz you get use to it. I've had an O/R X-pipe with the rear 02 sensors shut off (or mil eliminators if you choose) for 3000 miles...same smell. Although, I've learned how not to experience it as often thru driving style. Keeping the revs above 2K all the time helps alot and above 2500 up hills. Avoid bogging the motor.
haha yeah when it surrounds the car at low rpms and idle its so annoying. i hate the smell. i have a catted on there right now but when i did have the o/r i hated the smell but it was like brand new so i might give it another try.
after i got my o/r x it was pretty strong at first. when i first started it at the garage there was actually quite a bit of blue smoke. after driving it around for a day or so it did mellow out. now there is only a slight smell
