Exhaust idea?

[1976SR71]

With all the mods I will doing on the Trans Am..I will have to do a custom exhaust.
An idea I have is to use 2 of these mufflers after the X-pipe.

Since it will be a 3-link... That will free up the space where the rear of the leafs would be I could hang a pair of these.

Do you think this will be enough to quiet a big block?
Is it to ricer???
LMK Thanx,
