California regulates automobile aftermarket parts that have the potential to impact emissions. In most cases, the sale and use of emissions related aftermarket parts on automobiles is prohibited unless it is either a “replacement part” as defined by California, or is a specifically authorized use of that part as reflected in an Executive Order (“EO Part.”)

The California Air Resources Board (ARB) regulates aftermarket parts and has promulgated regulations that essentially place all emissions related aftermarket parts into three categories:

(1) Replacement Parts Replacement Parts are aftermarket parts that ARB considers to be functionally equivalent to the stock part they are intended to replace, and therefore would not impact the emissions from these vehicles. These parts are appropriate for sale and use on automobiles used on or off the public highways. For aftermarket exhaust systems and parts, there are two applicable scenarios:

(a) If the automobiles stock exhaust system does not contain a catalytic converter, then an aftermarket exhaust part is a replacement part as long as the part does not remove or replace any emission control equipment originally attached to the stock exhaust system, such as oxygen sensors.

(b) If the automobiles stock exhaust system contains a catalytic converter in the manifold section of the stock exhaust system, then an aftermarket muffler positioned downstream from the catalytic converter (i.e. cat-back) is a replacement part as long as the part does not remove or replace any emission control equipment originally attached to the stock exhaust system.

(2) Executive Order Parts Executive Order Parts are aftermarket parts that ARB has evaluated and determined do not adversely impact emissions, and thereby are granted an Executive Order (EO), which allows the part to be sold and used on specified automobiles. Any aftermarket exhaust system that replaces or otherwise impacts emission control equipment, including catalytic converters, requires an EO to be sold and used on a automobile used on or off a public highway.

(3) Competition Use Only Parts may not be sold or used on an automobile that is used on or off the public highways other than those automobiles used exclusively for competition. Competition Use Only Parts are aftermarket parts that replace or otherwise interfere with the operation of an emission control device, such as a catalytic converter or oxygen sensor, and may be sold and used on an automobile that is used only for closed course competition.

THESE PARTS ARE LEGAL FOR USE ONLY IN COMPETITION RACING VEHICLES AS DEFINED UNDER CALIFORNIA LAW, AND ARE NOT LEGAL FOR USE IN ANY OTHER MOTOR VEHICLE. California law defines a “racing vehicle” as “a competition vehicle not used on public highways.” (Calif. Health & Safety Code 39048) These parts may only be used on competition racing vehicles operated exclusively on a closed course in conjunction with a sanctioned racing event. Competition-only motor vehicles may not be driven to a racing event on a public highway and must be transported on a trailer or other carrier. USE OF THESE PARTS IN ANY OTHER VEHICLE MAY SUBJECT YOU TO FINES AND PENALTIES FOR VIOLATION OF FEDERAL AND/OR STATE LAW, WILL VOID YOUR WARRANTY FROM BrenTuning, LLC AND CAN VOID YOUR VEHICLE’S WARRANTY. It is your responsibility to comply with all applicable federal and state laws relating to use of these parts, and BrenTuning, LLC hereby disclaims any liability resulting from the failure to use these parts in compliance with all applicable federal and state laws.

SATISFIED CLIENTS MAKE US HAPPY

  • “ Professional, knowledgeable and friendly. The BrenTuning team delivered excellent work and answered all of my questions. Their E-Tune service was a great experience and I would do it again. ”

    Chris Cioffari May 12, 2017
  • “ I highly recommend Bren Tuning. I've gone to see them twice with my 15' STI, first time after getting the access port and installing an intake and last week for GS downpipe, N1 cat back and of course another tune. Couldn't be happier with the results, car runs and sounds even better that I expected. ”

  • “ Had my 2010 335xi serviced here and I have nothing but good things to say about these guys. I had a lot of work done at once and it all came out perfect. Definitely recommend and you are guaranteed to be pleased with the results! ”

    Dariush Vafaee May 12, 2017
  • “ Just finished getting a e-tune on my 15 wrx and its amazing! Car runs so smooth and has so much power! I highly recommend them for anything you need for your car. I will be taking the 3 hour trip to get more work done. Customer service was great and speedy! ”

    Chris Hernandez May 12, 2017
  • “ I've been working with Bren for over a year now on my 2015 STi. It's not often I find a shop that shares my perspective when it comes to my car. Down to earth, "REAL' car-guys. They treat my car as if it were their own, and do their best to exceed my expectations every time. I also use them for maintenance on my car. Its where I prefer to bring my car, because I know nothing will be overlooked. And when track days come around , they'll be there too, to help and advise me every step of the way. I cant ask for anything more than that. ”

    Mar Salisbury May 12, 2017
  • “ Bren seriously took his time with my tune and it was absolutely amazing. Really worked hard to get it right and when I saw that dyno sheet I almost wanted to cry from joy, power curves were amazing and he ended up getting me perfectly to 337hp 337tq. I couldn't be more happy with numbers like that. Not only was the tune amazing, but the customer service. I had a 330 spot on a Friday, ran into some trouble getting there and wasn't able to arrive until 45 minutes after my appointment. I simply called them, and was told exactly this "hey man no worries we understand, get here whenever you can and we'll make sure we take care of you tonight." To me... That says it all about Bren right there. Excellent work, you've got a lifetime customer here. ”

    Jamie Pereira May 12, 2017
  • “ Had an install and protune done with Bren and the team on my 2015 WRX. Car put out absolutely stunning results! Bren really took time and patience getting the tune right. After the dyno tune he sat with me for a ride along to make sure everything was to my liking. Great team, very friendly, down to earth and professional! ”

    Vahe Keshishian May 12, 2017
  • “ Got my 2015 Wrx e-tuned by Brentuning and could not have been any better. All my questions and concerns were answered in a timely fashion along with the tuning process itself. Car is now so much more drivable with the rev hang removed, pulls much smoother, and pulls way harder all the way to redline. ”

    Perry Alpert May 12, 2017
  • “ Hands Down...The BEST Customer Service Ever. I have a Stage 2+ 2012 STi and worked with BrenTuning to have a Protune added. The car feels completely different. There is significantly less delay in response time. The boost holds much better and is a much smoother pull. I can also feel a significant gain in tongue. Their response time was incredible though. Communication was done through email and the turn around time was instantaneous, literally felt like texting. I would highly recommend BrenTuning for great work and outstanding customer service. ”
