Bolt-On Horsepower and Torque
42 Draft Designs 3” downpipe is the single most effective bolt-on upgrade for the Volkswagen Tiguan. No other basic physical modification can compete with the power gains delivered by this fundamental upgrade. Simply by reducing backpressure we’re able to create usable horsepower and torque throughout the power band while also improving turbo spool and throttle response.
Fabricated here in the USA, our exclusive downpipe for the TSI engine installs without permanent modification. Precise pipe routing and a stainless steel flex section assure hassle-free fitment. Downpipes are equipped with a 400/cell high-flow catalytic converter. Included adapter reduces pipe size to utilize the OEM band clamp.
To configure this downpipe to meet your specific needs please browse the available options above.
This downpipe is known to fit the following vehicles:
- Professional installation is highly recommended.
- 2009-2011 Tiguan 4Motion (Tiguan 1 / Mk1)
- Included adaptor allows fitment to stock exhaust
- Will fit any cat-back exhaust that reduces to stock diameter
*Model years listed are based on US models. European model years may differ. If shopping for a vehicle sold outside the US please match chassis designation before matching model year.
Every 42 Draft Designs exhaust system is scratch-built from straight tube and flat steel. Our team of professional metal fabricators cut, bend and form raw materials with precision. Piping is mandrel bent in-house using our Baleigh CNC mandrel bender. Flanges and brackets to fit each system are cut on our OMAX waterjet. Additional forming takes place using our Huth end forming equipment and our Dake 100 ton press. We use ONLY the finest North American made materials proven to stand the test of time.

Every component of each individual exhaust system is treated to a precision assembly and test fixture. These fixtures allow our fabrication staff to accurately build, weld, and test each assembly. Nothing's worse than a product that doesn't fit; so we work smart to ensure every system fits like the first.
After assembly each exhaust system is TIG welded by our team of professional welders. Our welders take their time, preparing, welding and inspecting each joint with care. From raw material to final welding we never rush, cut corners, or take shortcuts.
Due to the exacting nature of our fabrication process it's normal for your exhaust system to require a few days of fabrication before shipping. Many of our systems are in stock; however it would be impossible for us to stock our entire exhaust system lineup. In the past 10 years we've found that our customers are more than willing to wait a few extra days - especially for a complete system that's built to last.
Throughout our exhaust systems we use the highest quality American made materials. Our piping is shipped directly from the mill, wrapped in a crate to prevent dents and scratches. We use heavy gauge aluminized steel and stainless steel tubing designed specifically for mandrel bending. Flanges, brackets and hangers are cut from cold roll steel. (Hot roll steel is more economical, but we're willing to pay more for clean, flat steel free of scale and glaze.)
In the end, our attention to detail and demanding material choices increase the retail price of our exhaust systems. When compared side-by-side with the competition our products always stand out. We use better materials that are proven to stand the test of time. We put more time and more care into each of our exhaust systems than anyone in the business. Quality, performance, fitment accuracy, and your satisfaction are standard features of all 42 Draft Designs exhaust systems.
EXHAUST OPTIONS EXPLAINED
STAINLESS STEEL
Our stainless steel systems are straight-forward. We build your system using 304 stainless wherever possible. Starting with the flanges, we use 3/8" thick 304 stainless steel for every flange. Flanges are cut with precision on our OMAX Waterjet. Piping is mandrel bent per system using our CNC Mandrel Bender. We use the highest quality 304 stainless tubing designed for mandrel bending. Mild steel components such as 02 bungs and hangers are replaced with 304 stainless steel equivalents. We even replace the hardware with stainless steel bolts & copper locking nuts. Nothing is left to chance.
V-BAND FLANGES
42 Draft Designs now offers v-band connection flanges with our stainless steel exhaust systems. Compared to 3-bolt flanges, exhaust systems built with v-band flanges are easier to install and adjust. V-band connections don't require a gasket, and can be serviced with a single tool. Overall, v-band flanges speed-up initial install and repair work.
Our v-band flanges are CNC machined in-house from 304 stainless steel. We've created a male/female fitment specification for our flanges which aids in sealing the connection. We use Clampco stainless steel v-band clamps. Due to the material cost and manufacturing time, v-bands will remain a premium option.
BEWARE OF SHINY JUNK
We are well aware that the internet is full of shiny stainless steel exhaust systems sold for unbelievable prices. These "stainless steel" systems are hardly exhaust systems. They are barely stainless steel and almost always a poor copy of an US or European system. The material used to make these systems is not certified or regulated. It's mostly US scrap metal shipped back on empty cargo ships. There's no telling what "grade" this material is. It's much thinner than advertised and typically breaks at the hot spot. What they claim are stainless steel flanges are really just thin, plasma cut hot roll steel flanges dipped in a chrome bath. Most of the time their "TIG" welds are just sloppy dress-up passes over MIG welds that are way too hot. There's more to tell, but I think we've made our point.
42 Draft Designs uses ONLY the finest North American made 304 stainless steel. We're not messing around. Our material is certified grade 304 stainless steel. We maintain our 16 gauge pipe thickness and 3/8" flange thickness when building our stainless steel systems. Every joint is meticulously TIG welded. Nothing is ground, sanded, brushed, polished, coated or otherwise covered up.
In the end, our attention to detail and demanding material choices are reflected in the value of this upgrade. When compared side-by-side with the competition our stainless steel fabrication always stand out. We use better materials that are proven to stand the test of time. We put more time and more care into each of our stainless steel exhaust systems than anyone in the business. We don't hide sloppy work by polishing our systems.
42 Draft Designs products are manufactured from scratch in Millersville, MD. We use high-quality American-made materials throughout our products, manufacturing in-house every component possible. When necessary to outsource, we start with American companies that manufacture their products in the USA. Our modest manufacturing facility is staffed by a team of 12 machinists, metal fabricators, and TIG welders trained to work in exacting precision. From design to manufacturing we never rush, cut corners, or take shortcuts.
Due to growing demand for our products, lead times may exist.
Most items with a lead time are considered 'Made To Order' items and are subject to an early cancelation fee and a restocking fee if returned.
