Gonna catch hell for this, but exhaust on any modern car.

You don’t need an imported catback from a legendary brand. If you’re looking for power, look elsewhere. If you just want to change the sound a little bit, have a good shop weld in the largest Magnaflow mufflers that will fit.

Magnaflow’s quality is top notch, and you’ll gain just about as much power as any of the big brands. Which is basically none.

Leave the stock pipes and resonator.

...And don’t put a test pipe on your daily driver, you jerk. That’s selfish and dumb.
