Hello, I’m John!

Hi, I’m John Brockman. I have lived in the Joplin area for 46 years. I started working in the automotive industry in 1991.  I began my career in exhaust system repair in May of 2000.  I strive to provide the highest quality product and workmanship in the industry.

Brockmans Muffler

Custom Exhaust Systems!

Custom exhaust systems built to your specifications while you wait!  If you can dream it, we can make it happen.  Does that new vehicle exhaust just not match that new vehicle style?  We can make the sound match the machine.  Are you rebuilding a classic auto?  We can build any style and sound you want for your baby.


A Lifetime Warranty is provided for all Mufflers (not to include labor) and is offered to the owner whom purchases it for the vehicle the muffler is originally installed on. All parts and labor from Brockman’s Muffler LLC are warranted to be free from defects in material or workmanship from date of purchase from Brockman’s. Any necessary corrections or repairs made during this warranty period may be made by appointment, and only with the presentment of the original receipt for the muffler. Additional parts and labor may be required which were not on the original order, and will be billed at the rate charged by Brockman’s Muffler LLC.  This Brockman’s Muffler Lifetime Muffler Warranty only extends to normal wear and tear on the muffler and shall not include or apply to any failure due to negligence on behalf of the owner or the owner’s agent or willful abuse, fire, theft, or wreck or collision. Brockman’s Muffler warrants that any goods provided are merchantable goods of that kind and are fit for the ordinary purposes for which such goods are used.
