Great experience so far. The guys are very helpful and happy to work with your needs. I brought my C7 Corvette for a muffler delete and they immediately worked with me on the best way to go about it. Looking forward to seeing and hearing the final result.

I took my Q50 in for a muffler delete and had the guys install my axle-back pipes. They did so very quickly, professionally and were able to easily sort out a manfucturing issue with the pipes. The exhaust looks great, sounds even better! Definitely will come to them again in the future!

Collins Mufflers did a great job on my 2018 GT Mustang. I called a couple of places to get a resonator delete and install an H-Pipe, Collins was the best price. Alex was professional and friendly, he went the extra mile to get it just the way I wanted. Now my stang sounds like a beast!

Unbeatable customer service! I've rarely seen a business with this sense of integrity and genuine helpfulness. Thank you so much for your help.

Really informative and not pushy. My 2011 range rover had hitch added, so a hardwired brake controller isn't possible.. they gave me a bunch of other wireless options to think over. Nice guys.

I just got a 2 inch receiver hitch from Collins for my brand new Telluride.

I love the finish of their job. They are very professional and knowledgeable about the hitch. Also I like their price too which was very reasonable. If I need another hitch job done, then I will come back here.


David P., Irvine, CA Via Yelp Testimonial

Came in today met the previous owner and the new owner. Both are very respectful, friendly, and clean. They made my Mercedes s550 into a beast sounds amazing and looks amazing with my new exhaust tips. I will be back again for sure and would recommend anybody to come here. Great customer service and fast to get the job done!

Randy is the owner. He has gone above and beyond fixing a very complicated issue with my Cat Converter where no replacement part was available. This garage is honest and hardworking.

Gabe A., Aliso Viejo, CA Via Yelp Testimonial

Randy and his team are awesome!! Great quality and outstanding customer service! I brought my classic truck in for exhaust work and they were able to accommodate the short notice and provided a great price! The truck was ready within a few hours and sounds and looks great!! Highly recommend Collins for anyone looking for customer exhaust work, especially on a classic vehicle. They take pride in their work and and ensure their customers are satisfied!

Randy and Alex took care of my quickly. I stopped by Saturday morning for exhaust work. Randy said to come back in two hours. We returned at 11am and had them do a muffler delete, which they did expertly and quickly. My new exhaust note sounds awesome and looks great with the chrome rolled tips.

Props guys. I am very happy.

My husband brought in our new Tahoe because I wanted the V8 to sound like, well, a V8. They were willing to see us within the hour and when he pulled up the vehicle was on the lift within 2 minutes being worked on! They promised him 45 minutes until complete. They had it done in 40 and delivered. The Tahoe sounds exactly how I wanted and how they promised it would. Very pleased with Randy Collins and crew.

Kelly Simmons Via Google Review

I took Randy a very tough job, a complete exhaust system on a 1930 Ford with a 1957 Chevy engine. Space under the car was very limited and every portion had to be custom made. In the middle of that, Randy's No.2 guy was going through a divorce and was clearly not at his best.

The point of my review is to verify the "character" of Randy. He was determined to make me be satisfied, and went to every extra effort to make that happen. He succeeded! I am very pleased with the whole job, and especially appreciative of Randy for making sure I was satisfied.

Walt L., Mission Viejo, CA Via Yelp Testimonial

Alex and his boss were great ...they fixed my mother's hospital bed railing weld in no time and with a very reasonable price. Next time I need welding of any type, I know where to go.

Highly recommended local shop for local folks like me.

Mohsen Mohseni Via Google Review

They did a fantastic job on my car! I went in asking for a new muffler system on my 2015 BMW 428i Coupe, and they replaced it perfectly and at an amazing price. Not too loud, but definitely noticeable. Thanks Collins Muffler & Hitch!

Elliot M., Ladera Ranch, CA Via Yelp Testimonial

I came in here to have a front muffler deletion on my new Lexus NX300 and I am very pleased with the work that was done on my car. Their recommendation to create the exhaust sound I wanted was spot on, the welding was fantastic and my car exhaust now has just a slightly menacing growl with a beautiful base and no drone. These guys know what they're doing and know what needs to be done to get you what you want without going overboard. People hear the sexy growl of my car now and I won't ever get a ticket for having an illegal muffler.

Jarrod Fisher Via Google Review

Took my truck to Collins Muffler based on good reviews online and I was impressed with their expertise in installing a new muffler and pipes. The new setup is better than the original. If you are looking for a good and honest muffler shop this is the place. Owner Randy Collins will take good care of your vehicle.

Andy S., San Clemente, CA Via Yelp Testimonial

This place is great They are simple to work with Great prices, very knowledgable, great products and finished what I needed in like and hour. It took me longer to drive here than to get my exhaust redone and they worked a great deal. Nice friendly guys no BS kinda place. I will go back for more business there for sure! And most importantly my truck Sounds so killer with flow-masters they put in!

Richard Gamboa Via Google Review

Highly recommend this place to anyone who is in the area and needs anything done. soooooo friendly and good customer service and very quick and precise job!!! I’ll be back forsure with more work for them!! Wouldn’t trust anyone else with my car!!

Steven Rogers Via Facebook Review

I had purchased an OEM Acura trailer hitch online for my car, and was looking for someone local to put the hitch on. I called several stores in Orange County, and I was quoted a price over the phone by Randy. I brought my car in, they installed the hitch perfectly. Service was fast, and the best price I found around Orange County.

Best customer service Alex did an amazing job on my 2008 e92 m3 muffler i would highly recommend this shop in and out quick and quality work thanks again Alex!!

Jebby J. Irvine, CA Via Yelp Testimonial

This place is awesome! Got my stock exhaust replaced with a carbon made muffler on my Mercedes. Super quick and super simple work here. Great job! Highly recommend

Hayden L. Mission Viejo, CA Via Yelp Testimonial

I've been coming here since I was 17 years old. They are always professional and courteous. But best of cars have always sounded and performed amazing!! Shout out to Randy the owner. He knows his stuff

JD R. Fullerton, CA Via Yelp Testimonial

I took a fuel tank bracket that had broken on my C4500 down there to see if they could weld it up for me. They were busy but still took the time to do the job. He sanded the part clean, welded it back together and painted it black. I was expecting the normal 1-hour charge even for the small job but walked out happy about the quality of work and the price paid.

I will be taking my truck here when I make the changes to the exhaust.

Bryan C. Mission Viejo, CA Via Yelp Testimonial

Randy, Alex and Nelson are great I took my 2013 M3 to randy and he did some custom exhaust work for me at a great price and my M3 sounds unreal. I would recommend Collins to anyone in the Orange County area. Make the drive its worth it.

Sean J. Newport Beach, CA Via Yelp Testimonial

I called one morning to get a cat back muffler installed on my tundra. He said I could bring it by that day and he'd have it done the same day. I brought it by around 2, it was finished by the time I was off work at 5. For quick service and great quality, Collin's muffler charged a very reasonable price. I'd recommend this shop to anyone with muffler/exhaust needs.

Toan D. Trabuco Canyon, CA Via Yelp Testimonial

Great experience. Dropped off car in the AM. Hitch was installed looks great and attention to detail was amazing. Overall highly recommend then V's the dealership. Saved me a ton of money and now I have a hitch that works and looks great!

TJ Q. Lake Forest, CA Via Yelp Testimonial

I came here based upon the reviews and I'm really happy with the service, quality, friendliness, and pricing. I came here to replace the tow assembly on my 1977 truck. Thanks!

Michelle D. Rancho Santa Margarita, CA Via Yelp Testimonial

Great Pepole to work with and great prices they have done few of my cars this is the only custom exhaust place I will go to thanks randy

Spencer C. Orange, CA Via Yelp Testimonial

I highly recommend Collins Muffler and Hitch! The owner Randy was knowledgeable, honest and great to work with. I had new brakes installed on my Landrover. I chose the top of the line rotors and my bill was still less than what I was quoted by other mechanic shops.

I give Colling Muffler and & Hitch 5 plus stars!!!!!!!
