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. 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.

  2. 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!

  3. BCB QQ 5 Star Review

    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.

  4. 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!

  5. 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.

  6. 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!

  7. Update! 5 Star Review

    Posted by on May 15th 2016

    OK, I have had the opportunity to actually test this baffle in the exhaust system I described in my earlier review. The sound is much deeper than before but still is audible enough to keep that little old lady in the lane next to you away. There is a smooth throaty sound exactly as I had hoped for. It's very loud but now I can start the bike in my garage without pain, lol! PERFECT!!!!

  8. Can't wait to test this! 5 Star Review

    Posted by on Apr 20th 2016

    I had already fabricated a bypass tube and bracket to fit the VooDoo dual muffler (VESPYK8B). Fits the 08-12 GS/RS Spyders. It was too loud to start it up in the garage. The Big City Thunder Monster Baffle did the job on the sound. The tone is lower and it doesn't hurt the ears when started in the garage, lol! Can't wait for it to stop raining so I can give it a good road test to see if the slight loss of mid range torque comes back. I will update this review with the results.

  9. Look at photo BEFORE U Install. 5 Star Review

    Posted by on Mar 21st 2016

    I see the I installed the baffle on the wrong end of the replacement pipe! I think I will try it "my way" for awhile as the springs gave me a challenge.

  10. Simple device that is easy to install. Works well. 5 Star Review

    Posted by on Feb 29th 2016

    Baffle was easy to install. I installed it just inside bypass tube where muffler connects. Took all of 15 minutes to do. Brings back the mid range torque that was lost with the cat bypass tube. Also deepens the tone a bit, much easier in the ears for long rides.
