Big City Thunder QQ Monster Baffle

Out of Stock


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. 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!!!!

  2. 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.

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

    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.

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

    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.

    Wasn't sure that this would do much good but thought what the heck if all it does is tone down the noise a bit I'll give it a shot. It sounds great with the stock muffler and cat bypass and does help with low and mid range power. A real winner.

    A little early to tell since I just got it in but I like the sound - Deeper etc. Not sure what effect it may have on performance. Good I hope. Certainly worth the $68

    Simple install in Lamont's Performance Muffler. Combo, BCT baffle w/ PM, makes for an awesome sounding F3. Low rumble, not so loud to be obnoxious or drown out the tunes.
