FAQ

Will this exhaust affect my vehicle’s emissions compliance?

The HS08STIGTP is a cat‑back system, meaning it replaces the exhaust components after the catalytic converter. It does not alter emissions control devices, so it remains compliant in regions where the catalytic converter is retained.

Is professional installation required?

While experienced DIYers can install the system with basic hand tools, we recommend professional installation to ensure proper torque specifications and fitment, especially for the rear muffler and tip alignment.

How much power gain can I expect?

Owners typically report a modest increase of 5‑10 horsepower and improved torque across the mid‑range RPMs due to reduced back‑pressure, though exact gains vary based on engine condition and tuning.

Can I use this exhaust with a turbo upgrade?

Yes, the HS08STIGTP pairs well with turbo upgrades. The increased flow capacity helps accommodate higher boost levels, but a professional tune is recommended to optimize performance.

What maintenance does the polished finish require?

The stainless steel finish is low‑maintenance. Periodic cleaning with a mild automotive soap and a soft cloth will keep the shine. Avoid abrasive cleaners that could scratch the surface.
