Engine/exhaust noise

[Brasco469]

Hello everyone,
I need alittle help diagnosing an engine/exhaust noise. Car is very loud when accelerating especially when driving next to a wall on the highway. I have been under the car to look for leak in the exhaust but couldnt find any. The manifold has already been replaced by nissan due to a crack but this is a different noise, sounds like im driving a stock 1987 cutlass supreme with the same exhaust noise, lol. Any help will be appreciated.

I have a 2011 Altima 2.5S. I bought mine used from a dealer. It has 14k and change miles and I too hear a ticking. I visited two dealers they said it's and injected/manifold thing. I guess they are made of plastics and "rattle". Is the same thing you hear?

The ticking you are getting is the fuel injectors which is normal, I have more of a exhaust leak, I'll just wait till it gets louder to find the leak.
