PROFILE

Take your MK3 Audi TT to the next level of tuning with the all-new ARM MK3 Audi TT Downpipe.  Upgrading the downpipe on your MK3 Audi TT is essential if you're looking to get the most power out of your Gen 3 E888 engine.  The OEM Audi TT downpipe is restrictive,  preventing you from running any more than a basic Stage 1 tune safely.  The ARM MK3 Audi TT Downpipe relieves your turbo of excessive backpressure, allowing you to increase the boost by flashing to Stage 2 maps and beyond.  The result is faster turbo spool, increased power and torque, and an improved exhaust note. 

CONSTRUCTION

Constructed of TIG welded T304 grade stainless steel, the ARM MK3 Audi TT Downpipe is designed to fit perfectly, and last the lifetime of your TT.  The ARM MK3 Audi TT Downpipe is comprised of 3 sections: an upper section, midpipe section, and adapter.  Each section of the ARM MK3 Audi TT Downpipe is joined by precision machined v-band connections.  These v-band connections allow for a secure and leak-free joint between all sections of the ARM MK3 Audi TT Downpipe.

The laser-cut mounting bracket and CNC machined mounting prongs make for a precise fitment to your stock downpipe mounting points.  

The ARM MK3 Audi TT Downpipe kit comes with a reducer to connect to any exhaust system that fits the stock slip joint.    It also comes with a straight 3" section to connect to catback systems that support a 3" transition between the downpipe and catback section. 

The ARM MK3 Audi TT Downpipe incorporates a stainless steel flex section between the turbo and mid-pipe mounting point.  The addition of this flex section reduces tension on turbocharger caused from torsion during hard acceleration, cornering, and braking.
