Here's the deal this is probably gonna sound really dumb. In my hurry to get a louder exhaust on my truck I put a cheap system on because I didn't have much money. I want to get a really loud good looking exhaust I was thinking a flowmaster 10 si/do with dual pasenger side exit behind the tire. My dad doesn't want me to get anything else because he says it's already loud which it's not. Can anyone come up with some ideas of some chemical or something that I can put on my muffler or pipe that would cause it to rust really fast like within a couple months so I can get the set up I want. It's alumanized steal muffler with a small section of alumanized steal pipe. I know this is a dumb question but I'm sure we can come up with something.

 

Water vapour or moisture can cause it rust. so you can try out with water if you want to rust alumanized steal muffler.

 

Do not try to rust your exhaust on purpose. It can break fast and be unsafe. If you want a different sound, save money and replace it later. You can also try removing the muffler or adding a different tip to change the sound for now. It is better to wait and do it right than to damage the system on purpose.
