I don’t have any clips of sound, wish I did, I wasn’t even worried bout having them installed. Thinking they really wouldn’t make a difference, but since I had already purchased them I finally put them in after couple weeks of running without them with a tune, dp, cai and when I got my truck In my truck it sounded so much better I asked the guy if he messed with my exhaust while installing the adapters. I do think it gives enough of power gain you can feel but that could be just wanting to. I know for sure 100pct it makes it sound deeper and a lot better. It’s a must if you have tune or exhaust mods done. I just changed to mpt tune prx 94 tune today also from 5 star 93 and wow mpt tune is way faster than 5 stars. My truck is super fast and fun now. I don’t think I will do anything else to make it any faster from this point on. It will burn the tires up right now, and throttle response is super quick, I thought my 5 star tune was bad ass but this mpt tune is insane. Just hope I don’t blow my engine. Lol.. it’s definitely not a calm low power tune. It’s a haul ass and go tune. Which Is what I was hoping for. I actually see what the hype was about and the guy on here named (Guy) wasn’t lying or bullshitting at all. It’s awrsome from what I’ve seen so far. Whipple is probably the safest but Mpt has to be the most powerful.
