glad u got my point i thought that less restriction=more power, backpressure comes from the turbo manifold right? u'll get faster spool with a bigger pipe i was being sarcastic about the 3.5" BUT IT WOULD BE NICEEEEEE

not really sure that it comes from the manifold, im pretty sure that its when you let go of the exhaust, air doesnt get sucked in the exhaust pipe and travel up the exhaust=loss of hp

The most efficient exhaust for a turbo is supposedly a 6" long cone coming off the back.
Turbo's operate best with no backpressure.

he is right, the turbo itself creates enough backpressure for the engine, after the turbo you want the largest exhaust you can fit.

You can't imagine a slight tapered piece of tubing coming off of a turbo?

Small at the turbo, tapers out from there on.
Fab up 3" exhaust with no muffler or anything. Paul runs straight 3" with a straight through resonator, sounds awesome(in videos).

A resonator keeps your car from sounding like a ricey piece of ****

Last night my girlfriend came home earlier than she ever has and caught me, naked, watching ****, and stroking it with a mask and snorkel on.

There's not really much to say at that point. She walked right past me and went into the bedroom. I quickly turned the **** off, put on some pants, and took the mask and snorkel off. Five minuets later she came out of the bedroom and asked how my day was... it was like she didn't just catch me throttling myself with a mask and snorkel on. The rest of the evening went as normal. We had baked chicken and green beans for dinner, and then watched the simpsons.

I don't really don't know what else to say.

Yeap, every time I let go of the exhaust air get sucked in the exhaust pipe and travel up and it's just kills hp gotta put something to give me more backpresure to stop it and more backpressure=more hp. I heard approximately 3.125001" exhaust is better than 3" cause too much much pressure on pipe=loss of back pressure=loss of hp=more air up exhaust getting sucked up=more turbo lag cause EGT's go down. Don't want that we all know you gotta have back pressure to make hp....
