This pipe is as advertised. It does what they say it will do. The quality is great. It fits perfect. The boots are sturdy. The powder coating is flawless. I've said on some other parts I've reviewed that I can't find anything wrong with the powder coating. This pipe was no exception to that. After getting it all hooked up, I have absolutely no boost leaks. WCFab makes great stuff.

I had purchase 2 other pipes from SD and the fit was terrible, boost leaks and install took 3 hours. But when I bought this one from WCFab, I had the pipe in my truck in about 45 mins and the fit was perfect with no leaks.

I had another brand pipe already on the truck. Fitment was terrible and boots sucked. Finally replaced it with wehrli fab piece. Everything I've bought from these guys has been top notch. Build quality, fitment and powder coating is awesome. Great customer service if I call with questions. I will continue to buy and upgrade parts from wehrli and recommend them to anyone I can. Thanks wehrli fab
