Akrapovic vs SC Project CR-T cold start on Tuono V4 1100 Factory

Sorry for the format, got so excited so forgot to place the phone in landscape mode...
This is a quick soundcheck on my Aprilia Tuono V4 1100 Factory from 2020.
Race map is on the ECU. Runs very good with the Akrapovic. Wanted to buy the SC1-R but got hold of the CR-T for half price and decided to try it.
It is extremely loud as everyone says on KZbin, you cant really understand it until you hear it live.
I put the decibel meeter on the saddle for reference. Its on the setting "slow reading" and is pretty accurate when compared to my physical decibel meeter.
I have paid for everything by myself so there is no sponsorship involved at all unfortunately.

Akro sounds better. Deeper tone... That SC would drive me nuts.

[@KhiemDomoto]

did you install another tune other than race map for the crt?

[@j0akim123]

Not yet. I want to test it first to see how it goes. Still winter here but that’s hopefully over within some weeks.

[@KhiemDomoto]

@@j0akim123 so no tune or race map at all yet? What are you planning to have?

[@j0akim123]

@@KhiemDomoto it’s the Akra race map on it at the moment. Need to ride it before changing to another.

SC sounds more aggressive, best exhaust for torque monster

[@goomaa88]

SC sounds extremely loud :)

[@myaccount6905]

Actually the engine loses torque due to the short muffler (SC)

[@j0akim123]

Have you taken it to a dyno and compared vs original or Akra? What was the difference?

[@myaccount6905]

No I haven’t but it’s a fact… the longer muffle of the Akra generates more exhaust counter pressure (if that makes sense)… check out the exhausts on WSBK bikes… none have a short muffler…

[@j0akim123]

You are welcome to share the facts so I can read it. I’m having both models and can switch pipes very easy so that’s good. There is a lot of torque so it’s all good with both pipes 👍🏼

[@myaccount6905]

@@j0akim123 I checked again.. short muffler will add extra torque at high revs and loose torque at low and mid range… Long muffler has the opposite behaviour…
