Speed Engineering True Dual Exhaust Prototype..
#472
I was thinking the same thing. So, I went out and weighed all my stock pieces. Manifolds to tailpipe and came out at roughly 119 lbs. Not sure what the Speed Engineering kit is tipping the scales at though since its on the truck already. Factory exhaust was the 2.5 dual cat setup like the 3/4 ton trucks. I would say from what I remember the new stuff "feeling" like it was quite a bit lighter compared to factory. Light enough that I was concerned about what was actually in the UPS boxes before I opened them and laid everything out anyways. Still digging this kit too btw!

Do return customers get a break?
We just got our 1999-13 truck true dual exhaust prototype back in for fitment verification. Came back looking pretty sick. Thought you guys would want to see whats to come. If fitment goes smoothly eta is approx 3 months out for our first batch of them.
The exhaust will bolt up to all of our truck longtube headers from 1999-2013, single, crew, and extra cab trucks.
Thanks

Ok, thought you guys would enjoy some actual dyno numbers of the true dual exhaust.
Vehicle:
-2008 Sierra Crew Cab 4x4
-6.0L Engine (Stock Bottom End & Heads)
-228 Camshaft
-Our 1 7/8" Longtube headers
-Stock 3" Cat-Back w/Magnaflow muffler welded in.
1100MD Mustang dyno:
Stock Cat-Back w/Magnaflow Muffler
-343rwhp
-331rwtq
Our 3" True Dual Exhaust
-367rwhp
-350rwtq
Gain: 24rwhp/19rwtq
No other changes were made to the vehicle besides the true exhaust swap. Headers were already installed. The thing we were most surprised with was the torque gain across the board. It didn't loose any bottom end. The larger 3" exhaust actually gained torque across the board.

We haven't never heard back from those few that purchased our systems for long beds. I am assuming it worked just fine. PM me a picture of your frame. Specifically between the rear end and your transmission cross-member. Once I see which frame you have I can let you know which kit would be the best shot at working for your truck.
