I've got a fair bit of in cabin drone coming from this exhaust. It's pretty loud from inside the cabin, you can drive it in a way that you don't get much drone... something I will perhaps get used to. But the gains made are great. I suppose gains come at the cost of noise.
Well the genius of it is in the muffler as I'm sure your aware

upto 5000rpm it's the same as stock when you drive normally(roof up), even with the roof up in VTEC on the track the engine sound still overpowers the exhaust in car, roof down it's all exhaust, it really opens up (sound wise) when you get into VTEC...

For example, on a track like winton or calder, the you can't hear the exhaust when the car goes past you on the straight, unlike most other aftermarket exhausts!
