3" cut out exhaust valves

[Rocco]

what about it?? i´ve saw some of them liying around ebay USA,for a "nice" price,but i am not sure about the perfonmance of it?? there are some manuals and others electrical controled

me for example i´ve got a full straight 3" pipe since the turbo only saving the last silencer that cross the rear diff.

th sound of my car it is like a V8 in the low Rpm´s, but for sure will be better sound with a cut out 3" valve just before the last silencer ( because now i dont have any intermediate silencer and any cats or any Y pipe

apart from the lovely free 5 cylinder sound....would gain any performance advantage??

Hey Tomas! Como te va? oye, yo no sè como funciona con la ECU original, en mi coche yo andaba con la VEMS, me hice el escape a mano con un DP de diseño propio, luego un tubo directo de 72mm donde el tubo se dividia en 2 partes, una para la salida de 72mm a travez de la valvula y la otra de 55mm dirijida al ultimo silenciador original. Dicha valvula (que posteriormente fue activada por la presion del turbo cuando pasaba 7psi\0.5bar), siempre con el K24-7000 soplando 1.3bar de boost maximo. Con la valvula cerrada, el coche andaba, si, pero de los 290hp sentia como 200! algo asi! Una vez abierta, ya sea manualmente o pneumaticamente (+7psi de boost) el tiròn que sentias no era normal! Como quien dice la diferencia del dia a la noche!
El llamado spool-up era inmediato, el sonido...pues...sonido de mis sueños! En el link que voy a poner, mi coche sonaba EXACTAMENTE igual, porsiacaso en mi canal (fab069) de youtube esta algun video con el escape abierto, desafortunadamente no hice videos del coche rodando y dando lo mejor de si. En conclusion, te recomiendo de comprar la valvula ciegamente! Hazlo y apurate! hehehe un abrazo! Que flojera ahora tengo que escribir todo esto en ingles hahaha

Now in english...
Hey Tomas how are ya? Dunno how does it works with the stock ecu, I was running the VEMS, I did my exh by hands with my own DP design, then a free flow 72mm (2.83") where on it's end it was divided in two... one tube got through a valve and ended on a 72mm tip and the other one of 55mm to the rear main and oem silencer. The valve was lately activated by a actuator everytime the boos press reached 7psi\0.5bar, always with the K24-7000 and 1.3bar of max boost pressure. With the valve closed, from 290hp I felt only about 200! Or something like that! Once it was opene, manually or pneumaticly above 7psi of boost, the pulling power was really amazing! A difference from the day to the night! It had inmediate spool-up, the sound...the sound from my dreams! On the next link there's a vid of a coupe that had the EXACTLY engine sound as mine, and on my YT channel (fab069) there is some vid of mine with the opened exhaust. In conclusion, I fully recommend you to buy the valve
