I’m searching for an exhaust system to install on my G20 330i and I have came across several options but I think I am stopping between:

Fi Valvetronic Exhaust System AWE Track/Touring Exhaust Systems

The significant differences I found between them is that Fi can be installed without cutting my OEM and from the videos I watched has a better soundtrack, but it is a lot more expensive than the AWE. The pro of the AWE for me is mostly that it is a lot cheaper but it will require cutting my OEM which is not something I am comfortable doing.

I am asking this to see if you guys can share your opinions on this or if you even have some other suggestions I would be very grateful for them.
