If serious power gains and exquisite sound is what you're looking for; consider the search officially over. Our 1.8T turbo-back exhaust systems provide instant results: significant horsepower and torque gains, high performance sound, and worry-free fitment. More than just a pile of pipes, our turbo-back systems are precision fabricated from CNC machined flanges, CNC mandrel bent piping, Magnaflow mufflers, and mirror polished tips. The result of our meticulous metalworking is a heavy duty exhaust system that fits like it should and outperforms the competition.

Modular by design, our turbo-back systems are available in street or race configurations. Street series systems include a Magnaflow 200 cell catalytic converter. Race series systems include a test pipe. On race day the cat can be easily swapped for a test pipe. Six unique tip fitments allow our turbo-backs to fit any mk4 1.8T.

Our 1.8T turbo-backs are technically a combination of our 3" downpipes and our 2.5" & 3" cat-backs. Repeating the features of our downpipes and cat-backs would only make a long story longer. To learn more, follow the links below to review the detailed construction and fitment information for both systems.

One feature our downpipes and cat-backs can't boast on their own is power gain. In our extensive testing we were able to dyno test a 'typical' mk4 and measure the changes. We used a relatively stock 2002 GTI 337 edition. The car was chipped, had a cold air intake and an aftermarket diverter valve. No other engine modifications were made to the car. Equipped with stock exhaust, we drove the car thoroughly and dyno tested it. The stock exhaust was swapped out for our 3" turbo-back system and the car was driven to adapt then dyno tested again. With weather conditions literally exact we measured peak gains of 22.5 hp and 48 lb/ft to the wheels! Power gains were felt all over. Boost was built faster and held out longer with the stock turbocharger. No power losses were felt at any point in the powerband.

Turbo-back pricing starts at $770 and varies by series, pipe size and tip fitment. All configurations can be purchased ceramic coated.

Tip Fitments

Tip fitments are semi-permanent in our exhaust systems. In order to change the tip later down the road you will need to swap out the rear muffler section. Please contact us directly for pricing in the event of a tip change. Please try to ignore anyone who says "just take it to a muffler shop and have them weld on a new one." It's not that simple. The muffler and hanger is in the same location on all systems, but the tip itself and the pipe in-between differ greatly. Simply cutting one tip off and welding on a different one won't result in a system that meets our quality standards. Contact us.

Our tip fitments are very specific. Here are a few specific tip scenarios we would like to mention:

• Our dual tips will not fit under a non-cutout valance
• Our single tips will not fit under a dual tip cutout valance
• Our hidden tip is hidden, unless installed behind a cutout valance
• GTI systems will not fit Jettas
• Jetta systems will not fit GTIs

Non-Resonated System

We do not offer our turbo-backs in a non-resonated configuration. Again, there's a specific reason. Long term testing proved to us that a non-resonated 3" system with our rear muffler is not a product we would like to put our name on. It doesn't sound great. It sounds raw and perhaps a bit 'import.' Our resonator does not affect the flow of the exhaust system in any way. It cleans up the sound of the 1.8T and plays a major part in the high quality sound of our exhaust. For this reason, we do not offer a non-resonated configuration.

Motor Mounts Recommended

We highly recommend upgrading your dogbone motor mounts when using our turbo-back exhaust system. Worn out factory bushings cause excessive engine movement. Engine movement translates directly into the exhaust system - flex section or not. If your engine is slinging back and forth so is your exhaust. This means rattles, panic, and worry. Our system is designed to be used with motor mounts. The fitment is exact - 3" piping is alot to stuff under a car designed for 2" piping.
