I sell kits aswell. And you dont have to grind down that section of the block down, can remove the turbo assembly without having to pull the engine, and can use Megan screamer pipe with screamer part cut off and Apexi SR downpipe if you decide you want to save some money and not have a custom elbow/DP made. And my subframe spacers are way more beefy then those on eBay
