Hey I just want to know something, I have 02 v6 with duals on it into glasspacks so it looks like because I didnt put them on, but anyways I am thinking about either flowmaster 40 series or the single chamber ones. I want to leave the cats on, but if i have to take them off i will. I just dont want a dumb sound. Thanks.

 

I'm not a fan of Flows, but they do make a decent sound for sixers, I think you'll be satisfied with them, most people are.

 

no cat mid pipe makes the sound soooo much better but yeah most people like flows, but personally i got the pypes off road kit for my 97 and i love it, idk about your gen on the pypes but my friend has flows on his 03 and it sounds really good, he also went true dual though

 

If you are looking for sound, flowmaster is sufficient...
