I wont say that i was wowed by the MBRP kit i got, the instructions were lousy and did not match the parts i received.... however, it does all fit, work, and is nice and rigid once installed so i really cant complain, especially at the price point its at. I opted for a muffler on mine and dont seem to get nearly as much drone on the highway as others have commented on from a straight pipe.

Unless your producing tons of power where you have the exhaust flow to utilize the larger pipe, there is no difference besides maybe the tone. the 5" is more likely to drone on the highway also.
