looking for a quiet exhaust
 

Hi
hoping you folks can make some recommendations for me. I have a 07 2lt 2.4with 18,000miles. I just installed a gmpp cold air intake and am interested in a performance exhaust. I am leaning to gmpp but i want Quiet. I had a 37 dodge street rod that was loud and i liked it but long drives kind of blew. Anyone care to offer and opinion on who makes the most quiet performance exhaust?

Thanks
