Every GT4 RS owner wants a different sound, so Valvetronic Designs makes this system in three setups. This listing is the rear section only, with a large cross-section X-pipe for a refined, exotic tone. Everything is Grade 5 titanium, tipped with burnt titanium.

Features

  • Grade 5 titanium, 11.8 lb lighter than the factory exhaust
  • Large cross-section X-pipe for tone
  • Vacuum-actuated valves with controller for factory-style operation
  • Burnt titanium tips
  • Precision TIG welds, 100% reversible

This rear-section SKU uses an X-pipe to shape the naturally aspirated flat-six's sound. It is the rear section, not the complete over-axle-pipe bundle or the separate header configuration. Grade 5 titanium is the specified material, with TIG-welded joints and a reversible installation so the original exhaust can be restored.

The GT4 RS and Spyder RS use the factory valve control with this system. Retaining that OEM control is part of the installation rather than an optional sound setting. The GT4 RS and Spyder RS share this rear-section application as identified by the manufacturer page and its part number.

Images are from the manufacturer product gallery. That gallery covers other material, engine or configuration choices as well as this SKU; the part numbers and included items below define the product supplied.

What is included

  • Titanium rear section with valves and controller
  • Burnt titanium tips

Part numbers and configuration

  • POR.GT4RS.VSES.TI - Rear Section only / Burnt Titanium Tips.

The rear-section choice retains the over-axle pipe purchase as a separate decision, while the included burnt titanium tips finish the rear of the car.

Specifications

  • Material: Grade 5 titanium
  • Valves: vacuum-actuated with controller
  • Weight savings: 11.8 lb versus factory
  • SKU: POR.GT4RS.VSES.TI

Fitment notes

  • Rear section only. Over-axle pipes and headers are separate configurations. GT4 RS and Spyder RS installations reuse the OEM valve control.
