MadDad Whisper Catback Exhaust for GR STI
A video of my new MadDad 3" Whisper Catback. It is bolted up to an AMR 3" downpipe w/cat. The Exhaust sounds fantastic with no noticeable drone and maintains that Subaru boxer growl. My previous catback setup was a hybrid AMR 3" centre pipe with stock muffler. It sounded very hollow but decent. The problem was that the centre piping was hitting the driveshaft and rear left axle and so it had to go.
I decided to go with the MadDad Whisper because I had one on my '05 STi and loved it. So far, I love this new Exhaust.
First run is a take-off from idle.
First set of drive-bys were done in 3rd gear, moderately accelerating as I passed the camera (~70% throttle), both directions.
Second set of drive-bys were done cruising in 3rd at about 60km/h, both directions.
