Right now the car has kooks lt's, jdm catted h and a magnaflow catback. Unfortunately the h pipe developed a hole in it (in the converter) and the car sounds like poop right now. I like the sound of the car w/ the converters, it's not overly loud...the car is tuned already, etc. However the price of catted mid pipes is more than I care to spend. If I swap it for an o/r h am I able to still drive the car w/o a retune? I will get another retune over the winter or before I pull it out for spring but my work schedule will not allow it to be done right away. So if I bolt on the o/r h and still decide to drive the car (and not exactly race it) will I be ok?
