Hey I have a chance to get some 7in Irrigation pipe from my buddys house and im thinking about runnin a single stack on my truck the only problem i have is its aluminum idk if i can weld to that with metal and how would i reduce down to like 4-5 inches at the base?? I plan on making a cat stack but idk how it would work? If yall can give me advice i would really appreciate it!
