Reproduction mufflers

Have a look on. P D Gough web site in Nottingham, UK. They sell in the US under the name Nuvalari . Not sure if that’s right spelling. Their uk web site has pics of what they make

 

Ansa reproduces the exhaust for the boxers, the mufflers, the manifolds etc. They aren't exactly correct but as close as you will get that isn't OEM. I would reach out to them and yes they are very expensive.

 

The muffler Nouvalari sent to me last year required cutting and welding of the left inlet pipe and the right side intermediate pipe to fit properly. Oh, and it took a 5/8" spacer on the left mount for it to sit level across the car. They wouldn't take ownership of the issue, telling me something must be off with my car. So I said "F... it" and just modified it to suit. Other than that, it's beautifully made, and sounds great

 

Ive also had to make Nuvolari systems fit and bell and the very expensive Ansa 365 boxer reproduction systems. I have a Tubi on my 308 but I didn't install it, it came on the car and looks to fit fine.

 

The entire range of 308 thru 328 is a PITA for mufflers and exhaust systems. Ferrari constantly tweaked/modified or updated some little but making it nigh impossible to mfg a std version for a given model. Mount locations changed or varied, euro vs USA, spacing etc.
So it's doable, but requires more then just model but also yr of mfg. And even then, it'll need tweaking to fit most times.

There's a fair amount of 'slop' in the fitment of the exhaust system, I've found it best to have the headers mounted, the rest is loosely in place. The mufflers mounted then go back and tighten up the system, otherwise you'll be fighting it.

 

I also had to the same with one outlet pipe. The other one wasn't a perfect fit but I wrestled it into place.
It certainly wasn't a case of unpacking the exhaust, sliding it in & doing some bolts up.
If I had known, I would have taken the car to them and taken advantage of their fitting service (I am in the UK). It would have probably worked out cheaper & quicker!
