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 Injen%XAE 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!

Was told it was an exact fit. No cutting or welding. NOT! Shop had to put two extensions in and weld them. I am still very satisfied with the muffler. Probably cheaper going this way than buying the one that is an exact fit.
