Haha, I was thinking of going with the 14568. Its a bit bigger but I'm good with that. I have used them in the past and have been pleased with the sound.
I'm not a fan of dumps, especially in an SUV.

Dumps are obnoxious and if they are in the wrong place, do nothing but heat up an axle which in turn kills an axle bearing quickly!!!

You haven't seen a glowing red diff or discoloration on the metal pieces behind the exhaust exit? This can easily happen after a WOT run or highway/freeway trips.

Same truck came in probably 5 times in 6 months needing axle bearings all on right side.... After 4th time they refused to cover it under parts warranty, because all of them were cooked, last time he had to pay for it, he also went and had tailpipes put on it and hasnt toasted a bearing since.... Wish i had pics, but was a while back....

No I haven't seen it. Have you?? And I would never point my dump/turn down at my axle housing or tube end either. And I highly doubt speed inc. is going to sell a product that will damage drivetrain pieces due to heat exposure. Even if you axle is "glowing" that right there is a sign that you need to reconfigure you exhaust and continue to run the same setup. Also noting, there are plenty of trucks on this forum that run dumped, turned down exhaust and have never had damaged bearing issues. Exhaust gasses that far back from the motor aren't nearly enough to make the axle housing glow. Watch some dyno videos, the headers glow, and a few inches past the collectors glow(barely) but if you are glowing the whole length, like stated, there is an issue there. And a WOT pass isn't nearly enough time to cherry that cast iron housing, and neither is freeway driving, this is more then enough air flow passing under/around the vehicle to keep the temps at a reasonable temp.

Agreed, was more a caution or warning, than sayin their dumps would be or are pointed at axle..... Biggest concern is the obnoxious factor for some..... Just nature of dumped system!!!

I will agree with you that dumps/turn downs are a bit much for some folks. My self included...... Even tho I have a turndown, it is quite obnoxious. Hence the reason Sean needs to hurry up with this kit so I can swap my exhaust, and make tail pipes if I choose

Well, unfortunately we received some bad news this afternoon. We were expecting a normal eta with this kit. However, we just have been informed that the factory was having a hard time getting large quantities of all the pieces needed for the kit, and they pushed it back on their priority list. They have since gathered everything needed, and gave us arrival date of Mid January.

Thank you
Sean
