So I installed direct fit Flowmaster American thunder muffler. Was easy enough. Then I noticed leak at pipe from muffler to one of the pipes leading to tips. Had a shop that installs and sells exhaust, yes very reputable reinstall and torque down clamps. Today I noticed again some leak. Should I weld? Should I back muffler off from from pipe and push in duals further then re torque? Anyone. Have this situation arise? Should I **** can and put stock back on lol. PITA!
