These downpipes are the single most effective performance upgrade available for a Twin Turbo VR 2016+ Q50 or 2017+ Q60. Installing these downpipes will produce an additional 50-60+ RWHP on 3.0t Premium (300 HP) models and 25-35+ RWHP on Red Sport (400 HP) models with no additional modifications and no tune required, although a catback exhaust system is recommended to reach full potential. The factory exhaust utilizes 4 catalytic converters mounted directly off of the turbo outlets. These cats are by far the largest restriction in the VR30DDTT’s respiratory system, slowing down exhaust flow and creating substantial backpressure. Our catless expansion downpipes allow the turbos to breathe and spool up substantially faster resulting in a dramatic increase in horsepower and torque across the entire powerband. The expansion design allows hot gasses exiting the turbo to smoothly expand out into full 3.0″ 304 SS piping, the resulting pressure differential on the back side of the turbine wheel results in insanely fast spool and increased maximum boost pressures. As the exhaust gases cool further downstream they are funneled back down into a 2.5″ outlet compatible with factory and most aftermarket catback exhaust systems. Z1 can also provide these downpipes with a full 3.0″ outlet flange via the options below.
Our downpipes utilize factory style V-band flanges to fit the stock turbos with no aftermarket hardware needed. (Use of the existing OEM V-Band Clamp is required.) The fitment of these downpipes cater to factory design of the catalytic converters and y-pipe, allowing you to bolt these in place of the factory converters with no modification necessary, utilizing all factory mounting points for great fitment on factory and aftermarket exhausts. These downpipes can be installed without removing the engine in a few hours using the proper tools. Removing the stock catalytic converters with the engine in the car is tricky but entirely possible as we have done it several times using the proper extensions and swivel sockets. In addition, downstream oxygen sensors mount in J-pipe O2 bungs to reduce the likeliness of check engine lights after installation. We have not experienced any CELs or diagnostic trouble codes on our Q60 and Q50 equipped with these downpipes for several thousand miles of testing, but we cannot guarantee they won’t appear until software is released to account for this upgrade.
