Hi Driven Photography.
About the only way to significantly increase power by modifying the exhaust, is to replace the header with one that doesn't have a cat. Therein lies the problem with staying smog legal in CA.
Now, you can change the cat back or axle back portions of the exhaust system and get some cool sounds, but no significant power gains.
The "simplest" way get some sounds and a small increase in power is go with a cat or axle back system, a freer flowing air filter and a tune (optional).
