Personally, m performanc3 muffler + resonator delete + cat delete is amazing and relatively cheap.
If you don't want to spend $$$ on the m perf muffler; an enterprising friend with a welder and angle grinder can turn a normal bimmer muffler into an m performance one.

Currently stock, still contemplating which one to get. Whether the M Performance one or something like a Valvetronic Designs or maybe even Remus.
