    The finished product, nice exhaust tip and sounds good.
    Pedro F.

    Ernie and the crew had my 2001 F250 diesel truck up and ready in a few hours. My truck had what can only be described as a tin can at the end of it which made it sound like ish. Ernie made some recommendations based on the fact my dad drives this truck daily to and from work and I didn't want it loud and more obnoxious than it was. The finished result was awesome. Muffler and exhaust tip look better than factory. The sound is just right

    What can I say, when it comes to getting work done, Ernie is my go to. Guys been here for Years and knows his stuff. In and out. Quick and way and I was ready to go! He's fair on pricing., reliable work, and knows a few things about cars as well. I'll be having him do my truck next.

    The Muffler Doctor, where they won't necessarily put all the bolts back in and, when they can't find your bolt and see that the gasket is broken, will glue the flange as a quick fix. I'm impressed! Yeah, not really. There is no excuse for not doing it right the first time.

    IF YOU NEED EXHAUST WORK, DON'T GO ANYWHERE ELSE. I was recommended by one of my best friends to come here and of course I had to go the first chance I got. I am so glad we have stumbled upon this exhaust shop. Great people, stellar customer service, speedy service and unbeatable prices! I came here to swap my OEM resonator with an aftermarket Vibrant bottle-style resonator and the price was only $50 out the door. The work only took about 25 minutes and the owner was super friendly and understanding while I was filming for my Youtube channel. I was able to film and watch the whole process safely. Luckily for me this shop is close, but honestly speaking even if it were 20-25 miles away I'd make the drive down knowing how great the work and their service is. I doubt this will be my last time here for some exhaust work so I'm looking forward to my next visit! Be on the lookout for the video to get more in depth footage of the shop and the work that they did. I left the shop ecstatic and ready for more exhaust work to be done!

    Came here to have a J-Pipe installed on my 3 inch catback exhaust to kill my freeway drone in the 3k -4k rpm range. I did all my calculations at home, brought the Vibrant piping needed for the job, and asked Ernie if he could fab up the piping for me. I was in and out in less than 2 hours and paid a very reasonable price. Welds look good and the shop did exactly what I asked them to. Would 10/10 recommend to any friend needing custom exhaust work done to go here.

    Went to "da shop" yesterday to get my TRD Muffler repositioned because Advance Muffler Shop of Riverside didn't do a good job. However their rating would be on their Yelp page, not this one. Ernie saw the exhaust set up and immediately asked "Where'd you get this done?" And "Did the shop owner really leave it like this?" Big time SMH. I had called and made an appointment for me and my friend and we drove to Montclair and arrived on time. My buddy got my old set up on his car and I got my exhaust repositioned. We were both charged fair and reasonable prices! Just wanted to make an update review to show the shop some love! Never a disappointment coming here. Third Review: 01/17/20 I'm moving on from a 2006 Toyota Matrix (1ZZFE) to a 2003 Toyota Matrix XRS (2ZZGE) and I've decided to make my daily bone stock again! At first I was debating whether to save a trip by going to the local shops in my area, but I saw the reviews and immediately considered staying with the OG. Uneven welds and a lot of money spent is TOTALLY NOT WORTH IT. Scheduled to meet with Ernie today in the morning an hour after opening. I had to wait a little bit but that doesn't concern me at all. I conversed with another gentleman there about his lowered 2001 Suburban! Will definitely come back next time when I get the project car. Always a great experience here at the Muffler Doctor. Big thanks for their services!

    Amazing service.. I called mid week spoke with Ernie. Appt next day!! - nice!! I go there hes like muffler delete and add some straight pipes? Yes sir!! Drive it on back I'll meet you around back. They put it on the lift immediately. They have low ramps for lowered cars too. 2 guys jumped on to help. Started cutting out the stock mufflers. Measuring for the straight pipe. Lined it all up nice bends in the pipes (photos soon to come) and welded tight. Car Sounds awesome!! I payed cash. Was in and out in less than an hour. I will recomend this place to others!! Fast, detailed, & extremely reasonably priced. Thanks Ernie!! Shop owners cool too!!

    Called them 9am in the morning and asked if they had any open slots for the day for a resonator delete. Got to the shop at 10:30 and they finished everything by 11:30. Shout out to Ernie for being super straight forward and the fast service! Would Highly recommend!

I took my car to them and met with Rocky, the manager. From the moment I walked into their facility my first impression was that he runs a very clean shop.
