Slightly tinny exhaust note and ticking noise (360)

Better make sure you are not hearing cracked exhaust manifolds (exhaust leaks go tic tic tic)... If you are, the next sound you could possibly here will be many hundreds/thousands of $$$$'s hitting the service counter...

Get an opinion of noise from someone with expierence with cracked headers..

 

A sign of cracked headers is that the ticking sound is louder when cold than when warmed up or hot. This is because heat expansion tends to seal up leaks. If they are leaking when hot, there is a serious issue. But the only real way to tell, however, is with a smoke test.

As for the sound quality change between low and high RPM, the stock exhausts have valves in them that are normally closed but open at high RPM, so that they're quieter at lower RPM.

 

if it's the lifters which is fairly common I hear you can change to mobile one oil which normally resolves the issue

 

There is only one way to produce a better noise at 50 mph which is to drop it to 3rd gear.

That still gives you some room to play in the RPM band.

 

Let us know what you find- Hopefully nothing major

 

Get it in writing.

 

lol!

 

A crack exhaust manifold or just simple loose headers bolts. I've also noticed that the CAT sits right above the thin heat shield above the CV boot can cause tin like noise too if they are slightly touching.

 

You acted right!!
When you find a suspicious noise in the engine you never act paranoid, it is better be careful than ignorant!

I’m happy that it turns good for you!
