Stainless power headers fix excellent. Sound great with active exhaust

Installed the downpipes. Driver side fit well however, passenger side elbow sits lower which is a struggle for the midpipes. Midpipes have exhaust leak now. Debating on putting back to oem downpipes. The drone in cabin is a nightmare to say the least. Increased power yes but drove like crap for at least a couple days until computer could calibrate to new air/fuel flows. Gas mileage up a slight but but once you get a little power down, you're going to be filling up alot and I mean alot more often. Is it worth it? Maybe for someone that doesn't have it for a daily driver? Toy be the judge but for me, I spent a good 700 or so on these and now kinda regretting it. For me, since the 2025 doesn't have a tune out as of right now, upgrade the cai, differential bolt and brace and an upgraded exhaust. Downpipes right now is obnoxious loud and doesn't do your vehicle too much good without it. I liked and learned and spent money for install and now going to spend more time and money switching back to oem.

Lethal added an SPD product I wanted that wasn't on their website (stainless Catted Y-pipe for F150) so I could purchase it from them. Shipped within the timeframe they said it would and arrived in great shape.
