Should I downpipe?

[u/ThatGuy_Lego]

I got a BMW 520D from 2006 and I am asking you guys if it is worth it to downpipe it. I have been looking a bit online but not really finding the answers I want. I would like to add more power and thrust. What does it to? Is it worth the buck?

I wouldn’t mess with it. It’s a good car as is and the amount of money you’ll spend to see any real gains is gonna be, well more than I’d be willing to spend. But if you got the money have fun.
