Huge difference! I did something similar when I bought mine. The only mod I felt it needed.Here it is as of purchase
And here it is with xpipe
Funnily enough, that's where those crazy Italians stuck mine tooIn mine, the In Car Entertainment is under the bonnet
Very nice congrats.Hello,
Picked up my new daily , a 2008 Sport GT earlier this week, very happy.
It replaces an Alfa 159 which I will miss but this has won me over in the few days I've had it.
Credit to previous owner keeping it lovely for the last 6 years!

Congratulations - identical spec to mine, except mine is DuoSelectNice , I have seen the vids.
I like how the xpipe doesnt change the cabin noise at crusing speed. Do the backboxes change that?
He can mod your existing boxes. That's what he did with mine and then painted and polished the tipsis the Jaren exhaust a refurbished OEM part? Can see Ebay listing offering "new part" for 795 and send your own for fettling
Thanks. My tips are in great condition already and the painting of unseen boxes is little or no concern to me. What else happens to the units, are they gutted of all noise reducing baffles and wadding?He can mod your existing boxes. That's what he did with mine and then painted and polished the tips
The spring loaded valve is fixed open inside and all the wadding (a bins worth) pulled out then rewelded back up hence paint.Thanks.

Maserati QPV Exhaust Internal Valve

Correct. The gases flow in through the valve which opens based on pressure and either exits through the small diameter exhaust tail via wadding. As it opens wider, the butterfly valve inside the large diameter opens to make it more direct and unsilenced. Ps. This is 4.7. Not sure if earlier ds were the same.Thanks Gaz
Had no idea QPV had valves or spring inside. How. does the spring operate, just airflow pushing it open when "pressing on"?
