Nice, also a perfect fit using the size code chart. You will not be disappointed. Bought them on sale with free shipping so price wise your on your own.

I bought the s40's thinking that it was near the lowest #= deepest sound as higher the model number the quieter it is, however 40 then 44 the 10 in order. I took off the resonator on my 2012 chevy impala and it sounds like a v8, with Injenr X-1017-BB - EA Nanofiber Dry Air Filter /or K&N (oil based cotton,, this thing growls an flow mor air. I do get a power kick out of it and not to obnoxious unless im "getting on it"! super40 with resonator sounded almost like stock,for me this is Grrreat!

Overall it was a good Moffle ,but I change it for Flowmaster dbx in my opinion it is better moffle the sound is so much better,like music to my ears ,if you want a good muffle Flowmaster DBX you will be very happy. I have the 3" inlet, 3" outlet and it is awesome!!!!!
