They were open on Sundays. Good price. Fast service.

Very fast service. Most definitely recommend.

This place is out of business. I call no answer, drove down there doors are closed

No. Just no. Do not even make an attempt. You will be sorry.

Place is good A crowded area because of other shops but did a good job

Took my daughters car in today..it was making a loud sound..Luis helped us..super friendly very helpful and informative, Very reasonable!! Will reccomend and return if needed!!

Terco mufflers is the best place to go for your catalytic converter repair. Luis is awesome. I always go back to this shop because they are trustworthy.

Friendly & Cheapest deals plus fantastic job well done! I recommend. 👍👍

Not open on time. Opens at 9am. I was there at 9:05 on Monday, 12/21/20. I left at 9:30am and it was still closed. I took my business somewhere else and passed by here at 10:45am and it was still closed.

Best deals around 👍👍

The best shop around! They worked on my 67 Mustang, RSX, and two BMWs over a period of 7 years and its the same. Reliable, and efficient.. this is the only shop that I trust to work on my vehicle!

Was stranded on freeway call them and they where there fast. Also great pricing.

Do you guys do straight pipes

I had a bad experience, they extended the pipe like I asked. It was good until i went by a dip (10mph) and it fell off. Great people and great service they helped me right away, just unfortunate it fell off on me I only gave it 5 star rating because they treated me right and helped me right away.

I had a good price on my cat back system and the job was done right thank you tercos

If u want high quality work for a reasonable price I recommend Terco mufflers one of the best shops in pomona

Replaced catalytic. Installation was acceptable. No seating area.

Great job, The best price in town. Very professional

Fair pricing, honest workers, and wonderful customer service.

Nobody answers. Business is closed
