I inspected my Exhaust after listening to it ticking for about a week now, and I noticed that my Air Injection Tubes look a bit rusty. How tough is it to install new Tubes?

Also, is there a chance that my Exaust Gaskets need to be replaced as well?


Thanks

 

probably need new gakets, and you could put new lines on while the manifolds are off, should be easy, but I only took my AIR off
