High Performance Sound & Flow - Affordable!
When modifying Volkswagens, deleting the factory resonator has always been considered a "cheap" modification yielding equally "cheap" results. The Mk5 exhaust is different. The first day we lifted our Mk5 we noticed VW's muffler choice. Instead of the typical through-flowing resonator followed by a chambered muffler, the MK5 is equipped with a full-size chambered muffler followed by a thin chambered muffler in the rear. It was clear the first muffler did all the work, restricting exhaust flow and trapping all the sound. We had to try it, so we built some ugly prototypes and started testing. Here's what we found:
Our test car for this project is equipped with our street series 3" downpipe, un-resonated. We started with the resonator delete pipe. Instantly this daily driver 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. We chopped open the factory muffler to confirm the chambered design then added our own performance resonator to another prototype and began testing. The sound cleaned up and quieted down. Surprised and pleased with our results, R&D was completed and production began.
This modification is a true winner. We 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. We've 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.

Before ordering please read over our FAQ and listen to our sound clips to decide which pipe is right for you. If you have any questions, feel free to contact us at any time.
Our 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, detailed in our installation instructions and pictured below.
Our FSI/TSI resonator pipes are available in two configurations - resonator delete and performance resonator. Sounds clips and additional information are available below to help you decide which pipe to choose.
