I'm just about to put my 383 in my z28, so ihave started thinking about the exhaust. I want long tube headers with pipes going straight to the back of the car. I don't want to run any cats or have on an H or X pipe. Would something like this work?

Been done many times. Running long tubes is a perfect time for the benefits of an X pipe.

Loud as snot.

Unless you find a way to get the drivers side over/under the rear axle to have a rear exit.

I read once that having an X pipe is a good thing, as it equalizes pressure in both exhaust banks, so you dont have any kind of "popping" when you take your foot off the petal from WOT.

Not sure how much that applies to a long-tube header, because those cars run very short cramped headers, but it's interesting nonetheless.

Running an X pipe is a bad idea on shorties. The problem with shorties, is that they are not equal length to each other and you can have exhaust pulses crash into each other rather than work as a syphon.

Long Tube headers are Ideal for an xpipe.
