Could any one tell me the big differences between this two mufflers, in terms of sound what's the less noisy.

Thanks

 

Ive got the Ovals and love em,nice rich sound especially when on the pipe.Dont know and havent heard the other ones.

 

I have the basics and like them very much but I believe the oval's are a little deeper sounding and all around quieter! To me either one is a good choice!
