I have a question regarding full exhaust and quiet cores for the raptor. I ride in the country so there is no problem with noise, however, I go to the dunes 1 or 2 times a year so I need something that can kill the noise level. I'd like a full exhaust and I'd love to get a Sparks but from what I hear they are loud and I don't want it to be so loud I can't ride in the dunes. They don't make a quiet core insert do they? Any help is appreciated.
