Big City Thunder QQ Monster Baffle

$68.00

Product Description

Price includes free shipping in the USA

QQ Thunder Monster Baffles: Looking for the performance that a motorcycle baffle can give you but want to tone it down a bit with an even deeper exhaust note?

These baffles work in our 1330 performnce pipe and have had great reviews from early adopters.

Here's a recent review:
"I recently installed the Cat  performance replacement pipe, there was a big difference throttle response as well as sound but there seemed to run a little flat. After reading some of the forums and what others had to say about your pipe I checked out a company called Big City Thunder who offered a baffle that would put back some of the back pressure that was lost when the cat was removed. With Big City's Thunder baffle installed the bike ran smooth and quick. Throttle response was impressive.

The Lamonster pipe was flawless and installed without a hitch. I would suggest you check out Big City Thunder and offer it along with the pipe."

  1. Nice deep sound 5 Star Review

    Adds a new dimension the the Straight Pipe muffler bypass,
    perfect sound.

  2. Spyder F3S with 2 Brothers pipe 4 Star Review

    Posted by on May 11th 2017

    I installed a 2 Brothers pipe on my 15' F3 Spyder, with the PX1 insert. Sounded great and run well on the top rpm range but midrange was almost gone. Ordered the Big City baffle should by Lamonster and the problem was solved. I attached it to the PX1 baffle, and since it was just made of cheap magnesium type metal it broke and the Big City baffle was just floating around inside my pipe. So, fortunately a own a lathe and I made a nice steel insert like the Px1, attached the Big City Thunder baffle to it and she runs like a house on FIRE! I even trimmed a little of the Big City baffle off, sort of tuning the engine, and I now have great throttle response, midrange and top end. The Spyder pulls from bottom to top without a and flat spots. Love it!

  3. Great product to use with Lamonster performance pipe 5 Star Review

    Posted by on Mar 11th 2017

    I installed the performance pipe an did not like the poping noise when you slow down and when you crank the bike. After installing BCT baffle the problem was solved. i recommend the pipe and baffle to be used together. Both products are very easy to install.

  4. Perfect 5 Star Review

    Bought this to go along with Lamonster's cat delete pipe. Could not be happier. This gives the bike that perfect sound between louder than stock and not obnoxiously loud.

  5. Must have with 1330 pipe 5 Star Review

    Posted by on Feb 2nd 2017

    Installed this baffle to make up for back pressure lost removing the cat. This combo, 1330 pipe & baffle gave my 2017 Spyder F-3 a significant weight loss and much greater low & mid range performance.

  6. Tone down 4 Star Review

    Posted by on Jan 14th 2017

    Easy install and it done what I needed toned down the tinny sound from the muffler replacement pipe and the stock muffler,
    Better sound!

  7. BCB QQ 5 Star Review

    Posted by on Oct 26th 2016

    I installer it in the Lamonster muffler replacement pipe. It
    was installed in the front portion of the pipe with the cone
    facing away from the engine. I don't know if it sound any different because installed from the start.

  8. Great Product 5 Star Review

    Posted by on Sep 14th 2016

    Pleasantly surprised...easy installation except for removing those damned springs...lol...drill one 1/4" hole for set screw and all done... BTW, the springs install much easier...fit was perfect for my cat replacement pipe (not Lemonster, sorry)...the baffle cut down on the loud popping when starting but still has that throaty growl we all love...feels like there is more midrange torque...I'm very happy!

  9. MIDRANGE TORQUE BABY !! 5 Star Review

    Posted by on May 16th 2016

    I saw some write on SL on this baffle and next thing I saw it in Lamonster garage store.So, to under stand the function of the baffle I called BIG CITY THUNDER and spoke to the owner over the phone about this baffle. He said more midrange torque and better sound. He was correct.
    I installed this baffle inside of the performance muffler replacement pipe and have replaced the stock RT muffler with the BRP Akripovic pipe. Awesome combination not only great sound but lots of midrange torque. Using this combination has awoken the inner beast of the 1330 motor.
    This product like all other products sold by Lamonster Garage is top notch with fit and finish being show quality.

  10. Uodate update 5 Star Review

    Posted by on May 15th 2016

    Forgot to say the mid-range torque is back. Can't wait until I take the bike out to the strip for test and tune night!
