Exhaust smell

[Jac2707]

I have recently put a exhaust on my mk6 fiesta and I’ve noticed a smell when I floor it, it’s not like a burning smell but reminds me of being at a track day, just wondering if there’s anyway to fix this or if there’s a problem starting to form

Have you leak tested the exhaust since you installed it?

I have the same issue but I know iv got a leak 3/4 down the system so I imagine you've got a leak somewhere as mentioned above
