So, Hooker is now developing a LT header in the Blackheart line, and these adapters will mate the two? What's the impact on ground clearance? I've ordered the midlengths but still awaiting them to be in stock and ship, so if it's worth considering a switch/wait for the LT's I'd like to know. I already have received the TD's that are set to mate to the midlength (70501413-RHKR)

The collector outlet heights and vector angles are all different between the various brands of headers as no efforts are made by manufacturers to standardize such geometry.

Hey Toddoky, excellent to hear that Hooker is working on adding Long Tubes to the black heart line. I just received my Black Heart Dual exhaust and it looks very nice. I will be installing it in a few days....I was wondering if you have any idea when the Blackhearts Long Tubes will be available? I wouldn't be able to purchase them until next spring but I am just curious.

I got mine all installed - lovin' it. Nice deep tone, and definitely louder. It's really quiet when just cruising but when you get on the gas even the slightest bit it lets you know it's there. Tips really look decent too - I like them more than I thought I would.
Install went well. Headers slipped right up into the engine bay with no drama. Directions were decent - helps to lay all the parts out first.
My only two negative observations on install:
1) The over the axle pipes seem to be in contact with the heat shield above them. No rattles or anything, but they are touching. I followed the install directions. I'll play around with it some more as time permits.
2) The O2 wiring...an extension is included, which works just fine for the driver's side. The passenger side, I am a good 3-4" short from the harness. I have new Denso sensors, but even the old sensors (look to have been replaced at some point too though, not stock) weren't long enough. Ended up just repinning the PCM harness and using both rear locations, which line up very nicely with the bungs.
Heading out to get it tuned tonight. I also had dynoed my car in June 2014 - it was stock. Only mods were an SLP lid, an LS7 clutch assembly (so, heavier), and AIR and EGR deletes. I put down 312/326. It's a 2000 SS M6 that had roughly 70k on it at that point - I have 76k on it now. I'll be heading back to the same dyno, with the same operator, on the 24th. I am hoping weather conditions will be somewhat similar. Only mods will be this exhaust (full Blackheart MidTubes & TD setup), LS6 intake, and the tune. So, I should be able to report back with a reasonably accurate comparison as to what these things added.

I'm extremely happy with this exhaust. Installed at the same time as my 1 7/8" Kooks LTs. All I needed to adapt them to each other was 3-2.5" adapters and a small section of 2.5" straight pipe. The install went super smooth and the car sounds incredible. It's rather mellow when cruising, which is surprising. Laying it on the floor and seeing the straight through mufflers I though this was gonna be ear shattering, but even without cats it's rather quiet for what it is. It screams when you get into it. I only have videos from a distance, but you can still get an idea.
Car has a stock bottom end and cam, only things done are an Ls6 intake, a lid, and the LTs.

I just installed mine yesterday and I LOOOOOOOVE it! It sounds way better than my old set up. Off road y pipe and magnaflow muffler. Like previous people have mentioned, it's not too loud at idle but even the slightest bit of gas and you know it's there. It really has made me excited to drive the car again. The car also feels smoother, it doesn't have nearly as much chassis vibration that my previous set up did. I had a buddy of mine mention that riding in the car doesn't feel like a message chair anymore lol.

I want to purchase the full Blackheart exhaust with the Mid lengths, but after finding out about the LT headers I am waiting patiently for those to release. I am curious about the difference in power and ground clearance

No, there's no current plans to create such an option, but I'll will forward your inquiry to the persons above me that make such decisions. I'm glad to hear you're another user enjoying the features and benefits the system provides.
