I installed my FRPP V6 muffler yesterday and I went to check on all the bolts and check for any exhaust leaks today and I found one around the muffler/overaxle seal. its ever so slight and very little should I worry about that? Should I take it to a muffler shop or ford to fix? It makes me wonder if it could ever be sealed completly with just a clamp, the over axle pipe is all the way in to the muffler assembly(the nipple on the overaxle pipe is sitting firmly against the cut out on the muffler assembly pipe). What should I do?
