I have read just about all the posts on this topic and I just want to clarify my understanding for my specific set up. I have Roe HF cats, and Corsa cat backs, stock headers on a 2004 Paxton SRT. The sound is still a little raspy for my taste and I love the sound clips of the Belanger full and cat back systems. But I see that a lot of people stick with the Corsa cat backs for the drone reduction. I don't want a loud exhaust. I'd like to get the Belanger deep growl with little to no drone. My conclusion is that I can get this by just adding Belanger headers to the existing system that I described above. Is this right? Will the Roe cats mate with the headers and will this get me the low mean growl that I want? Or are the headers not worth the money? Any other suggestions are welcome
