355 In need of a "quieter" stainless sport exhaust

Is this the new version Larini muffler released just a few years ago or the old version?

 

The factory exhaust is reasonably quiet .....

 

What MY is ur car?

 

Model Year?

 

Pretty much any SS exhaust with level 1 sound not level 3 and with valves to open wide. SuperSprint, Capristo, Tubi, Kreissieg, Nouvalari, Larini, take your pick. If anyone says they can feel a significant difference with loud vs quieter version exhaust from the same company they are lying. You can always do the stock one too, good luck with your choice!

 

No one is going to force you to buy and install the Bypass Exhaust Valve Kit. That's what that is referring to I believe. Just call them. Your text is not from Capristos site probably a reseller like Vivid.

Would seem so.

 

With a bypass valve, of course. That's not required.

I got tinnitus in my ears after having the Nouvalari SS, i am considering to change also, it was fun in the beginning but it's getting too much.

 

Yeah but it's heavy as hell....

 

Any idea how the new Larini sounds compared to Capristo?

Don't understand Eric. The 355 has a bypass valve to open the secondary exhaust path. . If you have a Capristo muffler and no bypass it straight pipes all the time.

 

And this caused how many 1/10s of a second slower lap times?

 

Contributes to over steer.

 

That must be it.

 

Ahh I'm thinking 348, we can have a bypass or not.

I suspect the issue with noise is not even so much wot, it's more below 4000 rpm on highway or around town, some of those exhaust level 3are loud as hell at low speeds where wer are 90% of the time on streets. Loud and drone, great if your 16 with a case of look-at-me-itis.[emoji3]

My nouvalari isn’t that loud at low revs.

Actually not for several reasons::
a) it takes mass off the rear of the car so the tires have less to hold and have relatively more grip,
b) if you lower the rear the amount the springs raised the rear due to less weight in the exhaust,
... the roll axis inclination remains the same and chassis/suspension geometry is not altered.

Thus, done properly, there should be a slight increase in understeer,

 

And constantly annoying when you are 40+ with tinnitus.

 

I have a Tubi Evolution (and cats deleted) and don't find it insanely loud cruising around town. With windows up it's quite civilized. Windows down at WOT it's loud and sounds great, but doesn't make your ears bleed. Cats quiet it down 5-10% (less than you'd think).
