your saying in theory, although no mass is there back pressure will build causing power to be inconsistent somewhere along the rpm band? educate me if im wrong. this will only be tempoary, the turbo back that i want is on back order for another 2 months.... Trust me i'll wait for it, it has the 3' flow but its quieter than the stock exhaust

 

GUT THE BITCH!

 

I'm not sure with a turbo car, but everytime I've heard a car without a cat, its louder and raspier/ricier sounding. The cat kind've acts like a resonator as well. Why don't you try a resonated test pipe? You'll get the flow of a straight-through test pipe, without the horrible sound. Again, it may not make as much of a difference on a turbo car as it does on a n/a car, but if it does, it'll be well worth it.

 

4in downpipe and call it a day

 

Sound wise - I doubt you'll notice much of a difference if any.

To everyone who said don't gut it because it will run worse/improperly, you're all fucking idiots and need to shut the fuck up before I make you look like an idiot.

 

Don't make me look like an idiot, but why's that? Just curious?

 

He will get you drunk with him and then color your face with a purple sharpie and post it. Duh.

 

What causes the impeller on a turbo to spin? Answer = (X)

Why? .. because X on one side of the turbo spins the impeller (thus compressing the air) on the other side of the turbo.

Now, in relation to your answer in the first question (X), what does a catalytic converter do to X?

 

spic care to explain how i lost 15whp when i went from a HighFlow Cat to a gutted cat on my SR car?
