135i turbo exhaust...golf tee?

hello,

i seached the forums for "Golf tee" but couldnt find anything on this mod...

my old man just bght a new 135i australian spec with 6sp manual. ive been reading some cars come with a vacuum operated valve that closes 1 tail pipe at low rpm or when cold. apparently there is a vacuum hose somewhere you can jam up with a golf tee or similar and keep this flap open for more noise...

anyone know what im talking about? can it be done? anyone know a link to a DIY site etc?

thanks and sorry if this has been asked for before, i did do a search of this forum first and anyways im just a simple e36 driver .....

tks

If you want that 1er to be loud the ghetto way just lift the car and unbolt the exhaust right in the middle. Its just two bolts. Try and tell me what you think.

Hello, please look at your exhaust and see if there is a valve/flap in one of the tips, if there is there is a vacuum hose connected above it. Disconnect it and put a gold tee in there and zip tie it. Enjoy

My 335i had the exhaust flap and valve, not sure about the 135i.

But if it does, I would advise you to use something else than a golf tee to stuff the vacuum tube - I've done it like that the first time and over time it got stuck, it was a pain to remove. Use an 8mm or 10mm stainless steel machine screw to plug the line - when you'll want to remove it, you simply unscrew it. Dead easy.

Also use a zip tie to secure the vacuum tube out of the way and perhaps a little rubber cap on the valve vacuum nipple (so dirt/rain doesn't get in). Any automotive store will carry those little rubber caps, they are used to plug vacuum lines, brake lines etc.

adc - the 135i does use the same flap and valve. Your advice is right on. I initially used a golf tee and then removed it when I noticed a bit more drone than I was willing to put up with.

Good to know!

Droning could also be dependent on your SW version. When my 335i had the original software (V.27) or the latest (v.32), droning was not a big issue. But while it ran on BMW's infamous V.29 software, I was also tempted to undo my golf tee mod...
