It's been an ideal summer for motorcycle lovers and sports car owners, but the warm dry weather has come with a spike in noise complaints.

Police say the main noise culprits are vehicles with tailpipes modified for maximum sound and the majority of complaints come from residents in the West End and downtown core.

"In the summertime, now that everyone is bringing out their bikes and their sports cars, that's when we really see the problem," said Vancouver police acting Insp. Ken Eng.

"I get daily calls from people downtown saying, 'You know what? It's starting up again. Lots of noisy vehicles, It's disturbing our peace.'"

Police have warned owners they could face a $109 fine and three demerit points if their vehicles emit noises louder than 91 decibels.

"If you come into Vancouver with noisy pipes, our officers will be there and you'll likely get a ticket," Eng said.

Police use a subjective method for testing the sound limit. If a noise can be heard from about 200 metres away, it's too loud, Eng said.
