Best Bolt On Combo For Minimum Drone/Rasp/Hiss
 

Looking for a combo that has the least amount of drone/rasp/hiss, but able to put down good HP numbers. Post your bolt on combo, HP numbers, and how close it matches my description. Also point out if you are tuned or untuned.

Thanks!

Honestly the quietest way to go is do a true dual to your stock muffler. You will get some gains and increase gas mileage but you won't like the way it sounds at wot. I just recently added top speed axle backs and sounds way much better but there is a bit of drone to deal with. It's either going to be quiet or a bit loud no matter what route you go. I will be installing hush mat in my doors and hatch area to get it quieter inside the car. Good luck finding that perfect exhaust.
