BUYER BEWARE!!!
Long review but you need to read it! I got referred to this place by a fellow coworker who had a Flowmaster muffler installed there for a good price. So I stopped into Lou’s. There are two people that work their. One guy that sits at the desk and a young kid welder. I asked what it would cost for a stainless steel Flowmaster super 44 series muffler to be installed in my truck. He said they only carry the 40 series flowmasters and it would be $ 220 installed. So I thought that was cheap for a Flowmaster install so I told him to do it. As he was about to install the muffler I happened to look at it and it didn’t say Flowmaster, but instead 409SS. He said that 409SS is 40 series Flowmaster. I didn’t really think much of it cause I’ve seen Flowmaster muffler charts that show 409S on it. Got the muffler installed and went home. The next day I was getting curious about that 409SS stamped on the muffler and no sign of Flowmaster on it. So I decided to call Flowmaster direct and ask a rep how to distinguish their mufflers. The rep said the muffler should have a stamped «flowmaster» on it or a «made in America» stamp. I double checked my muffler both sides it had neither. Then the rep asked the name of the company and when I told him, he said they are not a licensed Flowmaster supplier. So I then googled «409SS Lou’s custom exhaust» and there it was! That was their own «in store brand» muffler that’s only sold at Lou’s. It’s posted on their website along with flowmasters and magnaflow. I also was able to find other Unilocal reviews from Lou’s customers who were also dooped into thinking they were purchasing a Flowmaster setup and later finding out that in fact they installed their generic mufflers. I was blown away… FRAUD! So I immediately called Lou’s and stated I had a muffler installed their, and asked for a Flowmaster 40 series and paid for one (according to my receipt which states Flowmaster muffler install). But when I look under my truck I see a Lou’s in store muffler? I then stated I couldn’t find the Flowmaster name anywhere on it?
The guy stated we don’t carry flowmasters we have our own.
I then asked why he said he carried Flowmaster and its stated on their website?
He stated they carry mufflers that are similar!
He then stated «they are the same, we get them from the same factory. We just get them before they stamp the Flowmaster name on it. If you put them side by side they look the same.»
I then asked where the Lou’s mufflers are made?
He stated «AFRICA»!
I then said that’s funny cause flowmasters are «MADE IN AMERICA!»
He then started to get agitated that I caught him in a lie. So he stated «so what are you telling me? You want to come back and I’ll put your old exhaust on and give you your money back?»
I then stated «yes»
He stated «fine» and hung up.
I then advised my fellow coworker who originally referred me to this place to look at his muffler. He did, it was the Lou’s in store brand. Not, the Flowmaster he thought he had purchased. He then told the other fellow coworkers who originally told him to go there for flowmasters and they were shocked as well cause they thought they purchased flowmasters.
I ended up going to another muffler shop the the next day and had them install a stamped authentic flowmaster muffler and cut out the Lou’s muffler (I did not want Lou’s to touch my truck again). So I took the Lou’s muffler back to Lou’s for return. When I walked in with the muffler the same guy I spoke to states what’s up? what’s that for? I said «to return». He states «well, I’ve never done a return before so I’ll have to call the owner «I just work here». He then gets on the phone with the owner and then tells me I have to come back tomorrow for my $ 220 because they don’t have it there. I then stated I was not coming back, a business should know how to do a return. The «I just work here guy» said he doesn’t know how to work the credit card machine for returns and there’s not enough cash here. I then told them I’ll just call the police and maybe they work this out. I think then they must of realized I wasn’t leaving without my money. All of a sudden the two guys working there jointly collected up money from each other which totaled $ 220 in cash to give to me for my return.

Excellent service, both times my audi needed repairs the mechanics got straight to the point and fixed what needed to be fixed rather than try to upsell me on un– needed exhaust parts. All work was done with quality at a fair price. will continue to use for all future exhaust needs and would recommend to anyone.

Needed muffler replaced after another place didn’t tighten bolts.
Quick, cheap price. Can’t say more. Except great customer service. Highly recommend!

Family run franchise in Chelmsford. Really nice, informative guys. They replaced the pipes and hangers that were needed after showing me where rust has taken its toll. Walked out 40 minutes after arriving without an appointment. Best of all, it was much cheaper than I expected. The other hack shops would have replaced the whole system. A+ for honesty and excellent service.

Very friendly and professional people. They make sure to go out of their way to ensure you understand everything and are patient with your questions. The vibe from this shop is they’re not there to just sell you something and take your money. They make sure you’re happy with what you want done, first and foremost.
I had a simple exhaust modification where the stock mufflers were cut out to be replaced with tips and the central resonator replaced with a dual in/​out free flow muffler. I brought my own parts which they gladly used. This wasn’t the best choice and I wasn’t happy with it, so I called back and they had me back in a couple days later no questions asked. This time I used their parts and the quality rivals the more popular aftermarket suppliers.
Overall their work was very good. Welds are solid and have held up very nicely. They welded hangers to the piping and bolted on hooks to factory locations. There was no drilling or welding to the frame (they only do that unless absolutely necessary). They double checked all their welds with a stethoscope and welded shut any leaks.
Definitely recommended.
