Definately, you are not sending a text message here, it is frustrating to try and answer a question when you aren't even sure what is being asked. Take your time and write out a thoughtful, coherant message. Just asking what exhaust sounds good or loud doesn't give us much to work on. We need to know thing like:
-How loud?- We talking deafaning or just a good sounding, muscular note
-Is performance more important? (not all loud exhausts are good)
-Mild steel? Stainless? Aluminized?
-How much do you want to spend?
-Emissions legal?
Type out something like this next time
"Hey guys, I am looking for a new exhuast and wanted your advice. I want it to have a nice deep note but not so loud I get a ticket, and I also would like it to perorm well. I've only got $400 but I would really like Stainless Steel. And it also has to be emissions legal. Any ideas?"
So go ahead and re-ask and give us some more specific info and you will get your answer.
