what is a good exhaust for 2005 4 door civic that bolts on lıke the factory muffler but has a nice tone rather then the can mufflers.

also if i decide too purchase one does it void the warrenty

 

I could be wrong b/c I've never done a Honda exhaust, but from reading on here, when you just clamp or weld on a muffler using the stock piping, you will get that annoying baaaaaa sound that you hear blocks away. Most people on here have all-new piping made, at no larger than 2.5" piping. You can get it done at a muffler shop for not a whole lot of money. Also look into large-chamber mufflers, not the cylinder ones and you'll be quite happy with the results.
