Also in comparison the Wagner's add 15 hrsp to the 6 IIRC...im assuming there would be similar results on the SVT. However, what is the hrsp gain w/ the MSDS.
The MSDS headers do come with a y-pipe that connects the two headers, it replaces the factory one that most people here remove and optimize and re-install for far less. As when I first posted, I posed that these cheaper headers would be a great price and power match with those who have already optimized their stock y-pipes and are not ready to drop $660 to replace it and the exhaust manifolds.
I do not know about the gains on the SVTs, but here is a comparison of gains between Wagner and MSDS on the 6:
Wagner (Retaining stock y-pipe and two cats): 15 FWHP / 12 ft-lbs on a Mustang dyno
MSDS (Replacing y-pipe, removing all cats and Bosal axle-back exhaust): 12 FWHP on a Mustang dyno (Forgot how much torque he gained, its an old post on another forum, but since HP is just a measure of torque and RPM, its less than Wagners)
