FMF Powerbomb header with factory muffler - 05 CRF 450

Did you need to do any rejetting or any adjusting to the carb at all with that new header on there? I have the exactttt same bike same year and my stock header has a crack in it check my video u will see it but i ordered the megabomb header but no muffler was hoping i could still use the stock muffler. let me know thanks and sick bike

@SkinnySkinch hey man my header had a crack in it too! no need for any jetting or adjusting, its strictly bolt on :) the header should be fine with the stock muffler, im not 100% sure since you're getting the megabomb, but i can't see why it wouldn't work with the factory fmf muffler. you should notice smoother power and a way nicer sound :)
