Im taking it in for new exhaust tomorrow and have a few questions.

Will hi-flow Flowmaster type exhaust, and K&N air filter help the 6.2L like it will a gas engine? It already has duels, but what type of exhaust, muffler, and air intake do you recommend for best performance?

Im not going to do anything extensive like a turbo, just the exhaust and intake for now...unless there are other inexpensive options you would like to share.
