Here is my theory on the duals with 2.5" the SVT has 2.5" for single and it runs great so how can you justify using dual 2.5" piping??? you will lose power. I was thinking 2" would be about perfect.
I have already planed the side exit exhaust on my tour. it is the roush style. you have to move the fuel and brake lines of use some kinda heat shield on them otherwise you will have to vaporlock to worry about. my plan was to use the SVT side skirts and use fiberglass to fill the space between the jack instert and the side skirt making it all one peice then getting a square tip and cutting a space for it. or getting Roush side skirts and molding the tip exit to the SVT side skirts.
