FAQs

Is this system compatible with the factory valving system?

No, the valved version includes its own standalone valved muffler and remote controller.

Do I need a tune to run this exhaust?

No tune is required. This is a direct bolt-on catback system.

Does the titanium version sound different from stainless steel?

Yes, titanium tends to produce a higher-pitched, sharper tone, while stainless steel offers a deeper, throatier sound.

Can I switch between the valved and non-valved versions later?

Swapping between versions would require changing the rear section, as the internal designs differ.
