Ok so i got may MXP exhaust and Berks yesterday and had them installed today. Sound good but have one issue, there is a small noise (almost chime) coming between the flex pipe and the resonator at around 3000-3500 rpm (left/Passenger side). Everything is clear and nothing is rubbing. The guys at the muffler shop say it is a bad resonator or flex (y-pipe). However MXP says that maybe they over torqued or have the pipes somewhat bent. It is not a huge noise but i do hear it. Anyone have any thoughts.

 

Is it when it decelerates? Its almost like a hissing sound and thats normal.

 

yes exactly!!!!....but on only one of the pipes the passanger side. At least that is what i noticed when i took it back to the shop and ran it while it was on the lift.

 

Did you use new gaskets?

 

all the new gaskets and bolts that came in the box yes

 

Its normal, anytime you replace the cats/exhaust that will happend. Every car has it, as a matter of fact I think mine went away. Its not the exhaust man, your fine

 

that is what the guy at the shop also said that they have installed a bunch of catbacks with HFC and they always have some sort of sound. Do you remember if your sound was on both pipes or just one. Also how long do you think it took before it went away (or are you just used to it now)

BTW it does sound nice and deep

 

LOL It's normal, check out my fast intention setup. You can hear the hissing too.

 

Oh it's very normal, wait till you hear those long tube headers! Hissing like a pissed cougar lol

 

Wow, your car sounds awesome!
