This system will also fit 99-05 Golf / Jetta 2.0, VR6, and TDI.

This 3" cat-back system begins with a CNC machined flange located roughly 4" into your existing downpipe. Though designed to bolt to 42 Draft Designs 1.8T 3" downpipes, this flanged start allows for a perfect, leak-free installation. After this flange, an oxygen sensor bung allows for installation of the post-cat oxygen sensor. In a straight shot this system bolts to your downpipe and installs at the first hanger, while a resonator removes any rasp from the exhaust note. Next, the system makes the bend around the gas tank and over the rear axle. Fitment in this area is crucial. 42's over-axle pipe is bent correctly and built correctly to avoid rear-axle rubbing on the lowest cars. Next, a Magnaflow muffer is tucked into the heat shields, almost hidden from view. 42's tips not only look amazing, but fit perfectly as well. They are custom made from T304 stainless steel in fully polished, double wall and angle cut form.

Attention to detail shows up in the construction, fitment, and installation of these 3" cat-backs. Flanges are CNC machined in-house from 1018 cold roll steel. Adjustable flanges are used where appropriate to allow each piece to bolt-up as designed on every car. Hanger bars are precisely bent to slide into the factory hangers straight and level. At the rear hanger there are two stainless steel collars designed to lock the position of the rear muffler in place. Once you've adjusted your tip fitment - keep it there! Each and every system is built by hand on production tooling and TIG welded. All the hardware needed for installation is included - gaskets, two lengths of bolts, washers, and locknuts. Mechanical locknuts are included to assure your system never vibrates loose.

The sound of these systems has been imitated since the first clips hit the internet. 42 describes the sound as "quiet when you need to be and loud when you want to be." At idle, the car emits a deep rumble. At low rpms and crusing speeds the sound is mellow and quiet. The exhaust opens up at full throttle and high rpms with a great tone and not a hint of rasp or drone. They tested various resonator and muffler conbinations before finding the perfect balance of power and sound.

While all long-term testing was done on 1.8T vehicles, this system will also fit 2.0, VR6, and even TDI equipped mk4 VWs. Fitment is designed to connect to your existing 3" downpipe. The system will bolt-up perfectly to our 1.8T 3" downpipes, but we also accomodate other brands of 3" downpipes and custom downpipes by including an extra flange. This flange is designed to be welded to the end of your existing 3" downpipe. Precise fitment of our flange to your existing downpipe is necessary in order to fit this cat-back correctly. While this may seem like a hassle, it is necessary for us to assure perfect leak-free fitment. Keep in mind, these 3" cat-backs are designed for factory and custom turbocharged vehicles. Our fitment method is designed to accomodate our 1.8T 3" downpipes and allow custom fitment to any 3" downpipe on any motor.

Naturally, power gains will depend on turbo size, tuning, and what you're replacing. In testing, there were gains of 22.5 HP and 48 lb/ft of torque at the wheels on a stock turbo 1.8T!

Dual tip GTI systems include a pair of 3" tips spaced to fit perfectly within the stock valance. These systems fit all models from 2001+ with the factory dual-tip valance. Height and angle of the cut is designed to reduce drone and not melt the valance.
