Toyota Yaris GR Turbo Back Race Exhaust — 200‑Cell Race Cat with Repackable Rear Silencers (Full Decat Option for Motorsport Use Only)
Designed for maximum flow and race‑ready sound, this turbo back exhaust system replaces the factory rear section to unlock power, reduce weight, and sharpen throttle response on Toyota Yaris GR Turbo. The system pairs a high‑flow 200‑cell race catalytic converter with repackable rear silencers. For dedicated track or competition vehicles, a full‑decat option is available (for motorsport use only).
Key Features
200‑cell race catalytic converter: Optimized for high exhaust velocity and reduced backpressure while retaining a catalytic element suitable for many race and aggressive street applications.
Repackable rear silencers: Multi‑chamber, high‑flow mufflers constructed for easy disassembly and repacking. Tune sound level and tone to preference or service for long life.
Full decat option (motorsport use only): Completely removes catalytic element for maximum flow and weight reduction. Not compliant with emissions regulations for road use.
Mandrel‑bent tubing: Smooth, constant‑diameter bends maintain flow characteristics and minimize turbulent loss.
High‑quality materials: Available in 304 stainless steel for corrosion resistance and longevity; TIG‑welded construction for strength and clean appearance.
Fitment: Direct bolt‑on to Yaris GR Turbo rear section mounting points; designed to retain factory hangers where possible for secure installation.
Sound profile: Aggressive, race‑oriented tone with strong turbo spool and mid/high frequency character. Repackable mufflers allow control over loudness and resonance.
Weight savings: Lighter than OEM rear assembly, improving handling response and overall vehicle mass.
Materials & Finish
304 stainless steel piping and muffler shells
200‑cell high‑flow race catalytic element
High‑temp packing materials for repackable silencers
Installation & Maintenance
Direct bolt‑on installation; professional installation recommended for proper alignment and sealing.
Repackable silencers can be serviced to restore tone and performance. Replacement packing sold separately.
Full decat option should be used only on vehicles intended for track use; removal of catalytic components may require engine recalibration or supporting modifications (fuel, engine management).
Ordering Options
Performance Notes Expect measurable reductions in backpressure, a sharper turbo spool response, and a more aggressive exhaust note. Gains will vary depending on supporting modifications and engine tuning; professional tuning recommended after installation for best drivability and to prevent engine management faults.
