Who are we?



Lou’s Muffler and Brake in Hanover, Hyannis, Plymouth, Quincy, and Westport are independently owned and operated custom exhaust shops specializing in the fabrication of stock replacement and performance exhaust systems. We pride ourselves on our fabrication and welding skills developed through years of training and experience.  These 5 shops share philosophy and employees.


First thing you will notice is that we don’t charge you anything to look at and diagnose your car’s issue. At many shops you will be hit with a standard $100, or more, “diagnostic fee”.   Then there is the exceptional value pricing of our work. We keep the price low and quality high because we start with raw materials; straight 14 gauge pipe, mufflers, and hangers. Our experienced employees fabricate your exhaust system to your vehicle specifications.

The advantage: a perfect fit and cost savings to our customers. National chain shops buy pre-bent exhaust systems from their franchisors at very high prices and pass this cost to their customers.   Lou’s of Hanover, Hyannis, Plymouth, Quincy, and Westport do not have middle men—so our prices are typically hundreds of dollars less.

1) We fabricate our own exhaust piping and repair parts keeping the cost of the replacement parts much lower

2) There are several shops that buy materials together in bulk further reducing the prices on materials

3) We can cut and weld replacement parts, such as catalytic converters, into stock systems saving the customer hundreds or even thousands of dollars

4) We cut out the middleman.

On most typical repairs we can save you, the customer, anywhere from $100 all the way up to thousands of dollars. A perfect example of this is replacing the front flex pipes on an Audi A4. These parts have a catalytic converter built into them. To replace both flex pipes here it would cost you under $400.00 for BOTH sides. The factory part, unistalled, costs $700 per side. Aftermarket you can typically get them for $325.00 per side. By fabricating this ourselves we can save you over a thousand dollars.
