Mario Posted November 20, 2012 Share Posted November 20, 2012 Good point. Here's a thread typical supra exhaust notes, maybe of any use for comparison which i think will be very difficult. http://www.mkivsupra.net/vbb/showthread.php?193462-Video-of-your-SUPRA-exhausts-!&highlight=exhaust+sounds Anyhow, 94 db is nice, if you want to make more noise 4inch will be your outcome;) Link to comment Share on other sites More sharing options...
neilp9876 Posted November 20, 2012 Share Posted November 20, 2012 The hi power silent on mine when decatted was around 103DB, they're not very silent. Link to comment Share on other sites More sharing options...
Noz Posted November 20, 2012 Share Posted November 20, 2012 Whats the legal limit? I'm concerned my new setup will be too loud. Link to comment Share on other sites More sharing options...
neilp9876 Posted November 21, 2012 Share Posted November 21, 2012 Is there a legal limit on the road? I know that some Ferrari's are way over 100 out of the factory. I only changed mine to get within track restrictions. Link to comment Share on other sites More sharing options...
Dan_Turism0 Posted November 21, 2012 Share Posted November 21, 2012 there is no 'legal limit' however you can be reported for excessive noise, general rule is don't go nailing it through a housing estate late at night or through town centres drawing attention to yourself and you'll be fine Link to comment Share on other sites More sharing options...
Steve Paine Posted November 21, 2012 Share Posted November 21, 2012 My car has an HKS Silent power and my ears still feel like I've been at a concert after a 3 hour drive. Still tinnitus rules!
