Hi Folks,
I'm just building a new exhaust for my van and I want to go stainless steel for durability. Now I've heard (some muffler firms say that) that you should weld in an H- or X-pipe before the mufflers (my van has full dual exhausts without any connection between them).
What good does that do? How does it affect sound and performance? Or is it Voodoo?
Thanks a lot,
Mad
