360 silencer replacement options

Think you are going to be limited due the design of the system, since the cat outlets connect directly to the muffler. Most of the aftermarket systems and the factory CS system connect to the cat outlets. If you like the OEM system, you might be able to have someone weld a bead around the edges where the heatshield is just spot welded to the box. However, since the OEM heat shield is split, you are only solving half the problem as mine was leaking powder along that seam as well. I now have the CS system on my car and as long as I keep my foot out of it, it's pretty tame sounding. If you know someone good at welding, they may be able to take the heat shield off and remove the insulation which is the source of the white dust. But to do this, you have to remove the exhaust and if you are going to that much trouble, you might as well replace it.

 

No, it's completely different. Aldous has a good article on his site that shows you the difference as well as a way to modify a F430's exhaust to fit the 360 and give you the same CS sound

 

I’ve rebuilt a standard one using Morgan superwool insulation. It takes about an hour to strip it apart (once off the car!) and you need a tig welder to tack the heat shields back in place.

Works perfectly. A lot less heat and no white dust. I’m about to do another one

Actually, the CS exhaust or the optional racing exhaust for the 360 is a direct bolt on replacement for the standard system. Problem is finding either of those in good condition for a reasonable price...saw a used one for 3k that came off a car that must have melted to the ground in a fire...

The 430 uses the an almost identical muffler assy. and as mentioned, you can modify 430 tailpipes to fit a 360. You cannot use the standard 360 tailpipes with a CS/430 box as the cat outlets attach to the tailpipes rather than the muffler inlets as they do on the standard 360

 

Tried to modify my post but the clock got me. Just to clarify, the CS/430 silencer is a direct bolt in for the original 360 silencer. It will bolt up directly to the cats or test pipes, whichever you have. The tailpipes, on the other hand, are a different animal. You either have to get the correct pipes from a CS or the Racing Exhaust package, or modify 430 pipes as mentioned. I was lucky and managed to obtain the entire kit still in the wooden crate. The Racing Exhaust package is getting harder to find at a reasonable price so modifying a 430 system is the most economical way to get the "CS" sound.

The standard 360 pipes will not work and cannot be made to work (never say never...but) with a CS box due to the attachment location of the pipes.​

 

I'd say a few things to consider, Joe from fabspeed said the 430 Muffler is indeed not the same thing as the Challenge stradale.

"A couple of things to consider.
Yes the Ferrari oem challenge straddle muffler and the oem 430 muffler have the exact external size and shape. Therefore the mufflers are interchangeable. However Ferrari has different part numbers for these mufflers and Xray inspection shows the internal designs are quite different and the sound was different ......the 430 muffler is more restrictive internally and attenuates controls the sound more versus the straddle coupes muffler."

Modifying the tailpipes is for the 430 system is no easy feat as getting them to line up out the bumper just right is easy to screw up.

Challenge stradale systems pretty much NEVER come up for sale, ask me how i know for the past year.

The factory 360 performance system is valved and made by tubi, sounds great/better than the original coffin sized boat anchor on the back of our cars. It can be found at Ferrari dealers around the country, just make some phone calls.

 

You need a thin cutting disc and first remove the band that covers each end, then each end cover has 6 welds you need to cut off. The secret is to remove as little metal as possible to leave some for reassembly.

You then need to unfold the seam that runs along each side and remove the covers. There may be a few tacks on these pieces on the underside but on mine they had all split. If not grind them off.

I cut 13mm Morgan Superwool to shape and held it in place with spray mount contact adhesive (it burns off on first start) and assembly is the reverse. TIG weld the same points and tack on the straps which are purely cosmetic.

LP360,
The 430 exhaust does NOT cause any ill performance issues. It is louder and in some communities this is an issue. The 430 exhaust also does NOT cause any CEL's because it is a modification AFTER the last O2 sensor.

In case anyone wants to try modifying an OEM 360 muffler/silencer. I have some lying around that I'm willing to part with for cheap, though you would have to cover shipping which is a bit pricey due to the weight of the units. PM me if you are interested

 

Other than for concours originality, why do people not swap out the defective OEM silencers? They weigh a ton.

Need4Spd,
I believe that some people still prefer the original silencer/muffler due to personal preference of sound, cost or due to local regulations/rules limiting the noise that a car can emit. The latter is oddly a grim reality for some.

 

Thought about this before I started mod's on my car....take the original box, open it up and gut it, put in a x-pipe with a y valve similar to the CS system but inside the box. Weld it back up, wrap it in the stainless shield and have a factory appearing system, with a slightly more aggressive exhaust note!

 

All good reasons.

Weld up a custom exhaust using Magnaflow mufflers, stainless tubing, and tips of your choice.

I prefer Miller welders.

 

Does it really have to be Tig welded? I have SS wire for my Mig. Wouldn't that work?

I do have a Tig, I just can't figure out how to teach my self it.

 

It’s welding thin stainless sheet metal so for me TIG is the proper solution.
MIG may work but I suspect you’ll blow holes in it, although that is speaking for myself as a fully signed up pigeon **** welder

 

Hi. A great Job. Where did you purchase the superwool. I've seen superwool on amazon but no reference to Morgan. I want to make sure I use the correct stuff. Thank you.

 

I just bought it from eBay....the 13mm or 1/2” thickness.
