OK, enuf already...
Regarding Hookers:
MaxFlows (MFs) flow more than AeroChambers (ACs) which flow more than Super Competitions (Turbo ?)(SCs). I did see the flow numbers once upon a time but don't remember (or really care) for now.SCs will drone more than ACs and MFs will likely drone more than AC's also. SCs are not black--ACs are black. I don't know much "personal info" re: MFers...
I have the Hooker SCs because my system is so old that SCs were furnished as standard on their 2.5" dual systems"back then"...I believe ACs are now std w/ their 2.5" dual system and are hard to beat. You can talk to "them" re: upgrading ACs to MFers in "todays dual system"...
Many have degraded the Super Comps as junk/ trash/ garbage/ whatever--but I can't justify replacing mufflers that just "keep on ticking"...and, I kinda like the tone & they're not too drony for me...
As many have said before, turbo powered vehicles do not need/like back-pressure. Just write-off that info source as a loss regarding TBs & TTAs.
