42 Draft Design's 1.8T 3" turbo-back exhaust systems combine the 3" downpipes and the 3" cat-backs for a perfect fit from turbo to tailpipe. Thanks to the modular construction of the downpipes, these turbo-back exhaust systems allow the user to switch between street and race series at any time. Repeating the features of the downpipes and cat-backs would only make a long story longer. Though the construction of the downpipes and cat-backs remain the same, we can discuss one feature unique to the 1.8T 3" turbo-back systems - power gains. In 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. *FREE SHIPPING* THE PRICE INCLUDES SHIPPING TO THE 48 CONTINENTIAL UNITED STATES ONLY.
