2 1/2 or 3 inch exhaust

[dmo1]

Anyone recommend which size exhaust would be best for my 429? It's .030 over, balanced with a mild cam. Dove heads with smog bump removed. Hooker super comp headers. Also, does the size of the h pipe matter?

Thanks

I think 2 1/2" duals is big enough for just about any thing. Cross over should be same size as the exhaust.
