  1. Mitch Saunders

    I bought the the 63mm torpedo and fit it myself on my CB750 and the sound it makes is incredible ! Heard a few before and afters on you tube of others using these and there unreal !

  2. Adrian Korner

    I have now installed both the 43mm and 53mm mufflers onto a range of bikes (from 250cc-1300cc) and have been very happy with the quality and the sounds that it brings to the bike. The packing works well to produce a deep, loud and refined sounds as opposed to cheaper copies that result in an unbearable tiny noise. These mufflers are worth every penny!

  3. Jeremy Williams

    I’ve fitted a 53mm torpedo to my Xsr700 on aftermarket headers. It was a touch to loud. after speaking to Tom he sent me another baffle and it’s pretty much spot on now. Sounds and looks amazing!

  4. Adam Carson

    i bought a 53mm for my 83 GSX 550 after being happy with the electrics gear I previously got from PBM. It looks solid and clean and has a great little angry note to it. Still haven’t had trouble from our mates in blue even without the baffle in.

  5. Nathaniel Cardoso

    I bought this for a cbr cafe racer project I was working on. It is by far the best sounding exhaust I’ve ever had puts a smile on my face every time it starts. The workmanship is perfect top notch quality. I will be back for more

  6. Alastair Langridge

    This muffler is so good, put the 43mm on my GN250 to replace a cheap eBay one the previous owner put on. The bike now sounds amazing now, the volume is loud but the sound is so clean and full, love it. Highly recommended! Thanks Tom!

  7. Paul Woods

    Just fitted out second PBM Torpedo (Previous was to a Mercury 250) to a Royal Enfield Continental GT535.
    As before the quality is excellent, but the sound is fantastic! On this bike the dab Killer is definitely a must, but the bike idles beautifully, has a really nice deep note in acceleration, & a wicked crackle & pop on the overrun.
    Will be sending through pics & videos soon.
    Cheers Yom, once again.

    Fitted the PBM Torpedos to my BMW R80, I used 38mm version. They fitted beautifully, straight on to the exhaust headers.

    Quality is fantastic and the sound is amazing. Deep and raspy.

    I searched for mufflers for some time, seeing all the usual cafe racer suspects. I just felt these were a notch above.

    The help from PBM is always friendly, even with my simplistic questions.

    Video shows mufflers (DB killer not fitted).

    Thanks Tom!
