Do exhausts get louder over time?
I have a Herrod Motorsport 2 1/4" stainless catback on my LR Focus. It is about 2 years old. It is still quiet when running along, but when I put the power down, the exhaust note seems much louder. Is that normal (buildup in the exhaust?) or is something deteriorating??
