575 exhaust upgrade for a newbie

Yes. Maybe that’s the best option for me to start with the valved mufflers and see if I need more. Do you have a video of your cars sound? And how would you describe the sound.

 

Still very Nice! Had no idea the 575 boxes were THAT heavy. Always thought the 456 had the biggest boat anchors, for the more 'family sound.' Im sure combined with the full Fabio system, you can approach 100lbs

 

I have both OEM mufflers. The 456m felt heavier most of the weight is in the pre-cats/headers.

I had Fabio’s full set up > OEM mufflers…. while expensive it was actually very quiet and refined valves closed. That’s why I eventually switched to Fabio’s mufflers

 

Yes, I always do valved exhausts now. When closed the exhaust is quite quiet. Also note, Fabio went through great effort to eliminate ANY drone. I can attest that his exhaust has no drone at all and is very pleasant. I ran just mufflers with stock straight mid pipes for a while, then put the rest of the full setup in. I have videos of all of the cases if there is interest.

I have many others but this is easiest access quickly. This is the full setup.

 

Fabio is doing xpipe for me, we're a bit behind schedule

 

This sounds amazing! Thanks for sharing. Do you have a video of only mufflers?
Incredible color combination of your 575.

 

Thank you! I do have some, here is one i uploaded to Instagram just now.

Original Fabio exhaust mufflers for reference. This is stock straight pipes and headers with just mufflers.

Thanks for posting buddy. Sounds really good. I think this will be enough for me. I am leaning towards getting the valved mufflers before doing anything more. If I need more I can get his H-pipe too.

How much cracks and pops does it give? Personally I don’t like too much of that.

 

Dumping the mufflers (center and rear) for straight pipes with valves in the closed sounded very similar to stock while driving. Likely louder outside the car.
Swapping from 575 manifolds to 550 manifolds changed that dramatically.

 

With valves closed you don't get any, with open you get some. With yhe full setup you get a lot more.

 

I have OEM straight centre pipes and the valved mufflers and none/some is exactly it. I did appreciate the relative quietness of this set up with closed valves on multiple long drives recently. Even then, there was enough going on for other drivers to lower their windows to listen to it.

 

Definitely get valved for that reason!

 

Thanks for the inputs gentlemen. I am in contact with Fabio. He recommends H-pipe+valved mufflers. I think I will go for that.

 

Does anyone know if Fabio’s manual bypass opening kit can open the valves on the stock exhaust?

I use this to control my various valve exhausts I tried on the 575:

Fabio seems busy at the moment. He hasn’t answered my email for a little over a week. Manufacturing times are up to 1.5 month. In Denmark we store the cars in winter months, usually in the beginning of October. By the time I get it and installed summer will be over.
