i think i have about 8-10 hrs (about average for a full system) into that one. Alot of the time comes from that each tube needs to be welded together,---so its weld a little--wait for the welder to cool---weld a little,--- wait for the welder to cool, etc, etc. That sytem was tacked with a mig then fully tiged together. As you can see, its an x-pipe, merged into a single 3", into a flowmaster 3" in and dual 2.5" out. I welded chrome stainless tips onto the muffler outlets after i painted the whole system.

To be honest, i hear that it sounded awsome, but i never got to hear it myself. I usually go to where the car is to do the work, and this one had some funky issues that without the owner around, i didnt want to start it myself.
