Porsche 718 Cayman & Boxster Turbo Downpipe & Exhaust System – Titanium - RaggDoll Motorsports

Porsche 718 Cayman & Boxster Titanium Turbo-Back Exhaust System – Maximum Flow, Sound & Power

Maximize Flow, Sound, and Performance with a True and proper 3.5” Turbo-Back Design then axel back can either be 3.0 or 3.5” depending on your preference.

Drop Weight. Boost Power. Eliminate Restrictions.

Transform your Porsche 718 Cayman or Boxster with the RaggDoll Motorsports Titanium Turbo-Back Exhaust System, engineered for high-output street and track builds. This system starts directly at the turbocharger with a true 3.5-inch down-pipe (as it should and is the only correct way whether you have a 2.0L or 2.5L), eliminating factory bottlenecks and maximizing exhaust gas velocity from the very first inch.

Designed for the 2.0T Base, 2.5T S, and 2.5T GTS platforms, this is a no-compromise exhaust solution for owners chasing real power, sharper response, and a raw motorsport sound.

Why This Turbo-Back Exhaust Exists

Purpose-Built for Unmatched Exhaust Flow

Unlike stepped or necked-down systems, this exhaust maintains a full 3.5” diameter through the most critical section before branching into two optimized configurations based on your horsepower goals:

• 3.0” Mid-Pipe Configuration – Ideal for builds under ~500 HP
• Full 3.5” System – Maximum flow for high-output turbo setups

Both configurations delete the restrictive factory Y-pipe and exit through dual 4.0” slash-cut titanium tips, delivering a clean, aggressive finish.

Key Features & Benefits

• True 3.5” turbo outlet to first V-band (no reducers)
• Titanium or stainless steel construction options
• Saves 65+ lbs vs OEM (titanium configuration)
• Optional 3.0” or 3.5” mid-pipe with resonator
• Dual 4.0” slash-cut titanium exhaust tips
• Raw motorsport tone with no highway drone
• Direct bolt-on fitment for all Porsche 718 models
• Custom catalytic and resonator options available

Why Bigger Matters: Exhaust Flow = Power

Real-world testing at 24 PSI confirms what physics already tells us — pipe diameter and continuity directly impact turbo efficiency and horsepower, even at the same boost pressure.

Test Results:

• 3.0” Downpipe + 3.0” Exhaust = 513 WHP
• 3.0” Downpipe + 3.5” Exhaust = 533 WHP
• 3.5” Downpipe + 3.0” Exhaust = 548 WHP
• 3.5” Downpipe + 3.5” Exhaust = 569 WHP

Takeaway: Larger, uninterrupted exhaust flow unlocks more power, faster spool, and reduced backpressure.
