As of now I am running headers and a muffler delete (with resonators still in place) and I have to say I absolutely love the sound. Especially at high RPMs, it freakin screams. Not to mention how much quicker the car revs and how much harder it pulls in the upper range. The one thing I don’t like so much is how the car is loud, ALL THE TIME. In an attempt to keep the noise down I hooked the vacuum baffle in the tailpipe back up and it did help some. I’m thinking of picking up another vacuum baffle from the BMW junkyard (Al Rudd auto parts) and installing it. Possibly moving both valves farther forward in the exhaust. :hmm: I’m not entirely sure if it’s even practical to do. It would be pretty awesome if the valves increased back pressure enough to get that low end torque and open up at 3,000 rpm so you still get that wicked top end. Before I even attempt this, has as anyone else messed around with VO exhaust or electric cutouts on their E46?
