Take a video from outside the car and rev it a bit.
Yeah I know that's why I said it's hard to tell exhaust note from videos. There definitely is more low frequency/burble coming through but it's hard to hear when you record on an iphone and play on a PC.
It's not a loud exhaust - but definitely a bit more than stock.

You can, however, get your car tuned to use those mods properly and gain a proper improvement. I tuned my own 2.5i and got a 10% improvement in power and torque without changing anything else. The car is much more fun and extra-driveable now.
Plan is to get it tuned as soon as the tuners have figured out how to get into the Hitachi ECU
