Hey Guys,

I want to know your advice when comparing these brands:

Boost Logic 6''
Switzer 6''
TPC/Proto 5''
AMS ALPHA 5.5''

I've heard good things about each brand so now I am looking for the best option that people have experienced.

Thanks guys,

Nasser

 

Not sure what you are asking here? 6" 5"? New 991 turbo mods??
