Toulbox01 Report post Posted September 1, 2017 Hi Guys, I'm wondering if anyone with an after market exhaust would be keen to share their noise level / decibel readings... and place them to this thread.? I'm sure there's plenty of phone apps that can do this. Typically the reading needs to be 1metre away and on a 45degree angle from the muffler. Info that would help : 1. Exhaust Brand 2. Exhaust set up.. EG: cat back, full system (with or without cats) 3. Noise levels with valves open & closed Quote Share this post Link to post Share on other sites More sharing options...
