Default LS2 Exhaust Questions: X or H pipe, 2.5" or 3", etc

I am installing a stock 400HP LS2 and 4l70e trans out of a 2008 TBSS in my 69 Camaro. I have switched over to a corvette intake & TB with long tube headers with 3.73 gears.

- How important is the exhaust size? Would I be better off with 2.5" or 3"? H pipe or X pipe.
- What would you recommend for header gaskets?

2.5" won't restrict your power at all right now, but if you were to produce a large amount of power in the future, 3" would be your better bet. H pipe will sound more old school and deeper, while an X pipe will give a few more HP (most of the time unnoticeable) and a louder but...more unrefined I suppose sound.

For stock and near stock power 2.5" is more then enough. If you plan on putting down 500+ hp then go with the 3".

H pipe or X pipe?
H sounds deeper and muscular like an old school V8, X sounds like a buzzing exotic european V8...your call as to what you want your 69 Camaro to sound like.

Go with OEM ones

The pitch is higher, but it in no way replicates a flat plane crank engine.
