I have a low mileage sedan that I modified with impressive results (butt dyno).

- Motordyne 5/16" spacer
- Z-Tube
- K&N drop-in
- Free-flow axle-back muffler
Car sounds great and feels more responsive - I drive in "manual" mode most of the time. Total cost Canadian was about $700 and worth every penny.

Cheers!

 

A tune now would help. If Art Pipes are in the budget and your emission testing is just for engine codes, that's a great mod.
