The Invidia Divorced Wastegate downpipe is VERY well made. 304 Stainless Steel, quality welds, and a price to be beat make this IMO the best downpipe you can buy when on a budget (like most people are). It is 3 inches all the way through which makes it perfect for someone looking into starting a 3inch turbo back setup and the divorced wastegate setup will separate the exhaust gas exiting the downpipe, creating a smoother exhaust flow which results in a few extra HP and TQ which is something enthusiasts will never say no to. The gains for a sub $300 downpipe are incredible. It's not arguable that this is the best and FIRST performance mod anyone should do to their Wrex. It's obvious that Invidia is very passionate about their products and that they will always deliver the highest quality parts to us enthusiasts whether you are on a budget or just care about having the best products out there. Invidia covers both ends of that spectrum very well!
The DEI Titanium heat wrap is now my go to heat wrap after this experience in using it. No wetting the surface first, no fiberglass cutting your hands, and being as malleable as cloth makes for an extremely simple and easy process of wrapping anything you need to. Just wrap and place a hose clamp to lock it down. According to the manufacturer, wrapping your headers and exhaust will reduce under hood temperatures by up to 50%. Under hood temps is something I'm always looking to direct away from parts like my airbox and TMIC and this product helped immensely in that goal. For $55 this is a great investment in increasing power output and the life of parts in your engine bay.
The Perrin turbo heat shield is sexxxy and looks fantastic and performs very well. I ran the engine without the heat shield for comparison and the intercooler got pretty darn hot. Installed this and even when the car is sitting in place I can always place my hand on the intercooler. This heat shield does a much better job than the stock heat shield and I would definitely recommend it for looks and performance.
