1989 Ford Mustang:I will never go to another exhaust shop again, Extreme Muffler Conversions is the best and most helpful exhaust shop I ve ever been to. I was very very particular with how I wanted my exhaust system set up because I constantly work on my car and they put it exactly how I pictured it, they even added paint at the end to all the welds. Such a high-quality shop for such amazing prices.

I highly recommend this place. I had a BORLA Cat-back system installed for my 2023 Camry XSE. I was there to see the whole installation. I was really satisfied with Hectors labor because he cares for his customers by demonstrating how the simplest modifications during installation can make a HUGE difference. As soon as i turned on the vehicle, I was greeted with the loud sound of power, which put a huge smile on my face. I rate this place 10/10 for the good vibes and a job well done.

Hector was able to fix my rear frame hinge from the previous owner's miserably failed attempt to rethread. Bring your welding needs to Hector.

Extreme Conversions & Mufflers is a hidden gem for anyone seeking efficient and reliable service for their vehicle's exhaust needs. Hector and his wife, Rosaura greeted me with respect & I felt very welcomed coming to this place. They genuinely care about their customers' satisfaction.I highly recommend them to anyone in need of prompt and reliable service. Their commitment to excellence, combined with their friendly demeanor and top-notch craftsmanship, make them the go-to destination in Riverside for all your exhaust or muffler needs. I'll certainly be returning for any future upgrades or maintenance.

I had a new muffler put on my 1970 VW Bus and Hector did an amazing job! He couldn't find a replacement gasket coming off of the headers so he made one. Hector also added a muffler mount on the frame. I got a next day turnaround to boot!The Bus sounds amazing and runs even better, thank you Hector!

Hector treated me amazingly along with his amazing wife. Amazing customer service, was honest about his work and provided transparency for me. He allowed me into his shop and showed me what he was doing and why he was doing it. I came in for an exhaust leak, not only did he fix it, he informed me that my cats were in great condition and didn t try to upsell me any parts. He gave me the old parts to also prove his work. He was truthful and I will 100% be a returning customer. �Gracias por tu arduo trabajo H�ctor!

Thank you Hector and Rosario! They were extremely professional and great about working with my schedule to get me back on the road. The work preformed is impeccable and I feel much safer now that my catalytic converter covers are installed. Thank you for going above and beyond. I will definitely be recommending my friends and family.

This is literally the best place to go. I had taken my car after I called ahead to make sure they could fit me in. They said yes and told me the job would take around 2 hours. Not only did the job take only 45 minutes to a hour, when I got there they were so kind they gave me water made sure the AC was on and even switched on TV. The main guy Hector walked me through everything, I mean everything and told me exactly what he was doing. The absolute best place with 2 of the nicest people I have ever met. I had called other places ahead to find the right price and these guys have the best prices in the game. Don t waste your time calling other places and come here.

Shop owner Hector does great work at a fair price with awesome customer service. He will give you a price quote than starts doing his magic, no rush job, takes his time to measure twice and cut once. Had to cut rear exhaust pipe and than weld the muffler tips on. they came out exactly perfect and solid weld all around.I would recommend Hector's shop to do any exhaust work that he works on personally.Nice family owned business with his wife by his side.Thanks again

There is no doubt in my mind that this shop is the best in Riverside. I went to 6 different muffler shops as well as the Ford dealership to get quotes on having my catalytic converter replaced. They all gave varying yet similar prices but only one took the time to actually put my car up on the rack and inspect it before I even hired him. The owner/mechanic is Hector and let me tell you he is the nicest guy I ve ever met at an auto shop.Hector and his wife Rosaura go above and beyond to make you happy and he does excellent high quality work. He even fixed a part of my bumper that was pushed in and he fixed some heat shielding underneath the vehicle and didn t charge me a dime for either. Absolutely amazing!Stop looking around and just take your vehicle here, you will NOT be disappointed.Thank you so much Hector and Rosaura!Service: Exhaust

Called to make an appointment and came in. Super nice people; Hector and his wife are very accommodating people. I asked Hector to do a muffler delete and reinstall the factory exhaust flap on my 2020 BMW M340i. Did it no problem and now it sounds the way I want it to. 10/10 would recommend this shop over everyone!Service: ExhaustService: Exhaust
