Lovely burble!

Alext · 10-14-2008, 11:12 PM

Travelling with the windows down I have just noticed a lovely burble from the standard exhaust on decelleration. Very happy with the stock exhaust. Not too loud to overpower the wonderful sounds the engine makes. It is just another great suprise I had not expected from my 135i!

i like the note of the stock exhaust, just wish it was louder. that burble is pretty sweet though.

I was just noticing this yesterday. Winding it up in 1st and 2nd gear sounds so sweet with the windows down.

I wish there was a way to make the stock exhaust just a little louder, it's just too quiet

Golf tee?

imported_mega · 10-17-2008, 02:24 PM

golf tee (or zip tie it's easier) there's a vacuum line that closes one of the exhaust openings in the muffler

just pinch the line or plug it, and it'll stay open, it's a noticeable difference at idle
