I guess that's the valve then Brian. I'm just amazed the Biposto doesn't do the same with the valve permanently open....but then I haven't driven one.

The Bombardone exhaust is not road legal and is aimed at track racing which makes perfect sense as you are only using the higher rpm range the whole time

Depends what country you are talking about? UK it has no issues as the UK does not require TUV approval. The race use only badge on it is aimed more at Germany and Austria.

I agree regarding the torque loss though, although a remap soon sorts this out.

Our torque starts climbing from below 2k and peaks at 3k at well over 220 ftlbs. (On an IHI)

Porthos, can I ask if your stainless steel Monza looks a bit like what I personally think is a dog's dinner? Not the backbox itself, but the pipes. Mine (delivered early July, so far done 1000 dry miles) appear to show what some have described as oxidisation, and not to a small extent. Just all looks a bit old and pre-enjoyed. Also, the LHS of the backbox has a massive "X" scrawled on it in black marker pen??

I'll take a pic for you of mine, I think they are OK I have that X however.

here's a couple of mine  the oxidisation seems to around the welds?

 

good grief, yours looks even worse! I'll just up now and take what I've got, thank you very much, lol.

thanks for showing me yours, Porthos 

As for TUV approval benn, that's not what concerns me, actually changing your exhaust for a louder one (or modifying your own to be louder) is in fact illegal in the UK.

Don't get me wrong I've had modified exhausts in the past and probably will in the future but as admin it's not something I would encourage  That and having a family of police officers.... 

Ah yeah knew about that. Mentioned it another topic and someone called me a liar lol. Couldn't find an article proving it at the time though, thanks.

Like you PORTHOS, my old car never did it which is why I'm noticing it now.  I must admit it wasn't as bad when I filled up yesterday, started to get really noticable just under 70 where as it was from 50 the other day.

Yep sounds the same as mine, ha ha. I'll have a look later at it, but it is indeed over 50mph.

I do have a rattle on my exhaust that sounds AWFUL, you can hear it in the video around the 6 minute mark, it comes in at 3k and only just under. They are looking at it for me end of month

Oddly though this one is far far better than my 160, that had too many problems to list including a leaking battery that destroyed 20% of the engine bay, lol.

Hi Porthos, was wondering if there are any updates on your rattly exhaust?
I noticed a slight rattle coming from the underneath of mine the day I picked it up, and then a couple of weeks later I heard it again, strangely when turning left?

On friday night I went for a blast to the coast and back, and the rattle is still there, it comes in at a very specific 92mph (thanks to the huge digital speedo!), I'm thinking its exhaust or heat shield?
Anybody else with similar problem?
Overall though, I am loving the sound it makes, getting more pops now too!. It genuinely makes me laugh how loud it is when on choke

Thanks for that, I will keep an eye out for your dealers analysis of this problem. Was hoping it is nothing serious, and that it can wait until first oil change
P.s. I will post some pictures of the new car...if it stays clean for long enough!
