Do a you tube search for 5.0 Exhaust :
Listen to quite a few to figure out what you want.
Some Ideas to hash:
a.) Mid-pipe -
Do you like the sound of Catalytic Converters or not? (No cats is known as Off-Road and is not legal) While choosing no Cats will be louder you will find it will reduce your bottom end ft lbs of torque while increasing you top end horsepower. Running cats will increase your bottom end torque and lower your top end horsepower. These differences are very slight.
Will you go with a X-style pipe or H-style Pipe. X-pipe tend to sound somewhat more exotic in the 5.0s. Most people find the H-pipe to be the pipe of choice. With a X or H you find slight variances in horsepower/torque ratings.
This is basically a decision on how loud would you like to go or what sound exactly do you like. Once again watch some sound clips and see what combination you like.
Although not usually a first mod for some, headers do help with sound and power and are still fairly easy to replace on the SN95 5.0s when compared to the 4.6s. Your options are Long Tubes, Mid-Lengths, & Shorties. Most find that Long tubes and Mid-lengths make the most power increases when compared to shorties. Shorties will allow you to keep the same stock style mid-pipe setup while Long-tubes and Mid-lengths will require a matching mid pipe or custom mid-pipe. Long-tubes & Mid-lengths sometimes require modifications to the steering knuckles, starters, and a few others.
2.) Cold Air Induction/Ram Air Induction
Cold air induction (CAI) are the air filter and tube inlet that feed your intake air from inside the wheel-well. Ram air kits usually stop before going in to the fender-well. Debatable are the pros and cons of each.
