I have the pop charger on the roadster w/the nismo exhaust.I really liked the pop charger with the stock system,deep sound re:growl.My friend has the same set-upop/nismo exhaust.He says the exhaust will get deeper with more miles, 1000-1500.We shall see.TZ

 

I guess you are looking for a Chevy V8 sound verses a Ferarri V8 sound????

Yes, it is loud and a bit high pitched, but I think it depends on what you like, I am going nismo VS borla just for the sound (and finish) . Once I heard it I was sold. btw, I like ferarris

Yes, the JWT will make it a bit meaner sounding, esp at WOT, not necessarily deeper, but a bit more thoaty

 

I like mine alot more now then I did when I first got it. The tone did mellow and adding the JIC Y and JWT pop / Crawford plenum. This combo has made it perfect. You do need to give it some break in time for the tone to mellow a bit. My Stillen was the same.

 

Oh adding the JIC Y did take some of the drone I had out. I had a little.

 

Yup, not sure about it tho.

Nismo sounds pretty much like stock to me. You should try it out with the RT cats
