Remove resonators or install x-pipe?

Remove the two resonators OR do a muffler delete. Start with the delete. If you like it you can have pipes installed to extend to the bumper.
The 430s have a center catalyst that I do NOT recommend replacing with an X, H or Y pipe.

My reason for saying both is because my G8 GT Pontiac (different of course) has th 6.0 V8. I actually went with the H-pipes instead of the X-pipe deleted both resonators and added the magnaflows and it wasnt very loud until i got on it. Even then it was enough to make heads turn without sounding like a exhaust job on a Harley at WOT!

The single center pipe is 60mm = 2.36" OD
The twin pipes from the engine to the Y are 50mm = 1.97" OD
The way the stock Y pipes works is better than MOST Y or X or H pipes you can find.
Why do you want an X pipe? Sound?

I was thinking X-pipe for a little more grunt and flow, thinking maybe 5hp, I dunno. Gotta pull everything down for the TC and header install here anyway. I won't bother having it done if the differences in flow are that marginal, though.
I feel kinda stupid, but to confirm, the 400's exhaust layout is this, correct?:

also, it is more likely that you will not gain anything or even loose by changing the front Y pipe
