I'm impressed with the speed that response got posted.It is healthier to not do mods, especially the damper.
Honestly I have had both, reliability wise it’s a nonstarter. Gives you less back pressure so free flowing. Just my opinion but I think you get a very slight performance boost. Now to quantify that opinion, only a dyno test will tell for sure. They do sound better though!Question is, can it hurt the reliability of an engine, or can it help?
As hard as it is to resist, my opinion is to hold off on anything that could cause a Ford shop to void my warranty until after my warranty has expired. Nothing wrong with anyone who would disagree, but if something happens and there's a question on whether or not the piece caused or contributed to an acceleration of failure, I don't want to be going against Ford's pricey corporate lawyers.Question is, can it hurt the reliability of an engine, or can it help?
Any muffler of good quality will be as reliable if not more so than the OEM muffler. Especially since the stock muffler has a baffle plate restrictor in it that could present flow issues if it were to get clogged up with soot. The best option then would be to get a stainless steel muffler as it'll never rust, but any aluminized or galvanized muffler will be fine.I don't care about the sound. I care about the reliability.
If that's your mission I say just stick with the OEM exhaust. Ford tests every system for reliability before the they sell their vehicles, so I'm good with the stock system.I don't care about the sound. I care about the reliability.
