Are there any "cons" to going true dual?
Hi guys....so i am close to going the true dual route, and obviously the gains have been proven, my question is....are there any cons to going true dual? Does the car lose low end tourque? etc. Just curious to know. thanks guys.

I would think that the car would be undriveable with the amount of noise the car would create without mufflers. Some of the BMW 335I guys have tried the muffler delete and it's bearable on that car because the turbochargers do a good job of quieting the exhaust. That won't be the case on NA V8 like the IS F.

From what other have posted. Going with a something like the joe-z will yield a slight sound increase and the issforged will be a bit louder than that. However, due to the sound dampening put in the Lexus, the car is certainly still drivable.
Now if you decide to go the header route also, I'd wait till something comes out w/ cats on it before making a purchase, if your concerned with noise.

For sure the noise increase will be there, but I'm not opposed to little bit more "presence" and NICE grunt, but is there any performance give...say possible due to less back pressure a little loss in low end tourque? Etc. I ask because I've heard sometimes cars losing HP and TQ when doing an exhaust. Thanks guys for the input in advanced.
