convertion kit

does anyone know where i can find a convertion kiy for my 2000 3.8 camaro. and also what would be better a flowmaster or a loudmouth  

i think magnaflow is best for the 3.8s. not sure htough

Conversion kit?

if by conversion kit you mean to get an exhaust system made for the LS1 V8 to fit the 3.8 then you just buy the exhaust system and the kit... like usually whereever you can order the SLP it comes with options to fit a 93-95 LT1, a 96-97LT1, or a 98-2002 V6...
 
otherwise idk
 
and i personally dont like flowmasters, but i have an Lt1... so it will sound different..

i second that notion..flows sound like garbage
