About the only thing “crude” is the coolant crossover. The rest is nice. Is it 100% bolt on? No but neither is a $6k Hellion Turbo Kit. Sure, I plan to modify my kit a little but it is purely because of a look I have in my mind.
Speaking from experience, the castings were so rough and sharp they could cut you. The "powder coating" was paint that was applied with a brush. Parts also showed up damaged which the guy who runs tork tech said to just un-bend it and run it. The box had no damage, he just packed them poorly and all the parts clanked into each other in transit.
Like I said, will it work? yes. Is it a well made product? I'm not so sure...
