Re: Mufflers
 

Well I just got my Livorsi catalog!! Nice little cut out view of E-Series mufflers. I have to say they are like no muffler I have seen anyway. 81.5 decibels at idle on a 525 EFI is impressive. Wish they went in to a little more detail on how testing was done though.

I think from what I have seen these are worth a serious look for anything up to 550hp NA or 750hp blown. I think I will give them a call and see what type of warranty they have since they have moving parts inside.

Paradigm,

Did they mention anything about a loss of power? Please keep me updated on any further info you find. 81.5 is pretty quiet. What was the initial reading prior to the muffler install?
I think I would like just a little more noise then the 81.5, maybe 85-86.
