VW Performance Parts: 42 Draft Designs 2.5" Slip Fit Cat-Back Exhaust System for Jetta (EX-04-1J2SS)

42 Draft Designs Mk4 Slip Fit Cat-back Exhaust Systems are designed specifically for VW Mk4 Jetta '99-'05 2.0, 1.8T, 12v VR6, 24v VR6, and TDI models. Our 42 Draft Designs new 2.5" slip fit cat-back is a "back to the basics" system designed for everyone. True slip-on and bolt-up installation requires few tools and no modification. The sound of this slip fit cat-back exhaust is race-inspired and refined. Best of all, a healthy power increase can be instantly felt.

The 42DD 2.5" slip fit cat-back system begins where the factory catalytic converter ends. A reduction to 2.15" piping allows 2.5" piping to slide into the factory sleeve clamp. After the clamp, an accurately positioned pair of hangers provide support for the entire system. Next in line, a Magnaflow resonator removes rasp and drone from the exhaust note. An adjustable flange connection follows, allowing precise adjustment of 42DD piping as it travels around the gas tank and over the rear axle. Fitment in this area is crucial. The 42 Draft Designs over-axle pipe is bent correctly and built correctly to avoid rear axle rubbing on the lowest cars. Another adjustable flange completes over over-axle pipe, allowing even further adjustment. Next, a Magnaflow muffler is tucked into the heat shields, almost hidden from view. Your choice of hidden, single, or dual exhaust tips complete the system.

Exhaust tips can make or break a system. So, 42DD builds their tips in-house and polishes them to a mirror finish. The 42 Draft Designs 2.5" slip fit cat-back is available with the choice of three tips. Hidden tip systems offer a basic downturn tip, hidden from view. Single tip systems position a highly polished 4" tip neatly in the factory cutout. Dual tip systems pair two highly polished 3" tips and hang them accurately under the rear valance. All stainless steel tips are available in single wall and double wall construction to suit the style of every enthusiast.

Additional Details

Installation is simple and reliable. A permanent reduction allows use of the stock sleeve clamp. Precise design and fabrication routes 2.5" piping clear of heatshields and suspension components. Adjustable flanges allow adjustment at every connection, sealed by double layer graphite gaskets and locking hardware. A pair of locking collars sandwich the rear hanger bushing, locking your final adjustment. This 42DD system can be installed on 2.0, 1.8T, 12v & 24v VR6, and TDI equipped Mk4s.

The sound is sporty and refined - not too loud and not a hint of rasp. Compared to stock, the car emits a noticeable rumble at idle. At low rpms and cruising speeds the sound is mellow and defined. The exhaust opens up at full throttle and high rpms with a great tone and not a hint of rasp or drone. Sound varies by motor, though never poorly. We tested various resonator and muffler combinations on each motor before finding the perfect balance.

Horsepower and torque gains are strong and immediate, adding power throughout the powerband. for these cat-back systems cannot be universally stated. These 42DD cat-backs can be installed on a wide range of vehicles - from a bone stock 2.0 to a supercharged VR6, to a K04 1.8T. Power gains are always strong and smooth. Peak gains depend on your motor type and supporting modifications.

Tip Fitments

42 Draft Designs 2.5" slip fit cat-back is available with the choice of three tips, all with unique fitments for Jetta and GTI models. Fitment of each tip is specific to the rear valance on the vehicle and cannot be interchanged. Some tips are available in different styles. Fitments and styles are explained in detail below.

  • Hidden tip systems offer a basic downturn tip, hidden from view. Exhaust gases are dumped before the start of the rear valance. Height and angle of the tip is designed to reduce drone and not melt the valance. The tip is exposed only 1/2" below the bottom of the valance. Hidden tips are aluminized steel and are not polished.
  • GTI single tip systems feature a 4" tip designed to fit the 337/20th Anniversary Edition rear valance.
  • Jetta single tip systems feature a 4" tip designed to fit the GLI single tip valance.
  • GTI dual tip systems feature two 3" tips paired and positioned to fit within the factory cutout.
  • Jetta dual tip systems feature two 3" tips paired and positioned to fit within the factory cutout.

Single tips and dual tips are available in two styles - single wall and double wall. Single wall tips are constructed from a single 3" tube. Each tip is angle cut and welded to a press-formed expansion. Double wall tips are constructed from two tubes - an inner barrel and an outer barrel. The inner barrel is angle cut and press-formed to precisely meet the angle cut 3" outer barrel. Both tip styles are highly polished inside and polished to a mirror finish outside. Tip options are offered to suit the style of every enthusiast.

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 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 42 Draft Designs quality standards.

42 Draft Designs tip fitments are very specific. Here are a few specific tip scenarios worth mentioning:

  • 42DD dual tips will not fit under a non-cutout valance
  • 42DD single tips will not fit under a dual tip cutout valance
  • 42DD 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

42 Draft Designs 2.5" Slip Fit Cat-Back Exhaust System is not offered in a non-resonated configuration. Long term testing proved that a non-resonated 2.5" system is not a worthwhile product. It doesn't sound great. It sounds raw and perhaps a bit 'import.' The 42 Draft Designs resonator does not affect the flow of the exhaust system in any way. It cleans up the sound of the motor and plays a major part in the high quality sound of the exhaust. For this reason, a non-resonated configuration is not offered.

Motor Mounts Recommended

It is recommended to upgrade your dogbone motor mounts when using our cat-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. The 42 Draft Designs 2.5" Slip Fit Cat-Back Exhaust System is designed to be used on lowered cars with motor mounts.

    This cat back exhaust system is made with quality craftsmanship in mind. Fitment is perfect and sounds great. I would recommend this system to any MK4 vr6 enthusiasts who desire performance without breaking the bank on other exhaust upgrades.
