Who to contact for E90 335 exhaust upgrade?

[callumb 3]

Hi,

I'm looking for recommendations on who to contact re upgrading the exhaust on my 09 335i sedan.

I've been looking for a while and there's not a lot that comes up when googling that doesn't seem overly expensive eg. SuperSprint / Borla being 3-5k.

I've read about the mod that can be done to existing mufflers which isn't really my thing.

Who are the go to people for this kind of thing? I'm in AKL.

Cheers

Not much to achieve with this exhaust, power wise, cat removal from down pipes appears to be the main restriction, but only really if tuned.

Very easy to get a loud, droney car if you start cutting/ deleting mufflers etc.

Aftermarket products are costly and at 10-15 hp at most.
