Hello! I tested my new sports exhaust today, is a FOX system, from KAT. Acceleration in different gears, on a road with a slight incline. 40 – 120 in the 3rd gear returned 25s series, 24.5s with sports exhaust 40 – 120 in the 4th gear returned 34.5s series, 35s with sports exhaust 60 – 120 in the 5th gear returned 37.25s series, 36s with sports exhaust So, much noise about nothing. Seriously, the thing is so loud. Does anyone have experience how to protect the interior from the noise? My idea would be, Glue insulation mats between heat shields and wagon floor.
