Default Header to x-pipe distance?

So, 32.5" length, 1 3/4" od tube is the best header set up for a stock ls6 motor right? Whats the proper distance from the collector to the x-pipe? and is dual 3" exhaust needed for 450rwhp, or will 2.5" work as well and make as much power? Thanks!

I'm guessing this isn't the right forum but as close as possible would probably be best. But, most go for as soon after the tranny so they don't have to drop the exhaust every time they have to drop the tranny. 2.5" duals should be fine for 450rwhp.

techtrix,
GTObessor is right, this is'nt exactly the correct forum for the thread as stated. However, if you read the forum guidelines https://ls1tech.com/forums/advanced-engineering-tech/396223-what-forum-please-read-before-posting.html, I think the initial questions could be restated to comply with the intent of this forum. For instance:

How can I determine the optimum header length and primary/secondary/collector pipe diameters for a stock LS6 used as a daily driver/occasional weekend strip car?

How do I determine the optimum distance from the collectors for an X pipe?

How do I determine the minimum exhaust pipe diameter for dual exhausts to support 450 HP?

Give some thought as to how this forum is susposed to be used.

Steve
