Honestly I'm in two minds about this. As stock the car has that smooth, cultured BME I6 noise, which is now gone!
It is loud, obnoxiously loud, and crackles and pops, and BANGS if you lift off near the redline.
Fun, but it's a very different car now. It also farts ands makes a sort of fluffing sound when you pull up to a stop. I fear if it was on a saxo I'd turn my nose up at it!
I want to hear it from behind with someone else driving it so I can hear it for myself, but at the moment I'm still in two minds about it.
The tailpipes are pretty much exactly the same size as OEM, and have a nice polished stainless finish to them, inside and out.
I can't fault the guys at Style Dynamics though, very friendly, welcoming, and kept me informed. I was also asked for my feedback and input at every step of the process.
