i don't have an exhaust yet but the best thing to do is change the tip, that should help. my 03 Tiburon with the cat-back exhaust is annoying especially between 2k and 3k rpms. when i first got it the first few days my ears were ringing when i got out of the car. i could prob deal with the drone you have, i personally think the v8 drone with a good muffler is better then 2 fart cans:jester: but i know where your coming from.
I just had a Magnaflow muffler put on today along with a chrome tip coming out the passenger side. I can see where it might drone but so far on my trip home on the highway at 70mph I barely even noticed. Just a nice deep rumble.
