Is the Utah legislature moving to ban all aftermarket exhausts?

According the SEMA Action Network, a bill has been introduced in Utah that will "ban the use of aftermarket exhaust systems." The organization is urging people to contact Utah Senators immediately to protest the substitute bill (S.B. 106), introduced by Senator Patricia Jones, for the following reasons:

• S.B. 106 ignores the fact that aftermarket exhaust systems are designed to make vehicles run more efficiently without increasing emissions.
• S.B. 106 does not supply law enforcement with a clear standard to enforce, allowing them to make subjective judgments on whether or not a modified exhaust system is in violation.
• S.B. 106 fails to recognize that aftermarket exhaust systems offer increased performance, which can make a vehicle safer by improving its ability to merge, pass, travel uphill, etc.
• S.B. 106 would make it difficult for hobbyists to replace factory exhaust systems with more durable, better performing options.

We took a closer look at the four-page bill, and didn't find anything overly alarming to our enthusiast-tuned eyes. Aside from the typical bureaucratic jargon, we read the bill as providing definitions about excessive noise standards and a clarification about aftermarket devices. Furthermore, the bill specifically says "...an air pollution control device may be substituted for the manufacturer's original device if the substituted device is at least as effective in the reduction of emissions from the vehicle motor as the air pollution control device furnished by the manufacturer..." So we're failing to see the issue? Posit your own theories and thoughts in the comments below.
