The Kit
I ordered a SuperSprint exhaust from Performance Automotive. They have a choice between round and square. Since I had seen the square on Brad Otoupalik's E39, I was hooked. You can also see and hear it on his business webpage: Evosport.com.
Old vs New
The kit before mounting and a comparison of the old and new exhaust systems. The weight difference is huge, but the most important thing to me was the look and the sound. And boy, does it sound GOOD.
Center Resonator Out
The center resonator removed and the 3" pipe to the cats. All you have to do is order two 45 degree 3" mandrel bends and any muffler shop can mount the pipe for you.
Measuring the Bend
Measuring to make sure the bend will fit well. The bend is really simple, and I was overcharged for the work. I suspect the price had a lot more to do with the car than with the work itself.
Test Fit & Level Check
Is it level? A little obsessive compulsion is a good thing. Too much, and you'll put a level on your exhaust. The funniest comment so far was from a colleague who asked, "Now, was the GROUND level?" I about died.
The Finished Product
I love the sound, especially at full throttle. It's been a while since I drove an E39 without the SuperSprint, but I remember thinking it was smoother getting to the upper RPMs. There was a little bog on the way up before; now it just silks right on up there.
