Just how BAD can installing a baffle in your slip on exhaust REALLY be?!

We've covered the performance affects of exhaust baffles for other engine designs and applications previously in older videos, but we've never shared just how BADLY they can impact a high performance inline-4 motorcycle engine. Whenever you're performing any intake and/or exhaust modifications to your motorcycle, you should ALWAYS consult a professional tuner for input on your build ideas AND talk about how to properly tune your bike for those specific changes. If you'd like us to flash your ECU and/or tune your bike and you have questions, don't hesitate to email us at [email protected]! Our Mail-In ECU Flashing Service can be purchased for supported models on our website 2WDW.com.
