The exhaust note is perfect and surprisingly for a non-resonated system there was no drone in the cabin which was a super +++. Performance wise, the car's response was rapid and extremely smooth. I've already spread the word to my VAG mates
Power gains are very similar to that of the MkV Volkswagen Golf GTi 2.0T FSi. When fitted with the full system and a remap, the exhaust system has shown a massive 25bhp+ gain - on top of the remap!!! We've also received excellent feedback on the sound produced by the new system.
