as the title suggests. Just bought a 172 and noticed it was quite loud on low revs and found air pissing out of the welds on a silencer. When starting from cold the idle does seem a bit lumpy would a hole in the exhaust cause this due to low back pressure?

I have a missing backbox sized hole in my exhaust at the moment. It's bloody loud, but isn't any rougher than when it was on!
New exhaust going on this week!

My backbox fell off last week, the noise it made was ridiculous! Fun at first, but leaves you with a headache. And almost everyone you drive past down the street looks at you with hate in their eyes lol. Quite glad its sorted now! But I noticed no difference to the way the car ran. I expect a pre-cat blow would make a difference, but not so much post-cat.

You may need a new mid-rear clamp aswell, I'd check to see how corroded your existing one is.

When I lost my backbox my 172 felt gutless.

I haven't really tried booting it, anything above 3k and my change in the ashtray rattles like crazy, along with everything else,
Pretty sure every bolt, wherever it may be, is going to works itself loose!
