This is my 03' rubicon. Since I have bought it all I have really done to it is put 33's the chrome step ups and some work to the inside(sound system, etc.) Now that I am out of college and actually have a paycheck that I can spend, I am wanting to make it sound a little better but really know nothing about exaust systems or anything. I picked up a friend where he had dropped of his car to do admissions and I noticed it was also a custom exaust place. I talked to a guy that worked there and they said they could put a magnaflow 40 series muffler in for 170 without tax. Is that all I need and is that a good price? Any help is appreciated and now that i found these forums Ill prob be on here quite a bit.
