This manifolds an up pipe are very nicely designed. An I have notice a 200-300 deg drop in EGTs turbo spools a lot faster an it gave the truck a deeper sounds to it. Ok now for the best information about this kit. Be ready for the biggest headache installing the driver side manifold bolts it's a super tight fit! It's almost better to pull the engine. I had the hardest time torque the bolts. All in all it's a great kit but have fun with the installation.
watch out if lmm
