I would choose the 2.5" kit based on the exhaust flow requirements of your motor.

the 2 1/2" kit with 3" tips is the largest that looks good on that style IMO

The 3" system is only recommended for high horsepower applications, such as supercharged engines. The 2.5" system is all you need.

2.5" system

2.5" system, then do whatever you want with the tips. I had the last 12" of the 2.5" system replaced with 3.5" tips.
