The TIG-welded 304 stainless and investment cast body delivers addictive sound, quality finish, effortless install, reliability, and maximized performance for your turbocharged V6.
*Requires Stage 2 or hybrid turbo ECU tuning
MOTORSPORT SOUND
IE's unique thick-wall investment castings produce an aggressive, drone-free exhaust note without the "tinny" sound typical on most full stainless body aftermarket options. Enjoy not only a louder exhaust but one with improved engine and turbo notes that will deliver miles of smiles.
INVESTMENT CASTING
Other aftermarket downpipes use large sections of thin-wall steel tubing to manufacture the downpipe body; this is a cheaper process but can reduce sound quality and sacrifice exhaust flow. Investment casting allows for an optimized design that smoothly transitions exhaust flow from the massive 6" body to the dual 2.5" exhaust legs. The casting also provides a beautiful look that turns the entire downpipe into an attractive gold finish as it wears in from heat cycles over time.
PERFECT FIT
The B9 3.0T hot-v style engine has a unique center-mounted turbo with a large downpipe that quickly splits into twin-sided exhaust sections. This challenging configuration requires exacting alignment to avoid install hassles, rattling, rubbing, and exhaust leaks. IE engineers utilize advanced 3D scanning technology and rapid prototyping to guarantee a flow-maximized design that exceeds even the factory fitment.
200 CPSI CATALYTIC CONVERTER
IE's downpipe includes a high-flow 200 CPSI catalytic converter. This performance CAT allows for full and unrestricted power from Stage 2 ECU tunes and hybrid turbo upgrades while reducing emissions output and eliminating unwanted smells and bumper stains found on cat-less designs.
Catalytic converter warranty is only available for cusotmers running IE performance ECU software.
HYBRID TURBO READY
The stock downpipe becomes a significant restriction when upgrading to a larger hybrid turbo. IE's cast downpipe is a direct-fit to available upgraded turbochargers on the market and will allow total horsepower, torque, and spool potential from your turbocharger investment.
IE's B9/B9.5 S4 & S5 intake system, turbo inlet pipe, and downpipe are hybrid optimized, making the installation of popular turbo upgrades an easy bolt-in process.
