Hi,
Checking to see if there would be a difference from going from dual glasspacks to dual chambered mufflers? I currently have 26” magnaflow glasspacks that have my exhaust a pretty much straight through exhaust (no cats/resonators). I want to throw in two flowmaster super 44s that I have sitting in my shed. Will there be any difference in Preformance? I know sound will change, that I welcome with open arms. I wanted to throw these on when my cam is installed.

IMO the difference in backpressure going from glasspaks to chambered would be minimal.
The sound more than anything will change.

You won't see any performance loss with that swap.
