The drone was too much for me, you could hear everything vibrating and rattling after a period of time, imo its not worth it, just take off 2 only.

Alternative option is to get a valve installed, which allows you to run the stock exhaust system, but at the flip of a switch, open the pipes and have the full noise.

You can place the valve at different points in the exhaust system depending on how much volume you want. You can bypass the rear 2 mufflers, or bypass all of the silencing entirely by putting it after the cats.

I second this, ran a diverter valve for a few months on my ls400 right before the 4 mufflers. If you do this though, I strongly recommend you get a very high quality one (at least $100-$150). The one I got was from a no-name seller on eBay, and the butterfly valve kept leaking and rattling. Not a fun experience.

Can't agree with this more. Spend good money on a high quality valve. An exhaust leak after 6 months is the last thing you want to have to go back and address at additional labor\time\headache\expense.
