In Quebec anything non-oem is considered ILLEGAL!
Modified car exhaust systems lighten drivers' wallets
$1,200 alteration costs Civic owners $138 fine

A Gatineau judge has fined 12 car owners, mostly the drivers of Honda Civics, for using performance exhaust systems that create too much noise.

Justice Georges Benoit ruled that Surete du Quebec officers could use their own judgment and a ruler to determine whether car owners are using non-standard mufflers. Each driver had to pay a $100 ticket plus $38 in costs.

Sgt. Marc Ippersiel said yesterday police stopped the drivers last summer on Highways 5 and 50, after they noticed what appeared to be high-performance exhaust systems. He said officers used a 76-centimetre ruler to determine whether the mufflers contained baffles.
If the entire ruler could be inserted into the pipe, police issued a ticket because the car had a modified exhaust system.

Sgt. Ippersiel said the drivers argued in court that police couldn't determine the decibel level of the exhaust systems without special equipment. The judge ruled that all the police had to do was prove that the cars were equipped with modified exhaust systems.
"You can't enter a normal muffler with a straight stick," Sgt. Ippersiel said. "If the stick passes through the pipe, it proves the car has a straight exhaust.

"Mostly it is Honda Civics that are modified by owners. It is like a fashion trend. When drivers buy this equipment at speed shops, they aren't told it is illegal."

Lee Burke of Ottawa, who drives a 1994 Civic equipped with a $1,200, "52-state legal" performance exhaust system, has been ticketed twice by police in Ontario and Quebec. "I was driving down Highway 5 near Chelsea when the police stopped me," Mr. Burke said. "I don't think this is fair because big trucks, Harley-Davidson motorcycles and OC Transpo buses produce more noise.

"This is a campaign against performance cars and any kind of street racing. But I use the car for drag racing at tracks, not on the street."
Ontario Provincial Police Const. Eric Booth said drivers can be fined $110 in Ontario for causing unnecessary noise by using a performance muffler, playing the car stereo too loudly or squealing the tires.

"Loud mufflers are an ongoing problem in built-up areas," Const. Booth said. "These are modified street cars -- mostly imports the drivers say are not for racing. The drivers have a little more pride in their cars and will put money into modifying them."
