I have recently bought a '93 348tb with a sports exhaust that is being de catted this weekend.
I understand the exhaust thats on it is a Borla and is quite a small box.

I've just been out in a 348 Spider which sounded completely different - My car has a real induction noise as the air filter feeds from pipes behind the quarter glasses. These are obviously not there on the Spider.

The 348 Spider had a sports exhaust with the cats on the same as mine but it sounded more like a 355 ?

Is this due to the later engine or a different make of silencer or the fact that the intake pipes aren't behind your ears in the Spider ?

I have a 93 Berlinetta, de-catted with Tubi.

I used to have a 93 Spider, de-catted with Tubi.

The Spider seemed louder and higher pitched. I can only assume that on the later engines (GTB/GTS/Spider) the higher plenums hid a slightly more aggressive cam?

SPider/GTB/GTS had a higher output engine 320hp rather than 300hp so obviously a few tweeks were done to the engine by ferrari

But what tweak would it be to make it a different engine tone ... I can only think of the cam.

See you next Friday Rich ... unless you are getting there Thursday? If so, we'll see you then.

Best clean car, shoes and suit, in no particular order smile

I'm not saying it makes a bad noise, the noise is awesome just different than the Spider. The De Cats should give it more of an aggresive noise I'm hoping ?

Sorry Trace I've been working quite a bit recently - I'll bring it round and show you and Pete at the weekend cos I'm off ( after the De - Cats have gone on ).

I reckon the sound is down to the fact the Spider is GTB / S Spec with different Plenums.

Yeah should be - My mates are going in the Lemans Blue 355 and rosso 355 gts.

I'm in tonight if you n Pete want to come round for a look and sort out going in convoy if you like.

Sadly I can't Tracey ... Vic has swanned off on a girls long weekend to Spain and I am left looking after Gabby and Max ... I can't even bring them as our socialite 5 yr old has a party on Saturday and another on Sunday!

Me n Max'll just stay in and watch the Ferrari race on Sunday.

What? There are other teams in it too?
