I just got my Mangaflow catback installed. The sound is nice, however, the deep sound goes right through the Cabin, making it unpleasant in crusing.

I am think adding another resonator to the existing resonator magnaflow come with.

Stock has 2 resonators right?
Do you think another resonator will help with the deep sound level reduction? will it kill my power?

 

i dont know but i would have just gone with a greddy se.

 

Greddy SE doesn't produce hp whatsoever.Fact!
