Dynomax bullets run in the $20-$60 range depending on length and pipe size
Jegs has a nice copy #555-30292 18''x3'' (about $44) that I ran on my 65 Belvedere BB 451,no X-over dumped at the rear axle.
Depends on how much street driving you do.You may consider them loud. I liked the sound, used them for a street class that required mufflers and also drove it on the street .My plan is to use them again on a 63 Belvedere project small block this summer.
Jegs has a video of the dynomax bullets in action.
