Nouvalari SS question

Does anyone know if the Nouvalari Super Sport exhaust for the F355 has 2 sounds for when the by-pass valve is open and closed???? Reason I ask is because I had it on with my broken bypass valve wired open and I didn't like how loud it was at idle and when cruising. I put my OEM exhaust back on. I'm thinking of getting a new (functioning) bypass valve and trying it again. I miss the scream at full throttle

So would a functioning bypass valve help?

Also note that I have no cats, so a functioning bypass wouldn't help simply because of the cats muffling effect.

hi there.

I'm running a Nouvalari SS.

yes indeed there is clear distinction in sound at idle/cruising and when bypass opens.

I have no cats either. idle volume is reasonable with a functioning closed valve.

and has nice scream at full throttle open valve.

 

Look up P D GOUGH in nottingham in the uk as they are the makers- look for gallery and you will find a load of pics of the systems.
Also contact details so you can ask them for info as very helpfull

 

So P D Gough and Nouvalari Engineering are one and the same...?

There seems to be no images of a 355 exhaust on the Gough website. Also, the headers photographed on both their websites appear a different design. 4-2-1 on the Nouvalaris, 4-1 on the Gough page.

Intriguing.

 

They have an e mail address on the web site, the images are off customer jobs but not all , u can always ask them as very helpfull

 

I have sent them an email. Cheers.

 

hmmm if they're the same, I wonder what the price difference is (markup) between PD Gough and Nouvalari

 

Their building's are within a minute of each other.

Will see what information comes with my enquiry.
