Muffler Opinions Please
Has anyone given these mufflers a try?

Dimensions look good for a stock '73 rear suspension and a 383 installed with a 2.5" system.
Thanks much.

I just finished putting Borla Pro XS on my 78, after having Dynomax Ultra Flos that had rotted out. They sound similar. The Pro XS mufflers were felt a bit lighter too.
