42 Draft Designs VW Mk4 1.8T 3" Value line Downpipes for VW & Audi take a clear-cut approach and are built on the same precision tooling as the 42 Draft Designs Mk4 1.8T 3" Downpipes. 42 Draft Designs eliminated their modular flange design to create a downpipe that embodies simplicity. Welded permanently with only a pair of options, these downpipes deliver equal results at a dramatically lower price. Why build the same downpipe with less features? Some enthusiasts simply don't need modular options. Years of market feedback has shown that the modular design is ideal, however confusing for those seeking simplicity. Determined to eliminate confusion, 42DD scrubbed the sales data and built a downpipe based on the most popular fitment configurations. Value line downpipes are available in street and race configurations with a choice of three pipe size adaptors.
Like any 42DD exhaust system, Value Line systems are fabricated with precision and TIG welded to ensure maximum quality. Each Value Line downpipe starts with a CNC machined turbo flange and press-formed transition. Mandrel bent piping routes exhaust under the car where a stainless steel flex section is used to absorb engine movement. After the flex section, piping connects to a final reducer. This reducer allows fitment to any cat-back exhaust - stock or aftermarket. Street series feature a high-flow cat, permanently welded in-place. Both series feature a pair of oxygen sensor bungs positioned for honest fitment.
At any price point, a downpipe is a worthwhile upgrade for the 1.8T engine. Since the 1.8T first hit the streets, performance shops and enthusiasts have proven that downpipe upgrades provide healthy power gains. Equipped with a very restrictive factory downpipe and catalytic converter, the 1.8T instantly benefits from a reduction in backpressure. 42 Draft Designs downpipes increase turbo response, horsepower, and torque.
Value Line Mk4 1.8T downpipes are available in street or race series. Street Series downpipes are equipped with a 200/cell high-flow catalytic converter. Race Series downpipes are straight-through for track day. Included adaptor reduces pipe size to utilize the OEM band clamp. Additional cat-back adaptor sizes are available.
