The popularity of our prototype 3" turbo-back exhaust systems
certainly took us by surprise. After giving the prototype systems some time to
prove themselves we went back to the drawing board. By far the most popular
request we had was more options! Customers and current prototype owners wanted
the option to swap out the high flow cat on race day. Others wanted the option
to buy a quality 3" downpipe with the same modular design suited to their
current cat-back exhaust. All suggestions were noted and we got to work. The
first step in the re-release of our 3" turbo-backs is our 3" downpipe.
Replacing the factory downpipe and catalytic converter is an
important step when upgrading a 1.8T. The factory downpipe and cat is incredibly
restrictive. Reducing backpressure at the turbo exit increases turbo response,
horsepower and torque. It has been proven that downpipe upgrades provide healthy
power increases on all 1.8T motors. We chose 3" for maximum gains. 2.5"
downpipes are popular and often less expensive, but why not go all out?
Our 3" downpipe begins at the turbo with a CNC machined turbo
flange and a smooth transition to 3" CNC mandrel bent piping. Our downpipe is
bent in one piece to add strength and eliminate unnecessary welds. A stainless
steel flex section is used to absorb engine movement. After the flex section a
CNC machined flange allows a 3" high-flow cat or 3" test pipe to be installed.
We use Magnaflow catalytic converters for all of our downpipes. After the cat, a
custom adaptor allows perfect bolt-on fitment to any aftermarket cat-back. We
offer adaptors for stock sized exhausts, 2.5" and 3". The whole downpipe bolts
together to ensure zero leaks and zero problems. We use triple layer graphite
gaskets and grade 5 locking hardware for the best fit.
The modular nature of our downpipe allows the user to change
configurations at any time. For example, let's profile a typical customer. The
vehicle is a 2005 GTI with stock exhaust. The customer purchases our street
series downpipe with the stock adaptor. The next summer he discovers the local
drag strip and purchases our test pipe to gain some speed on the track. Later,
he decides to install a 2.5" cat-back. By purchasing our 2.5" adaptor the
customer can install the exhaust without additional adaptors, completely
avoiding any unnecessary restrictions. At any time he can reinstall the cat or
stock exhaust by simply swapping out hardware.
Our 3" downpipe is available in 6 configurations. Street
series downpipes include a high-flow cat. Race series downpipes include a 3"
test pipe. Each downpipe includes a cat-back adaptor. Our adaptors are available
in stock size (2.15"), 2.5" and 3". Each downpipe is shipped complete with
everything needed for installation. Additional adaptors, test pipe, cat section,
gaskets, and hardware can be purchased separately at any
