Ah-hem... Can we focus here.
I just got home, driving since 8am and it's 8pm the next day. The car and I made it home fine. More on the trip/results after a long sleep.

I know, when the cat's away.
So here's what I need to do before running on the dyno: Figure out the distance from the exhaust port(last one on the rear, each side) to the o2 sensor for the precat location on a 4.6is engine. Add a bung, a 90° adapter for the sensor and a spacer to keep the tip of the sensor out of the direct flow of the gasses. Install all that. If you know tge length, I'd be super appreciative. Remove my rear cats and code them out completely. Then I can take the car to Dima, DUDMD and get to the numbers you and I want to see. There's still the matter of the lost power last time I was on the dyno... Tune up time? New coils, injectors, plugs, filters...? On the initial feel/sound from the headers: Driving 1,800 miles from La Jolla, CA I can say they add to the aggressive tambour of the exhaust. I was more nervous than ever passing cops. Average driving, each shift sounds like I'm trying to race. In other wirds, before it was just a rolling build up to peak volume, now it's just evil from the get-go. Fifth gear pulls harder, fourth is fun but 3rd is my new best friend. The headers sound so perfect. Keep in mind, the only "mufflers" I have are the m5 rrsonator and the post cats. So getting on it is almost as loud as these pipes can get. There's a slight vibration at idle like a 12 or 15" subwoofer is blasting @ 25 htz. Before, the exhaust manifold was absorbing the offset explosions within one single piece. Now, each explosion has its own escape route and so there's nothing to lessen the energy transfer to the engine, the engine mounts, frame and car as a whole. I might add a washer (rubber) to the engine mounts to dampen this. I also have a little while before all the tubing has settled into place and found their comfortable homes. Once a week goes by, I'll dampen the spring clips with a heat wrap to eliminate the "twang" they can make when cold and I get too accelerator happy too soon. That being said, I loved the feel, sound and the response when getting on it. I can't honestly say what numbers are going to show but I know it was worth it. I will be getting a muffler of some kind because the days of just cruising around and not being challenged at every stop light are gone. Every kid in Cali with a pipe wanted to test or impress me. The "drone" at this point with no mufflers is more than most probably want. Again, no mufflers on this setup yet. I like the noise coming from a luxury wagon but there's something to be said about not showing all your cards right after a deal. I'd love BCRedliner's cutouts to a muffled system because there's also something to be said for just being the loudest kid in the room. I found I didn't need to downshift to pass quickly but if I did for funzies, that was quicker than before and the car announced its intentions with no confusion to other motorists.

Keep in mind, his wagon has a full s62 m5 conversion with a 6 spd, so he knows a fun wagon when he sees one. https://youtu.be/cqX-n_Qo198 This one was us getting stupid. Bad video reaction time led to the shortness of this clip but it was fun.

Does anyone else read 'SHLUT'? I like 546iT though. That'll raise eyebrows from actual enthusiasts.
