Very pleased with to sound as well as the slight performance improvement that this muffler acheived. I install a shield above muffler to prevent exessive noise as well as heat entering cab of truck.

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!
