The EPA limiting your passion

Nissan RB26 engine with modified turbo and other engine components The Environmental Protection Agency (EPA) wants to demolish your automobile passion and enthusiasm.  Sounds terrible, right?! Alright maybe it’s not that black and white, but let’s see what is really at stake here. With the focus of the Clean Air Act in mind, the EPA wants to make it illegal to modify any manufactured street vehicle’s emission system where its sole purpose is NOT used for racing in organized sports. Ok what is this saying? Basically, modified cars cause an increased amount of air pollution with a tampered emissions system.


Let’s have a clear understanding as to what is at risk here.  Emissions system modifications include any adjustments and or removal of emissions components, in addition to engine management tuning.  Here are a few examples:

  • A catless exhaust system
  • Anything altering air fuel ratios (AFR)
  • Any modifications that allow for more power of your vehicle

Well there’s the first half of it.  Now let’s take a closer look at this statement: “…Clean Air Act to allow the modification of a vehicle’s air emission controls if the vehicle is used solely for competition.”  What exactly does this mean to you, a modified car enthusiast?  It means exactly what it says.   Unless your vehicle ONLY sees use at a race track, it cannot be modified at all!  If the vehicle is found on public roads, it will be deemed ILLEGAL, and the government will have the right to do as they see fit.

So when you’re driving your Nissan 240SX, Subaru WRX, Honda S2000, Dodge SRT8, Corvette Z06 that have any engine or exhaust modifications, you are at risk of having it taken away permanently.  Now this doesn’t stop at you, it affects the aftermarket manufacturing industry as well. Retail shops, tuning facilities and specialists, even automobile events are all at risk.

I’ll leave you with a couple thoughts.

When does impeding on your rights for the sake of protecting the environment seem suitable?  Is there a balance to allowing the automotive enthusiast to continue with their passion while keeping environmental protection in mind?
