help remove higher RPM rapping sound.
my 402 gets really loud whenever I go more than about 25% throttle. Below 25% its just a deep rumble and above that point it the higher pitch exhaust notes get really loud. The 402 in my T/A is exhaling through 1 3/4 stainless long tubes, Jet Hot offroad y-pipe that i hacked up to improve flow at the merge and Magnaflow's stainless 3" cat-back system.
What can I do get rid of the the excess noise? I've thought about adding a muffler in the I pipe like some people do.

1. You can add a bullet muffler to the I-pipe
2. Get a completely different quieter catback
3. Get a catted y-pipe
Note: I personally don't have any first-hand experience with any of these though because I like LOUD.
