The only downside I could think off would be clearance; if you have lowered the car, 4" exhaust might bottom out easily. Just a thought.

yeah it has a very deep tone to it, i took out the cat and just ran a straight pipe, muffler was only 90$ i dont buy full set ups because i dont want to pay that much for some chrome pipe.
