Anyone (including my guy) will install a catless DP, they could care less you just have to deal with swapping back to stock for emissions or paying someone off to pass you.. If you have the proper equipment (good jack, jack stands and tools) it won't be hard you just need to take your time because if you break a bolt on the turbo your in trouble til you get a new bolt.. It's up to you but if you want the guys number let me know cause I'm sure he'll give you the beat deal you'll find. I asked about engine as well because I'm not sure my plug will fit your TSI im pretty sure raven6t9 makes 2 versions.. Look up his DIY and if it will fit like I said you can have it
