COVID-19 UPDATE: Starting March 30th we will begin shipping orders once a week for IN STOCK items only. We have set up an automated phone service that will allow you to speak with a sales representative during this time, if needed. We thank all of our customers for working with us during this time and look forward to returning to full production in the coming weeks.
Turn your Screamin' Eagle II mufflers into a completely new exhaust system in minutes and have a deeper, throatier hot rod tone to the exhaust note with our easy to install Thunder Monster replacement baffles. Slide out the old, slide in the new, no cutting, welding drilling or hassles. It's that easy.
On the other hand if you want to tone down the volume, deepen the note and improve the performance of your Screamin' Eagle II mufflers? We have the answer with our new QQ Series Thunder Monster baffles that install in the exit end of the head pipe and are run in concert with your present Screamin' Eagle II baffles.
**Orders usually ship the same day if placed by 11am ET M-F.**
