i'm debating whether or not to install my un-resonated test pipes... because they aren't resonated... when i had them on my stock exhaust it sounded fine, but i'm scared of how loud they'll be when i install them....does the resonating help muffle the sound? or does it simply act as a resonator (what's the difference?) btw i have a custom exhaust....

 

ahhh anyone?

 

I heard people say that un-resonated test pipes are a bit much on any exhaust, and I assume that by going custom, you got something fairly aggressive. IMO go with the resonated test pipes or some HFCs.

 

hmm... so there really is a sound difference between resonated and non-resonated... cool thanks

 

rasp....tons of it, if you like you stock exhaust note but would like to amplify it go with resonated test pipes.

 

A muffler is just another resonator made to filter out other lower pitch sounds that the resonator in the exhaust piping does not... So yes, it should be quieter.
