BBR Tuning High Performance F2 Thrust Exhaust Muffler- Black

Sounds great and it look awesome! Perfect fit. And increased a little more power because of better airflow.

I knew this was loud when I got it, but I also saw a lot of people with pretty significant gains. If it's that good, I don't care how loud it is. So I installed it and went for a ride. My top end increased by about 3-5mph and I got better mid range power throughout. I couldn't be happier with the performance. I put a fiberglass pipe wrap over the pipe after I burned my leg. The wrap fixed it. Now, the noise... I figured I could put up with any amount of noise. I like loud pipes. But, after installing this, I was literally embarrassed to drive it through town. I was driving down my block, which is basically in the woods, and my neighbors covered their ears. So I basically removed the pipe and it's sitting on my garage floor. I would install it if I was riding through a more rural area or racing, but I am basically too embarrassed to ride it around my neighborhood.

Will have a technical review after installation and testing but my heart sank when opening the box. First impression is this must be a 3rd grade industrial arts class project then I remember it was from BB. WOW. LOOK at the first 3 pics the bubble gum welds on the F2. LAST pic is the stock muffler came with the engine kit I first purchased notice how clean and smooth the welds are. Like night and day. If you are such a terrible welder perhaps a grinder is a good thing to have handy Update: user eats own words. Yeah welds are still ugly but they hold. Noticeable increase in torque and low range pulling. Very impressed. Also installed boost-bottle same time so I don't know what is doing what at moment waiting brakes then serious test continuation..

I bought a black one for my son's bike and it was way better than I expected! Pretty good fit with some minor tweaks. It's a bit louder than the stock exhaust but makes up for it in the performance gains. Better quality than I expected and a better performance boost also! Love it and am ordering another for my bike.

Is a great exhaust super loud though only complaint is it’s heavy for the engine mounts so u reallt gotta use the extra mounts piece they give you but u gotta make it perfect or it won’t help anything

Fits perfect on my bike, haven't ran it yet, but it looks awesome, unlike the stock exhaust. The design is great. Just what I was looking for. Happy with my purchase!

Low quality welding. Multiple pinhole size leaks throughout said welding. No, it is not worth. Perhaps to "beginners" motorized bike enthusiasts, has some value, but for the "real deal" this is unworthy and should never be mounted on a half decent engine.

This thing added significant power to my bike and is loud. Almost afraid it's too loud, I have a decibel meter and it hits 108 decibals. I think the sound ordanence calls for 95 decibels as the max. I'm just waiting to get pulled over because of it, I have passed several officers on the road and I haven't got pulled over yet. So until I do I'm going to ride it loud and proud. FTP!
