Just noticed that one of my exhausts makes a tshhhhst sound when I let off the gas. I've only tested on idle as you can't tell when driving. I build some revs and let go and between like 1500-1000 it makes the noise. Deffo not from the engine bay. It's got full decats fitted etc.

Just noticed that one of my exhausts makes a tshhhhst sound when I let off the gas. I've only tested on idle as you can't tell when driving. I build some revs and let go and between like 1500-1000 it makes the noise. Deffo not from the engine bay. It's got full decats fitted etc.
Any ideas?
