Have any of you experienced an increase in the interior resonance levels as your muffler ages?

 

I am told that all exhausts get louder with age. I believe my
Europipe is louder now than when new. I don't note any
resonating though.

Yes,

My Europipe Quiet is really not quiet anymore, especially in the interior.

 

Mine is maturing BEAUTIFULLY!!!! I love listening to it SING!!!!
It is akin to having finely tuned trumpets. Alright I know I am being ridiculous but the sound really is intoxicating. I find myself purposely holding out the revs in the gears just to listen to it!! I just love it!!! I guess you could say pride in ownership, huh!?

 

I enjoy the sound of a nice exhaust as well, but interior resonance or booming just wrecks it for me.

 

I agree EP II Quiet seems a little louder. I suspected this would occur and that is why I didn't go with Loud. Now this may be my imagination but either way, it SEEMS louder but I am very pleased.

 

Mine has gotten a little deeper lows over time. But at wide open it is the same thunder growl. And the cold starts are intoxicating. I am proud to own the Stage II loud.

It the best overall exhaust out there IMHO.

 

yep!

 

anyone got cel problem,whetner running with upgraded ecu or stock ecu?

 

It really depends on how you define resonance.

My EP 2 Loud battles my tire noise (14,000 miles on the tires, and they're pretty loud) between 2000-2500 rpm. I suppose that's "resonance", but with new tires, I expect this to go away...back to no resonance.
