Bettt!! I'd love to hear it! I ended up getting Ford Performance Extreme but I'm still curious on how the other ones sound likeI just ordered the MBRP Race Cat-back for my 24' grabber blue ecoboost. I soon as I get it and installed I will post itI just might be the first one with it. MBRP has nothing online for 24'-25' and I scoured YouTube to find anything with no luck. just the S550's.
