135i stock exhaust mod

vrod · 04-29-2010, 01:04 PM

Is there any mods for the stock exhaust to make it louder, i heard of some people unplugging the exhaust valve hose which bmw installs for drive by noise regulations. From what i know the bmw performance exhaust does not have this...is this safe to remove from the stock exhaust? Thanks

Yes, it keeps the car quiet below 3K rpm...Took mine off same day i took delivery.

Good to know, did you unplug the hose circled in red by the exhaust or disconnect the connector located in the trunk? Which method is better?

i put it in a box next to my stock exhaust which is now resting in my garage.

(Correct me if I'm wrong 1Addicts gurus), unplugging the tube and closing it off is known as the "golf tee mod". I plan on doing that this weekend now that I have time. Anything to make that exhaust sound sweeter

I did mine by the exhaust. It does sound significantly different, but it's no where near the tone of an after market exhaust.

Search 'golf tee'

It will remain the same anything over 3K rpm but below you will notice slight diff.
