I'm guessing it was a local cop? Call your closest highway patrol post, they'd be able to answer your question. Although, I'd probably leave out the part where you got ticketed so they don't cop an attitude...no pun intended. Just present it as you're considering replacing your mufflers w/ a lower cost alternative, dropping off a box of donuts may also be helpful.
