The Vibe & Specs
- 4.5” High-Flow Flow Design: Maximizes exhaust flow and eliminates backpressure so your turbo spools stupid fast.
- Built-in Heat Shield: Shields your engine bay from brutal radiant heat so you can do pull after pull without heat-soaking your intake.
- Raw Sound Upgrade: Unlocks aggressive cold starts, deep exhaust notes, loud turbo whistle, and heavy burbles (when paired with a Stage 2 tune).
- T304 Stainless Steel: Precision TIG-welded, corrosion-proof, and built to take absolute abuse.
- OEM Fitment: Direct bolt-on for factory or aftermarket exhaust systems—no sketchy custom fabrication required.
