Speed Engineering True Dual Exhaust Prototype..
 

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
Sean

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.

Just arrived, here is a pic of the rear exit prototype. Everything will look the same except the natural steel will be polished as well. If everything fits good we should have the rear exit kit available by December or January.

Thanks
Sean

whats the price? and what muffler?

Looks really nice! How would the fit be for us 4x4 guys?

What size pipes?

06murder: We dont have a price yet, but we're trying to keep it under 400.00. Its a custom muffler we had made for us. Straight through design with thick insulation.

black00chev: Good. One of the trucks being test fitted on is my personal 2008 4x4 crew cab.

03sierraslt: Its all 3" dia.

Thanks
