You guys are actually wrong about the size of the exhaust issue.
The size of the exhaust isn't what they look at, it's really the "volume" is what they go by. You can get excessive noise tickets if a cop deems the exhaust to be too loud.
A buddy of mine and member of this forum got a ticket for just that. He either had an exhaust leak or he was getting his exhaust done and was driving sans muffler and the cop gave him a ticky ticky
yea size does not matter. if thats the case the stock exhaust on a powerstroke diesel would be like illegal lol... i swear some of those diesel trucks with aftermarkter 5 inch exhausts have like 20 inch tips lol
Great...but we're not talking about airflow. We are talking about what the MVA says in relation to the
size of your exhaust, and how they interpret it when looking at your exhaust.
Where is says "may not be "opened or widened" they are talking about size, airflow is secondary to this.
I guess I should have been more clear.
When they read the opened or widened part, they
could interpret that as someone taking pliers to their exhaust and opening/widening it...rendering it illegal.
OR
If you have an aftermarket one, they
could say "Well you have a bigger exhaust on there, and therefore...you must have more airflow. Let's take a closer look and see if it's legal." (that's what happened to me.)
Here's my proof for all the haterade drinkers:
Vehicle noise
27 A motor vehicle shall be equipped with an exhaust muffler which complies with section 7.03 of the regulations.
The opinion of an inspector as to whether the engine and exhaust noise is greater than that made by other vehicles in good condition of comparable size, horsepower, piston displacement or compression ratio shall determine whether exhaust gases are expelled with excessive noise.
When tested in an inspection station, the vehicle engine, any auxiliary engine and exhaust level shall not exceed Table 3 standards.

More stuff from the MVAR. Note it says NO widening of exhaust outlet!!
