pictures of y pipe?
 

does anybody have any pictures of the old stock y-pipe, and the new aftermarket y-pipe that is less restrictive? and possibly some before and after pictures installed on their truck?

i have a 2500 heavy duty, i'm sure it already has a less restrictive exhaust on it, it has no resonators. and it's 3" all the way from the y-pipe. it has the left bank and right bank separate with their own cats. then it comes to a y-pipe and runs 3" to the muffler to the right rear of the truck behind the right rear tire. i threw on a flowmaster super 44 delta flow muffler, as the stock muffler rotted out.

I removed my Y-pipe all together, had the shop cut the pipe after the cats and run 2 pipes down into a dual in/dual out muffler. Much better,

i will probably go with true duels later down the road. not sure what i want to do yet with the exhaust. alot of options.

Before your y pipe is what comes stock on the truck. Check the long tube headers DIY for some exhaust pics.
