Apparently, you hired your two dumb ass nephews that now have restraining orders out against them because driving a truck with your stickers all over it and then on video that was given to the cops today they yelled yeah lose our uncle so they're making you and your business look atrocious and this is going to court. They're getting harassment charges pressed against them and I just wanted to let you know that these are the assholes that are going to be going through your cars and these are the people that you're gonna be leaving your stuff with. I have a nine-year-old son with severe autism and serious sensory issues and we ask them not to do break stands and spin outs and burnouts in front of our house one day because it throws my son into a four hour meltdown and they took that on as a dare so they've been doing and at least four times a day and now that we finally got it on camera now they're fucked. You might wanna talk to them about this or at least tell them not to scream out loud on a video that's gonna be played in court and that was given to the police that yeah that's my uncle he owns a shop. What do you wanna do about it? This is what I'm gonna do about it. I'm gonna call multiple times tomorrow and make complaints and I want something done about your nephews and they're friggin harassment on me and my child. I have a video of him literally jumping outside his window ready to attack me. Because he said I was harassing him, but he was the one that was parked in front of my house and I was standing on my porch. They are aggressive and scary and I'm scared for my life. That's who works there and these dingbat's uncle is the one who owns the place so depending on how he handles this he could be just as bad as them let's hope not though. But there are so many loose custom shops go anywhere else. read more

First there is the very confident and accommodating Manager Mike! He quickly surveyed my Jeep and had his welding wizard Frank jump right on the job! Meanwhile, Doug took my information and handled the office work! Expeditiously! These men were courteous, knowledgeable and professional! I was there for a 9:30 A.M. appointment and was on my way by 10 A.M.! I have had to wait for as much as 5 hours for less work at other repair shops and never was treated with the respect and friendliness I experienced at Lou's! If I could give Ten Stars I would! My bill was extremely affordable for the high quality parts installed! I will never go elsewhere after this OUTSTANDING EXPERIENCE! read more

I was recommended Lou's Custom Exhaust by my friend because my exhaust was busted. I drove over there and left and in within 40 mins I had a brand new exhaust when I was expecting it to be done by Monday. (It's Friday) Great people. Friendly and fast efficient and professional. I Highly recommend them. Frank the manager was the best! He treats you like your his family. The price was great too worth every penny. These guys are true professionals and even though they were lacking help they did a fantastic job. They both deserve a raise. I will recommend this place to all my friends and family. Thank you Lou's Custom Exhaust! And thank you Frank! read more

I had some brake issues on my Jeep Liberty so I called Lou's custom exhaust in Portsmouth, NH.... and I couldn't be happier with the job they did for me! Frank was the technician that worked on my brakes, and he kept me completely informed of everything, from the initial "test drive" to the final "diagnosis". He was concerned not only about the brake job he was performing but also GENUINELY concerned about my safety after the fact. I am sooo impressed with the job he did as well as the final cost to me that I am telling everyone who will listen to me...... GO TO LOU'S CUSTOM EXHAUST FOR YOUR REPAIR NEEDS!!! They are just THE BEST!! read more

Would highly recommend Lou's in Portsmouth N.H..Very pleasant to deal with and did a great job on replacing the manifold bolts. I mentioned after that work that i would like to maybe have a deeper exhaust sound. I was told to bring it back the next day and they did an awesome job, and i love the deep rumble i'm getting for my 5.7 hemi now.And while i was there a woman came in for her appointment, but her appointment was for two days earlier. They still took her car in and did the work right then, instead of rescheduling her.Great place and i can't recommend them enough. read more

So, what do you do when you are traveling across the country from Minnesota to New Hampshire and your brakes start to grind, only to get worse with each passing moment? You call the hotel where you are scheduled to stay and ask for a recommendation for a good, fair priced mechanic. And when you end up at Lou's custom exhaust you realize you have hit a homerun!!!!! Great work, fair price and on our way in 4 hours. We are so grateful to Lou and Frank for their 5 star customer service!!!!! read more

My OEM catalytic converter cracked a weld in my old Volvo 240, which can get unbelievably pricey. For $325, they installed a new catalytic converter, put in some new pipe, deleted my resonator, and even fixed some welds that were on their way out elsewhere, and sprayed them for rust prevention. Lou's makes sure to take care of everything you need, not what you don't. I easily saved a few hundred dollars thanks to the fact that they make the exhaust systems in-house. read more

I had an exhaust leak and my service engine light came on... I took my truck to 3 garages in the Seacoast area. On garage quote $2800..00 the another $3500.00. I won't say what the last place quoted me!!! My nephew that is auto body tech in Somersworth said try Lou's in Portsmouth. Great bunch of guy's........ $450.00 all in. Everything I was told needed to be replaced (NOT) Guess I should have gone here 1st.... P.S. in and out read more

Absolutely amazing. I've taken 3 cars here and have been more than happy with how all of them turned out. My first car I went to Lou's custom exhaust in Dover for a muffler delete, where they quoted me over $1000 probably because I was a 16 year old kid. Took it down to Portsmouth and they only charged me $250. The guys there are amazing and have always picked up the phone when I call, even while being super busy all the time read more

The Portsmouth, NH crew are the best. INTEGRITY is very hard to find these days in the automotive world. I've done business with these guys on two separate occasions and they went above and beyond. Others wanted to charge 3 times what they charged me. Complete professionals and top notch quality work that they stand behind. No-brainer. These guys are legit. Jeff Bowden. read more

Went to Lou's to get my exhaust replaced, Frank went above and beyond I was so pleased with the work and customer service I sent my wife's car in for new breaks. Frank exceeded all customer service expectations, he even came in on a Saturday to expedite the work. I would definitely recommend this shop and will 100% come back. read more

This place is awesome!!! My car never sounded so quiet. Thanks for the exhaust work. The guys are all nice and very knowledgeable. I also got a bit of advice on under coatings and a sample spray as I'm from the south and new to the area. They have free WiFi too. Thank you... I hope you got a pizza for lunch!! read more

I have taken my car to Lou's Custom Exhaust on Lafayette Rd in Portsmouth several times in the past few years and have always been extremely happy with the service they provide. I can always get an appointment in a timely manner and I trust that they won't do anything unnecessary. I highly recommend them. read more

The gentleman at Lou's in Portsmouth stayed late, worked quickly and provided services for significantly less than anyone else was quoting me. If you are thinking of going anywhere else for exhaust, brakes or suspension work to your car - think again. This is the place to go no question about it read more

This place has the most skilled people I have seen in the last 40 years every time I have had a exhaust problem they were the most reasonable on price and the work quality is a10 every time !!!!!! Would recommend to anyone who wants a quality job at a reasonable price! Would not go anywhere else! read more

Mike is a great guy and a great dad. I ty iook my car to his shop for some repairs and he took a personal interest in me and my car problem., He watched very carefully as the other mechanic workd on my exhaust then gave me a free Y pipe welding, and brake inspection Highly reoccomended read more

The guys at Lou's were awesome! They were able to get me in and out in no time. If I brought it anyplace else they would have replaced a lot more than what was needed costing me $$$ Great customer support and great price. The place was passed on to from friends at the shipyard. read more
