I have what I swear to be an exhaust leak from the header or where it connects to the cat but the dealer said it's a normal sound. I don't hear it at idle but under light acceleration or deceleration, it sounds like a 20 yr old Ford work van. Anyone have a similar sound that's apparently normal for a 6.2?? I also have a loud lifter ticking/knocking noise. It happens every morning and if I let it sit long enough during the day. Thanks in advance. Here's a video of the lifter noise. https://youtu.be/t9UFIEB1TWI -

Alright, before you say you don’t hear anything let me explain first. This video posted below is my 2021 Trail Boss 3500k miles and has the most annoying exhaust sound. I know there’s some serious pro’s on here who could tell me what’s going on. Essentially any time I start it up high RPM, accelerate, or decrease RPM’s I’m greeted with this annoying metallic rattling noise coming from exhaust. Took it to dealer who claims it’s normal (per-usual) and says it’s the liters I can hear in the exhaust tone. They checked exhaust donuts and heat shields and found no issue. However you can hear a rattle and what sounds like an exhaust leak. Was told it’s a flapper but it’s not, flapper is toward back passenger side. This is front passenger side. I could best describe it as escaping air coming from somewhere near the manifold I’d assume. Almost like a metallic farting exhaust noise for lack of better description. Videos to follow of noise while commuting. -
2011 Silverado, 5.3L 1500 LT. I noticed that the driver side FRONT exhaust bolt is broken off. I can only stick a probe in the hole about 1/4". I assume the head sheared off below the flange. i know this is a common issue, but 99% of the time its the rear bolt. Is there an easy fix? they sell a bracket for the rear bolt breakage, but is there anything for the front? or do I need to bite the bullet and pay a shop to get it out? appreciate any input. thanks
