Franklynn Auto was extremely fast and professional. Did not try to upsell me and provided exactly what I needed. When an at home DIY transmission pan replacement and fluid replacement went wrong, I decided to tow to Franklynn’s due to the amazing amount of reviews. I’m a cheapo and love to do all of my own vehicle maintaining. One bolt sheared off and Franklynn’s was able to help fix my mistake. While it may have been just good timing, I was able to get in the next morning and had my truck back within 8 hours. Thank you so much for your courteous phone calls on updates and findings. The work was excellent and mechanics informed me of everything they did as well. Thank you thank you thank you for getting my daily driver to me back quickly!!!Posted on Google![]()

I think, one of the best auto shop repair experiences I ever had. I went to a dealer who charged $250 for diagnostics for a seatbelt that was on back order with no clue when the repalcement would be available and a liftgate motor they said needed to be replaced. I declined. I know, my mistake to begin with. I took it to Franklynn and talked to Steve. On the same day, Steve found a replacement seatbelt a shade off color, but could get it installed soon for less than half the price of the dealer. I know, dealers must use OEM parts. For the liftgate motor, the technician found a technical service bulletin that described re programming a computer module. That fixed the problem for less than 20% of the dealer estimate. As for honesty, the technician drove the vehicle and thought he heard a noise in the rear suspension. I authorized investigation and Steve called back to say it was a can under a seat that was making the noise. They could have come up with the doohickey connected to the thingamajig that needed replacement. They didn't. They are professional, efficient, honest, and fairly priced. I will be back and highly recommend this shop to my friends and family. The address is South Broadway, but they actually front Southpark Plaza just north of Southpark Dr just north of Goodwill.Posted on Google![]()

I am a new customer to Franklynn Automotive as of October 2026 on the referral of my neighbor, as my longtime auto shop closed their doors. My first visit was for a routine oil change for my 2013 Honda CRV. Upon further and thorough inspection, they alerted me to the immediate need for rear brakes/rotors. They were able to squeeze me in a few days later and complete the job. I was worried that I would be unable to find a reliable and honest comparative auto shop but I have found it in Franklynn! Steve and Jodie at the front end are so helpful, friendly and knowledgeable. Good service is still a thing and I couldn’t be happier!Posted on Google![]()

Steve, as usual, was very organized and ready for my appointment at 8:00 AM Monday to replace my brakes. He informed me of the changes on brakes pad composition and if I experienced any noise issues to come back and they would recheck everything. I highly recommend Franklin Automotive for all your auto service needs. Rick GerberPosted on Google![]()

This is a gem of automotive specialist from Steve Waggle on the front desk to each technician in the shop. I wish I give them all credit. For myself my focus on brake repair that has taken over a year to completely figure out. Twice at Dealer in 2 states. Towing and feeling safe since I had a failed brake master cylinder that brake upgrade was not completed on 2015 Dodge Truck. Franklyn Automotive took notes, listened, drove vehicle at my recommendation to simulate truck not being to stop. A nd Voila "they figured it out as a failed Power Braker Booster". They also did all the items on my list from premium oil changes, repair faulty wiring in Topper, tire rotation, etc, etc. Please give these folks your business. You will not be sorry. Glenn

Frequently Asked Questions:
Common warning signs include unusually loud engine or exhaust noise, rattling underneath the vehicle, a strong exhaust odor, reduced engine performance, visible rust or damage, and a check engine light. A hissing or tapping sound may indicate an exhaust leak, while a deep rumbling noise can point to a damaged muffler or exhaust pipe. Because several vehicle problems can cause similar symptoms, the complete exhaust system should be inspected before repairs are recommended.
An exhaust leak should be inspected as soon as possible. The exhaust system is designed to direct combustion gases safely away from the passenger compartment. A leak may allow harmful fumes, including carbon monoxide, to enter the vehicle under certain conditions. If occupants smell exhaust inside the cabin or experience headache, dizziness, nausea, or unusual fatigue, they should exit the vehicle, move into fresh air, and avoid driving it until the problem has been evaluated.
A vehicle may become louder because of a damaged muffler, cracked exhaust pipe, failed gasket, loose connection, broken hanger, or exhaust-manifold leak. The location and character of the sound can offer useful clues, but sound alone cannot confirm which component has failed. A professional inspection can locate the leak or damage and determine whether the affected section can be repaired or requires replacement.
The exhaust system is the complete assembly that routes exhaust gases from the engine to the rear of the vehicle. Depending on the vehicle, it may include the exhaust manifold, catalytic converter, oxygen sensors, pipes, resonator, muffler, hangers, clamps, and tailpipe. The muffler is one component within that system. Its primary purpose is to reduce the noise created as exhaust gases leave the engine.
Yes. Problems involving oxygen sensors, the catalytic converter, exhaust leaks, or related engine-management components may trigger the check engine light. However, the light can indicate many different issues, so the diagnostic trouble code should not be treated as proof that a specific exhaust component has failed. Proper diagnosis may include scanning the vehicle, inspecting the exhaust system, testing sensors, and evaluating engine performance before recommending repairs.
Exhaust components are exposed to heat, moisture, vibration, road debris, and changing temperatures. Over time, these conditions can cause corrosion, cracks, loose connections, failed welds, or damaged mounting hardware. Littleton drivers may also encounter snow, ice, potholes, and winter road treatments that place additional stress on components underneath the vehicle. Short trips can contribute to internal moisture accumulation because the exhaust system may not remain hot long enough to evaporate condensation completely.
It can. A restricted catalytic converter or severely damaged exhaust component may reduce engine power, acceleration, or fuel efficiency. An exhaust leak near an oxygen sensor may also provide inaccurate information to the engine-management system. However, poor performance and increased fuel consumption have many possible causes. An inspection and diagnostic testing are needed to determine whether the exhaust system is responsible.
No. Although muffler damage is a common source of excessive noise, the problem could also involve an exhaust pipe, resonator, gasket, manifold, flex pipe, heat shield, hanger, or connection. A loose heat shield may create a metallic rattle, while a small leak can produce a ticking or hissing sound. Inspecting the entire system helps avoid replacing a muffler when another component is causing the noise.
That depends on the location, extent, and cause of the damage. Some isolated problems may be corrected by replacing a gasket, clamp, hanger, or damaged exhaust section. Extensive corrosion, multiple leaks, or internal failure of a muffler or catalytic converter may require component replacement. A technician should inspect the system before determining the most appropriate repair. Replacing the entire exhaust system is not automatically necessary.
Franklynn Automotive provides muffler and exhaust-system inspection, diagnosis, and repair for drivers in Littleton, Highlands Ranch, and nearby communities. The team can evaluate excessive noise, exhaust odors, rattles, check engine lights, damaged pipes, catalytic-converter concerns, and other exhaust-system symptoms. Scheduling an inspection early can help identify the affected component before the problem creates additional noise, performance concerns, or potential exposure to exhaust fumes.
