Review on Precision Parts Compatible 2011 2016 PP 421 B by George Marquez

This was in a 2016 lml. Before that I had a standard tube with resonator removal plate and PCV redirection. Now the online applications are as follows. Small power increase, louder turbo whine and lower EGT. As for the power gain, I haven't measured it on the dyno, so I can't say if it's increased. It's obviously going to sound a lot smoother, so there's probably going to be a bit more added, but it's not enough for anyone to really notice. Now for the turbo whistle, it sounds the same to me. Maybe because I've already removed the resonator? Now for egt, I think it's gone down a bit, but not by much. I saw a much bigger difference when I replaced my downspout. Was it worth the money to replace this part? Maybe not. It looks a lot better to me and I'm sure putting it on will help. It's already there, so I'll leave it. The reason I didn't give 5 stars is precisely that. The drain tube has an o-ring but this one doesn't. You can't even use a standard O-ring with this tube. It would be nice if this new tube had a groove for a standard O-ring.
