kjelders...no issues, just remove two bolts...transfer the little black cover or tips from the stock to the aftermarket...hold your mouth just right and they will slide right on... you can tweak the bits that slide into the cover if you can't get them in on the second or third try...

I have two sets of cobra pipes and they both put out only 102 decibels .... did not have tool to check stock....if anyone has a I Phone you can down load a app and check and report to the board ? They are not loud !!!
