Where did you find headers with 1-5/8" collectors? Anyway that's WAY too small for a 416. 1-3/4" collectors works good, but the 1-7/8 will benifit your top end a lot more. A true 3" exhaust is the way to go too.

Are these your headers?

They look like 1-3/4" primaries. What a good deal! Man, I paid about $800 more for my SLP headers.

Here's a good selection of X-Pipes:

Ditch the CAT's completely and go with a 3" true dual exhaust.
