well , I was just curious what does the stock muffler sound like when compared to the aftermarket ones ---flomaster , dynomax , magnaflow , hooker ect. I have not modified the cat-back , yet so any info would be nice . I have the slp 1-5/8 stainless steel headers and "gutted" random tech stailess steal cat . Also , what happens if I go to the 3 inch intermediate exaust with dual 3 outlets ? Will it be louder ? please help here . How bad is the stock muffler/catback anyway ?

 

I picked up .2 in the quarter from just the catback. I used the Hooker catback, and love the sound,
