Thread: Best exhaust system for 3.8NA

All stock with Borla mufflers is a nice set-up.

The Walker stock replacements would be your best bet. Dynomax Super Turbo's are very quiet as well. But the resonator is where the tone will really help out. I ran a stock style resonator along with headers and no converter with no mufflers. Hardly any drone (shockingly) and sounded decent enough as well.

But in the end it's a 3800. Keep it quiet and address the issue, which is not the catback.
