Invidia 08-14 WRX/STi 5 Door 80mm Single Outlet Full Titanium Cat-Back Exhaust
The Invidia Single Outlet Full Titanium Exhaust is a purpose-built system for enthusiasts chasing every last bit of performance. Designed for weight reduction, maximum flow, and an aggressive tone, this system strips away unnecessary bulk and channels exhaust through a single, high-flow outlet — all while being constructed entirely from ultralight, aerospace-grade titanium.
Every component of this exhaust is made from high-purity titanium, yielding a system that is typically 10–15 lbs lighter than its stainless-steel equivalent. That weight savings translates directly into quicker throttle response, improved transient behavior, and better overall handling. The titanium material also gives the exhaust its signature blue-purple hues around welds and tips — a visual cue that screams performance pedigree.
In terms of acoustics, the single outlet layout offers a more raw, motorsport-inspired sound profile compared to dual systems. The straight-through design minimizes restrictions and produces a sharp, high-pitched tone that’s distinctly titanium — crisp at idle, raspy under load, and spine-tingling at redline. While this system leans toward the louder side, it avoids excessive drone, especially when paired with a catted downpipe or resonated front pipe.
Ideal for those seeking the most direct expression of power, the Invidia Single Outlet Titanium system excels in both function and form. Whether you’re shaving lap times or turning heads, it delivers on all fronts.
