operated exos

[AY8686]

hi guys, operated my silencers, yes very bassy but in the cabin the drone is really wow.. but the outside isnt as loud as the cabin. Was told becos now all the new design mercedes exos design is hidden in the rear bumper, not coming out of the bumper thats why the cabin is louder then outside.. 

Any one can suggest how to increase the sound the other way round? Outer> cabin any1?

Will be very helpful if you state which Merc model you're driving.

My W204 is the exact opposite from yours. Loud on the outside, but only half the sound enters the cabin.

Guys do remember that the fiberglass stuffing will wear out in a few years so you will need to go back and redo your exos...

Hi there,

 

My guess is that it's non lta-compliant? Can advise on that?

And what happens when go for LTA then? Thank you.

Operated exhaust are ""LTA"" compliant.. Those experienced modders will know what I mean..

Yes yes of course it is "LTA" compliant... till the day of inspection.

With new stricter punishments introduced in Nov'15, operated exos (decat) can be a very unwise option.

What qualifies one to be "experienced modders"? Hahahaha

[Anle]

Better don't share it here.. Else LTA might be reading his haha

[BabyA]

No worries, LTA knows about decat or the operated exos thingy... jobs of operated exos existed as long as the rules was implimented and yes they know.

Asking because experienced modders and expert modders are different mah, former can also mean people who mod for years/decades without knowledge of the latest tech which serves many old practises pointless.

Just buy quad exhaust better, Lta approved no worries

On that matter; which LTA friendly exo is the quietest? Have to please both the gahmen and the gahmen at home.

Excluding factory equipped exos...

1) LTA Friendly Exos (aka Gahmen friendly) = LTA Compliant Exos... just pick the exos with musical notes that u like.

2) LTA Unfriendly Exos = Non LTA Compliant Exos = Cannot pass the LTA sound Db standard = Totally fail the Euro-V emission standard (come 2016, is Euro-VI emission standard)

So finally, your choice IS obvious.
