Love the sound of my 40 series. I put it on my 99 Trans Am. Sounds great and turns heads. Love it.

So happy with the new sound and so is the wife. You most def can hear it - but never is it obnoxious - not even at WOT. Just a nice mellow tone from idle to 75mph and no drone - no chopper sound - Deleted flapper. No difference in V4 around town or on the highway.... One big plus - now I can hear it shift - which helps feel it shift - before I hardly knew when it shifted. . Towed up a long grade - no drone - just a nice throaty sound even working it.... Cold & warm starts sound great!
