    Sounds awesome
    If you want people to hear you coming this is definitely the pipe for you. Sounds and looks great. I didn't even have to rejet my carb. This pipe is a very good investment over the stock pipe on my 400x.

    Perfect fit great soond
    It is very loud so if you have annoying neighbors that will complain don’t choose this product. Or if you want to make them annoyed enough to move out then choose this. Very deep sound and no tuning needed took around 15 minutes to instal

    HMF fits and sounds awesome
    This pipe fit perfect out of the box with no needed modifications. Used a little red loctite on the bolt. Sounds great and with the re jet I noticed a good power increase.

    Awesome pipe
    I installed this on my 2008 Yamaha yfz450 and also dropped the front sprocket down one tooth and installed a k&n air filter and ith now has amazing power well worth the money.

    Great Exhaust
    I just ordered this exhaust for my kfx450r, it was at my door in 3 days, and took me about 10 minutes to install, super easy. Instantly after installing this pipe, I noticed the gain in bottom end power, it is definitely more snappy. I would recommend this exhaust to anyone. Keep in mind though, it is super loud.

    Good but very loud!
    This is a great product. I have always been a fan of hmf. It was easy to put on and sounded great after. It gave it better power but it was very loud! Do not buy if you are worried about noise complaints!

    good
    this pipe is amazing when you get it to work, you need to tune your bike to the pipe witch is a pain if you do not know how to tune a bike but if tuned properly it adds loads of power i love this pipe and it sounds great...the only thing is it mounts up a little funny but its not too bad...totaly worth it!!!

    Nice pipe for the price
    This pipe is made much better than the FMF pipe that I through in the recycle bin, I didn't even half to remove the spark arrestor it came with because it comes loose in the bag of parts. Fits well and was easy to install once I got the OEM gasket sleeve off which was not much fun, had to take the entire header off and take over to the vice to remove. Looks great and sounds even better, performance was the same as the after market pipe I took off but still much better than the OEM pipe.

    2013 yfz450r great deal
    installing was very tight to say the least and I could only use the back mounting bolt but once installed and bolted down sounds great. Tuned with a lexx tuner major power and performance gains. I gave this pipe a top rating due to quality construction and a good clean look I highly recommend this for a slip on.

    Very curious if this hmf slip on would go with the fmf mega bomb stainless steel header? Please let me know asap
    Jeremy Wade K on Mar 4, 2017
    BEST ANSWER: I couldn't tell you if it'll fit but, if it does, you're gonna be stoked. This exhaust does not disappoint, makes me smile everytime. This IS the bomb.
    Will i need the fuel-injection controller for a stock 2014 Z400? Im not looking for maximum performance. I just dont want to damage anything or void warranties.
    Leah M on May 2, 2017
    BEST ANSWER: I do know HMF highly recommends their fuel injection controller for any installation of slip on or full system exhausts, it is pricey and i didn't purchase it because everyone I asked said slip ons don't need tuning. My 2016 raptor 700 still runs fine and I feel that slight snap of power with the exhaust. Sounds great too.
