There's not much if any measurable gain from a bolt-on exhaust system or muffler. Gotts mod = no gains.
Do intake and cat-back with a Tune if you'd like gains you can feel.
And I'd bet dollars other than a True cold air intake (as opposed to some filter in the engine compartment at the end of a tube) won't show performance gains one can measure or notice.
