Hey guys, so soon im going to be driving a 1997 BMW 328i after getting the car and replacing the steering wheel and the ignition and things that where missing in the car.
I have noticed something about the muffler, I turned the car on and only one side of the muffler is working I looked in the other pipe of the muffler and it is closed by a leaver kinda thing and I was wonder what is that for? will it open when the car is gunned hard? or going at a faster speed? thanks
Welcome to the Werkz. Not sure about your particular case, but some lower capacity cars have dual tail pipes for show, but only one of them is open.
umm but its like a leaver like it can open or some sort i took a look under the car and the muffler is aall the way threw from the engine to the back there are dual pipes? they wont put 2 pipes and let one run would they? the engine in the car is a 2.8L 24 Valve ill take a closer look tomm and post pics
The E36 328s have a dual stage exhaust, with one short pipe and one long pipe inside the muffler. The short pipe is held closed by vacuum at idle and low RPM for a quiet idle, but opens at higher RPMs for better exhaust flow and performance. Some people modify their exhausts via the Golf Tee Mod and claim an extra ~1 rwhp from the mod and a more throaty sound at idle.
