hansvonaxion Posted May 7, 2011 Share Posted May 7, 2011 When I was trying to swap the exhaust on my second gen GT-B (JDM) I noticed there was something connected to the pipe just before the muffler. I wasn't expecting it because there's nowhere for anything to connect to the replacement. Edit: Found out what it is, quote below. Link to comment Share on other sites More sharing options...
hansvonaxion Posted May 8, 2011 Author Share Posted May 8, 2011 OK so I got the exhaust out and there is a valve on one of the pipes leading into the muffler. I've just hooked and bent the cable under the bumper at the moment. Here's a pic... http://img.photobucket.com/albums/v291/hansvonaxion/Legacy/exhaustvalve.jpg Edit: Found this on Wiki page for the gen 3... An electronically controlled rear muffler is used to keep the B4 quiet at low road speeds. The pipe that leads into the rear muffler is divided in two, with one pipe equipped with a flapper valve. The ECU - working with an actuator and cable - opens this valve when travelling at medium-to-high road speeds. This increases exhaust gas flow. Guess it's on the gen 2 also. Should I just leave it as is? Maybe disconnect the actuator? Link to comment Share on other sites More sharing options...

hansvonaxion Posted May 10, 2011 Author Share Posted May 10, 2011 It was pretty surprising finding it, more at home these days on Astons. That could be a cheap DIY mod, fix the valve permanently open... wish I'd done it before swapping the muffler to see the affect - the stock pipe is pretty big. If I end up having the put the stock back on for the Shaken (unlikely) I'll open it up then and post the results. Link to comment Share on other sites More sharing options...
BAC5.2 Posted May 10, 2011 Share Posted May 10, 2011 I never knew the twin turbo cars had this!
