I did AA xpipe and HFC and it is huge difference. In noise level and the car is much more a beast.
Downside is alot more energy/noise from under the car and overall the car will exhibit more small rattles and buzzes due to the more open exhaust and just an increase in resonance of the exhaust system. It is so open now. There is a balance and the Xpipe and HFC is really at the edge of having a luxury fast car, much more edgey for sure. |
