Product Description
Every element of STILLEN’s Nissan Z Cat‑Back Exhaust is built around one goal: unleash the VR30’s full potential without compromise. We start with buttery‑smooth, mandrel‑bent 304‑grade stainless steel tubes—carefully TIG‑welded to 2.5″ flanges—to preserve maximum flow and longevity. Next, our CNC‑machined X‑pipe merges left and right banks into a 4″ cross‑sectional channel that rescues lost pulse energy and banishes that lifeless, turbo‑flat note.
Street Series: Slip into refined menace. Twin mufflers, polished to a mirror finish and welded on bespoke machinery, tame the roar into a rich, throaty burble at idle then blossom into an athletic growl under throttle. The result? A daily‑driver exhaust that feels bespoke—never boring.
Competition Series: Want your Z to bark like a demon unchained? This straight‑pipe setup strips away mufflers, letting the VR30’s turbocharger melody resonate in its rawest form. It’s unapologetically loud, endlessly captivating, and surprisingly cost‑effective for a fully engineered performance upgrade.
Choose from three tip styles (polished stainless, heat‑bled burnt finish, or carbon fiber) to dial in your visual statement. Then, lock everything in with STILLEN’s signature cross‑brace, engineered to cradle the exhaust through track days, canyon runs, or daily commutes.
