How much does the stock muffler weigh?
 

I know there is a thread somewhere, where all the weights of the stock and aftermarket exhaust parts are listed, but I can't find it anywhere (why isn't it stickied?)

You've obviously done 0 research.

Believe me I did and when searching for weight in this sub-forum you can imagine how many fu**in' results you get.

Thanks for the link, but actually this is not the thread I was looking for. A few months ago i stumbled upon a thread where all the aftermarket exhaust parts were listed with their respective weights. (this thread should be pinned)

boom
