458 exhaust - as loud as possible legally

I have a 360 with the Ferrari racing exhaust system in it -- a monster -- very loud. What is the loudest system I can place in a 458?

 

No valves, no mufflers and no cats

Paging Synergy..

 

I'm glad you're not my neighbor.

 

Ha!

I hear Carlos 458 all the way in the next city.

 

novitec with test pipes

 

I wish he were my neighbor.

 

You are speaking my language Carlo!

 

LOL hey give some exhaust advice to the man!

My 458 exhaust advice is IPE F1 catless or whatever you are running these days Carlo!

This will surely wake up the neighbors!

 

IPE F1 catless rules!!

Make sure you order the Titanium F1 version, NOT the Evo version!

Is there a huge sound difference between the IPE headers + catless IPE and stock headers + catless IPE?

**** the neighbors. Who cares what they think. In today's culture, it's all about "ME". Heck that's why I bought a Ferrari

 

I have catless IPE with stock headers, but am considering aftermarket if they help the sound.

Technically - removing or tampering with the cats will make it "Not Legal" in most states. With that being said - going with a NON-Valved Exhaust System is going to be the best bet. There are quite a few options. In the state of California - the restrictions are getting heavier and heavier so we are unfortunately unable to sell an exhaust with NO CATS unless the vehicle is outside of the state of California.

So the question really is - do you want to be legal (with cats) or Not Legal (catless).

Obviously the catless system's are incredible sounding - Case In Point, the Novitec Extreme Exhaust System

You also can do the Capristo, Akrapovic or IPE system as well! Give us a call - would be more than happy to help you out!

 

Amen, we all know the people on the street referring to the driver of a straight pipe car going by as an ******* are just jealous.

 

Amen X2, if I don't get at least one f-word per outing I ponder another

Mine is so loud l can't hear ANY words, let alone F-words. So l am fine with the stock system with the baffles open all the time.

Can't hear any f-words so people must love me. People wave, smile, give me thumbs up, and take lots of pics on their cell phones. I just love to make other people happy!

 

I need to move wherever you filmed those clips...stunning.

and great car!

 

Absolutely love the sound of catless IPE with stock headers; however, I live in CA (good and bad thing) and want sport cats. IPE catalyst pipes are integrated into their own muffler system. So, in my case, I'd have to ditch my Akrapovic exhaust to run the IPE cats. Ain't gunna do it - wouldn't be prudent. So, anybody have experience or comments about Capristo cats? I'm leaning in that direction.

 

The question was, what is the loudest LEGALLY.

None of those catless setups are legal in any way shape or form in most countries and US states.

I believe Capristo makes some pretty loud setups where there's basically nothing to muffle the sound other than the cats once the valves open. However, what's the loudest legal system also has to do with the maximum allowed level where you live. Some places will allow you to run nothing but cats, while others still will have you running cats and some kind of muffler to meet restrictions. There are probably some places around the world where you can run a true straight pipe setup with no cats, no resonators and no mufflers.

 

I'm pretty sure the best legal setup is going to be novitec headers and high flow cats with the exhaust of your choice

 

If sport cats are legal where you live that is. They are not here in the EU.

 

really? I wasn't aware. I thought the US had the more stringent emission requirements. my fault

 

The stock cats are very restrictive. I did a valveless exhaust for my friend and it definitely wasn't as loud as expected. Even if you run the car with no exhaust at all its not loud. It just sounds like stock with valves open.

I wouldn't see headers making a difference since the flow will still travel thru the same restrictive cat.

I'm building my buddy test pipes next and will report back.
