I have jackpot mufflers on a 07SG. I want to replace the tuned baffles with the competition baffles. Any tips on removing them? After removing the bottom bolt..I have tried heating them, loosening with a screw driver, pulling with pliers wit no luck. Any ideas? Thanks, Tom

 

Could try a slide hammer the kind they use for pulling dents, could get one cheap at harbor freight or might be able to rent one. Or take off the muffler and use a crow bar and hammer and pound it out.

 

I recommend removing the mufflers and driving them out from the inlet side, you can use section of pipe or a large socket

 

Thanks for the info....mufflers are off...now the fun part starts!
