Question exhaust loudness levels

hey guys so im lookin to find out what exhaust sounds the loudest and which 1 is the quietest. I searched trying different keywords and didn't find any posts relating to exactly what im asking for.I heard greddy tic and blitz are loud, and that the hush is quiet. but i would like to have a list though showing loudest to quietest or other way around. I want to buy a hks hi power exhaust and spraypaint it black to not lure attention from the popo. but i would like to see what are my options. I dont want to spend 700 on a exhaust. 550 is like the most i would want to pay for an exhaust if needed. if there are a combo of video clips that would be awesome. if not just feedback would be really appreciated. from loudess to quietest exhaust. thank you guys for your time and consideration.

Well any fujitsubo exhaust I've heard is fairly quiet. I love mine. It's quiet and doesn't drone on the freeway

my compilation of exhaust clips and videos.

http://www.clubwrx.net/forums/engine...und-clips.html

I haven't updated it in like 2 years though. But people have added their own clips in the most recent posts.



that grid above (not mine) is subjective.

I personally think the loudest catback besides a straight pipe is the Kakimoto.
The quietest exhaust is the jdm Hks Hi Power Silent Version (I have it and it's ridiculously quiet). I've had somebody go WOT 20 feet away from me in my car in a parking lot and I couldn't even hear it that well

To spend $550 and less buy used or have a shop make you an exhaust.

If you need quiet buy used, if you want loud have a shop make you one with a magnaflow muffler.

Also take into account if you plan to run a downpipe (from your 18 posts you must be new to the scene) you could need a different flange at the downpipe/catback connection.

Oh...and keep your stock stuff, you will need it again sometime.
