  • Muffler & Pipe Advice - Never Give Up!
    I heard a saying long ago that, “if you want something that you have never had, then you have to do things that you have never done before.” This is so true in life, let alone business, but wedged in between those two lines is a never-give-up attitude.
  • Sound & Performance Go Hand in Hand
    Some motorists add performance-exhaust systems to their vehicles for extra horsepower and torque, while others just appreciate that aggressive tone that goes with it – and of course, some like it for both reasons. There’s the revving of the engine at the stop light and the burst of power that goes with taking off with their right foot to the floor.
  • Outsourcing - One man’s headache, another man’s joy
    We are all looking for ways to build our business. One sure way, I found, is to approach fleet managers and other non-competitive shops.
    All technicians have their most hated jobs and usually on a particular type vehicle. So, that is where you can become the “aspirin” for their headache jobs, but first you have to find out what that problem job is.
  • Muffler & Pipe Advice: Like a Glove!
    It was in the late ’90s that I had the experience of installing a set of Corvette headers manufactured by B&B (Billy Boat) Fabrication. I was doing work for a local Chevrolet dealership. It was the kind of dealership that was thinking outside the box. This dealership would customize your Corvette prior to you picking it up. One of the things they would do is have us install B&B headers.
  • Muffler & Pipe Advice - Mission Impossible: Pancake Problems
    Some years ago, California had some emissions rules that did not make much sense. I am not talking about emissions systems, such as catalytic converters, but it applies to the catalytic converters and rules that were set up.
  • Where is the Passion?
    Just recently, I received an email from one of my old friends and co-workers, now living in New Mexico. Stu Ehrich and I go a long ways back to when I first got out of the service and planted myself in San Diego. I have lots of respect for this man and he brought to my attention that there seems to be a loss of passion in our industry! I thought long and hard as to why and came up with several reasons.
  • Universal Cats Aren’t Universal Anymore
    It was a typical Monday morning in August. The temperature was kissing 90° and the humidity wasn’t far behind.
    Then she pulled in. She was expensive looking with all the bells and whistles that made you want to look twice at her – and she was still in her prime. It was a 2009 Acura MDX, and the dame behind the wheel was NOT happy. She was barely out of the car when she eyed me with disgust. “The light’s on again,” she said.
  • Muffler & Pipe Advice - Just a ‘Muffler Guy’
    So, I am sitting in a management program with Bob Spitz as our instructor. My wife Marilyn and I are the only automotive exhaust shop owners who have attended his training class, so Bob, with his sense of humor, referred to me as the “muffler guy.”
  • Muffler & Pipe Advice: Building a quarter-wave tuner
    First off: What is a quarter-wave tuner?  All of us in the exhaust industry have either experienced that harmful drone in the cabin of our vehicle, or the cabin of our customer’s vehicle, especially if the vehicle has an aftermarket exhaust system. A quarter-wave tuner, or as some call it a quarter-wave resonator, is a device that helps eliminate that nasty interior sound that we call a drone.
  • Drivers, Start your Engines!
    Many of us are waiting for next month’s Undercar Digest to see all the hard toil that techs have put into their project vehicles for the “Magic Machines” section. Most of these vehicles are in pristine shape and only venture outside the garage on warm, sunny days.
  • Say ‘NO’ to Crack!
    Crystal lite, fine; Diet Coke, that’s OK as well; but crack, absolutely not. How many times have we heard the saying “No to crack.”
     
    Of course, I am not giving a lecture, but talking about those darn cracks near our catalytic converters and oxygen sensors. Getting those trouble codes directing you to a lean condition, may be a little misleading in some cases.
  • Muffler & Pipe Advice: Backpressure or Heat
    My computer spell check tells me that backpressure should be spelled as two words – back pressure. But my editor tells me that my spell check is wrong and to keep at as I always have. Regardless of how you spell it, “backpressure” is necessary in an exhaust system.
  • Muffler & Pipe Advice: Universal Catalyst vs. Direct-Fit
    “To build or not to build, that is the question.” Here in California, we have stricter emission laws (as if no one knows!). The California Air Resource Board (CARB) has really simplified its website to help our shops find California-approved aftermarket devices, like headers, intake systems, carburetors and catalytic converters. As an exhaust-only shop, we are concerned with upholding the laws relating to our business, so using a California-approved catalyst is high up on our list.
