So, that being said....now i'm looking into a cat back again. What are some of the better known ones for the G37X SEDAN? I'm looking for somethinng not too loud especially at idle. I like a lower tone exhaust, and good performance. I would like to keep it at around $1000.00 or less if possible. I'm not seeing a lot to choose from for the G37X sedan. I see Stillen has one for just under $1000.00
