HELP...OEM Exhaust Upgrades?

bame_E92 · 03-10-2010, 06:43 PM

Does anyone know the best way to up the noise on the 2009 E92 OEM exhaust? I want to keep the stock exhaust so I'm just looking for something to add that extra roar. I heard of some kind of valve that can be installed but I'm not sure exactly what it's called. Any suggestions?

That valve is on the 335i..not the M3... that's all I know. Not sure how the stock exhaust can be made louder...

There's the Golf tee mod for the 335i which keeps the exhaust flap open at all times. Not sure about the m3 though...

I think he is talking about the guy that put a blast gate in his muffler and took the insulation out.

You could change out the air filter to an aftermarket one and that will make it breath a little better. I don't know how many miles you have but mine seems a bit louder lately. I am at 8500 and it just warmed up here in New England. It is nice to be able to have the window down and hear the engine rev when I hit the gas.

I am seriously itching to put a Vanguard Ti on very soon.

It's called an exhaust cut out valve...

Tune will sort that. Any HFC or Cat delete will throw a CEL
Fab speed uses 200 cel HFC that would prolong the CEL more than say Akrapovic which has 100 cel HFCs
