I planned out where I was going to route the exhaust, putting the mufflers at the front where the highest pressure would be to take full advantage of their sound deadening and adding in a x-pipe to equalize the sounds from both sides of the engine and add some more muffling. To make the x-pipe, I took two 90 degree bends and cut the outside of the bend off so each side was at a 45 degree angle to the bend and then welded both pieces together as seen below.
I cut each piece to the length I needed it and then started laying it out, mocking it up underneath the vehicle, starting at the front working my way back, tacking each piece together as I went. Then after it was all tacked up under the buggy I welded some mounts for exhaust hangers onto both the frame and exhaust pipes and pulled it out from under the frame and welded it all up solid. Here's what it looks like all together.
The dual outlets are on either side of the rig, right at the back of the frame. I got theses slip-on 3" chrome plated exhaust tips to give it a little cleaner and fancier look at it comes out from under the frame.
A video on it in action will be up soon!
