I have a 19 5.7 hemi and installed ARH long tube Headers
1-7/8 https://americanracingheaders.com/c...truck-2019-long-system?variant=19842422112310
along with Diablo Tune 180 Thermostat and a catch can and K&N filter. I feels a lot sluggish now I regrett spending this money. It was pulling pretty hard for a truck with stock manifolds. So, From 1000-3000 RPM feels like a V6 and starts to pull a little more around 5000-6500. I put a stock muffler back on it to create more back pressure, but not much changed. Any advise besides the $9000K supercharger option?
