I installed a Borla S-Type exhaust system on my Raptor when it had 10k miles, fast forward 5 yr and it now has 150k. I installed the exhaust in my driveway by myself, not to difficult of a task. Never could get the tips adjusted to my liking and most of the connections drip water (exhaust leak) so I decided to do something about it. When I parked the truck for the night I crawled under it and sprayed the joints down with PB Blaster. Next morning same thing sprayed everything down with PB Blaster again. After about an hour I crawled under and loosened all the clamps from the resonator back. Once everything was loose I started inspecting the system for missing parts or damage and to my surprise there was none. I made adjustments retightened everything back up this time getting the exhaust tips right on the money. It took three heat cycles using remote start for 10 minutes each time to get all the clamps tight enough so water does not drip from them. Now that all the little exhaust leaks are fixed the exhaust sounds better than ever and what little drone there was is gone. I swear it sounds like an all new exhaust system.
