Fantastic sound for my money!
I really can’t say enough good about this muffler. First, for me the sound was perfect. I bought the dual inlet dual outlet polished in 2.5” for my 2012 Tundra 5.7. I had a professional install it as it something your going to have to modify your existing exhaust for. My shop only charged me $300 and did an awesome job with some 10” x 3.5” tips thrown in. This guy installs a lot of the “leading brand” of mufflers and he said it sounded a lot the same to him. It has a deep, throaty rumble that sounds like a truck should and very minimal drone in my truck. In fact, I have to listen pretty hard to hear it at about 1,700 rpms. I can see if you were towing, it might be more noticeable. At this price point, you cannot beat it. The leading chambered brand would’ve cost me over $100 just for the muffler. Even my installer, who was skeptical at first when I told him about the muffler, thought the build quality was really good. He said it was made a little differently, but it sounds incredible. It your wanting loud though, better go with the single chamber option.

Cheap upgrade in sound and quality part
I put this on my 2008 Jeep Commander to replace the stock muffler with the hopes my 4.7 V8 would sound a little better. The price is great and I'm pleased with the quality. The sound on the Jeep is great. Not too loud at highway cruising but has a nice rumble and is slightly louder. My only negative was my own fault and I messed up inner and outer pipe dimensions so I had to weld the pipes end to end like an amateur so pay attention to that and it should slide over your pipes to clamp or weld. I would buy again and wouldn't spend twice as much on another brand.

It’s a good muffler for the money
Installed on a jeep Cherokee with a 4.0 liter. It’s very quiet (at least compared to the cherry bomb and turn down that it previously had). For the money it’s a good muffler and seems decently made. The paint they used immediately began burning off so it will need a coat of bbq paint to keep from rotting away but otherwise seems great!I personally recommend welding for installation, as that’s what I did.

Price point is great
Great product. They have a good crisp sound. But the package were not the best arrived with several scratches. But nothing that compromised the mufflers proformance

The metal is quick thick and robust, and it sounds great!
This muffler is an awesome value, it has a great tone, not too loud, but has a sporty presence. The material is thick, seems like it will hold up for a very long time.

409 stainless steel.
It's a good product. I've been a professional mechanic for over 10 years at dealerships. I've seen crappy products and good products. And you do pay for what you get, except in this case. You get a very very good product for a budget price. By far the best bang for your buck. I bought this muffler to go on a industrial wood chipper that has a turbocharged 4 cylinder diesel engine. I tig welded to directly to a mild steel pipe with the proper filler wire. This unit welded just as 409 stainless should weld. And the inlet and outlet are thick enough you don't have to worry about burning through. The only thing I dislike about this product and I'm not complaining, I knew it was going to happen. Is that after about 60 hours of engine run time with exhaust temperatures reaching 1200 degrees is the muffler has a very faint purple tint around the inlet. But I nothing less than expected that. I'm a master ASE and EVT technician and I'd recommend this product to anyone for any application. The application I'm using it in can be considered sever duty and its holding up much better than expected.
