Flexible Muffler 🔧 Engine by Niome Viper Review

I like the sound but after three months the built-in bracket that connects to the exhaust broke leaving a hole in the exhaust. I used a piece of metal and a weld to patch the hole and had to find another way to hold the exhaust pipe.

I love this exhaust. It works really well, love the flexibility it offers so you can convert it to where it's going to work and it's very easy to install. It took me 20 minutes because I wanted it. The muffler on the end keeps the noise really good and also stays cooler than regular exhausts, even the best exhausts I know. Overall I am very very satisfied

WARNING WARNING. If you have an oval shaped exhaust port better plan to reshape the muffler pipe end where they join or my neat mine got started from overheating and I couldn't otherwise stop it and then tighten the boot backwards. Carburettor it's a good thing I had the filter removed when I almost lost my engine and I also found that the flex pipe was under the flange which traps the heat so unless you plan on a little reshape and trim, pull out flex pipe, take out and connect, so that the…

I was very surprised that it was easy to install. It took me five minutes to remove and install this expansion chamber with spark arrester. The exhaust flange is the best I've seen so far. It has a much stronger mounting flange with a reinforcement weld to prevent warping from over tightening causing exhaust leaks. After this was bolted on, I lowered the exhaust pipe and mounted a muffler on the rear frame under the engine, which is very flexible and can be easily adjusted with various mounting

Rating updated. Someone cut off the flexible hose and just attached the muffler to the exhaust adapter with bolts and high temp welding. And it has a stainless steel packaging. I want to weld it but I don't have a welder. No more loss of power on my 49cc petrol scooter now that it doesn't have that flexible hose anymore. In fact, the climbing performance is slightly better than the stock muffler and stainless steel muffler. When I first tested the muffler, my 49cc engine was slower and louder…
