42 Draft Designs VW Mk5 FSI/TSI Resonator Delete Pipe is designed specifically for the VW Mk5 FSI/TSI '06-'09 models. Instead of the typical through-flowing resonator followed by a chambered muffler, the VW MK5 is equipped with a full-size chambered muffler followed by a thin chambered muffler in the rear. The first muffler does all the work, restricting exhaust flow and trapping all the sound.
The 42 Draft Designs FSI/TSI resonator delete pipe and performance resonator is constructed from CNC mandrel bent 2.5" tubing. Bends are tight, clearing heat shields and suspension without the worry of rubbing or vibration. Press-formed hangers utilize factory hangers - straight and precise. Everything is precision TIG welded. A stainless steel 2.55" sleeve clamp is included to connect the pipe to the factory muffler piping. A reduction is built-in to connect to the factory downpipe piping. Installation requires a simple cut of the factory piping.
Our FSI/TSI resonator pipes are available in two configurations - resonator delete and performance resonator.
A test car was equipped with the 42 Draft Designs street series 3" downpipe, un-resonated. Starting with the resonator delete pipe, the daily driver test vehicle sounded like a race car. A noticeable increase in power was felt throughout the power band. The sound was a bit raw with the 3" downpipe, but free of drone and certainly not too loud. 42 Draft Designs then chopped open the factory muffler to confirm the chambered design. Next, 42DD added our own performance resonator to another prototype and began testing. Surprised and pleased with their results, R&D was completed and production began.
This modification is a true winner. 42 Draft Designs tested the pipes on both our Mk5s with almost every downpipe/catalytic converter/resonator combination and found a range of sounds to suit every enthusiast. 42 Draft Designs documented these sounds in a library of video sound clips. From the start, this modification was designed to be simple without sacrificing quality. Simplicity brings affordability.
Do I need to cut my stock exhaust?
Is this permanent? Yes. A single cut is made in the stock exhaust between the factory resonator and the factory muffler. This cut is simple to measure and can be cut on or off the car. 42 Draft Designs recommends cutting the pipe off the car. This modification is not permanent. One cut is made to the factory exhaust. If you ever need to return the car to stock, simply use the sleeve clamp to re-connect your factory exhaust.
Is there any welding involved?
No. A sleeve clamp is included which allows you to connect our pipe to the factory pipe without welding or leaks.

I installed this on a MK6 TDI with a 3 inch downpipe and an AWE axle back exhaust and it sounds amazing and was just what I was looking for

The pipe came with no instructions. I was still able to install, exhaust sounds and acceleration where a nice and noticeable change.
