I have Flowmasters on it now and I'm thinking about putting the Banks power pack on it
cherry bomb and coathanger
i also have a TJ that my cousin put a flowmaster in. i asked him to beef it up and he said that any other exhaust would sound terrible with the v6 engine that i have. so my advice is just keep what u got and get a muscle car if u want a nice sound.
I have a Banks on my 2001 and it sounds nice,not to loud just a nice rumble when you floor it.
