OEM Restriction

Factory C8 RS6 & RS7 downpipes include two large catalysts that restrict exhaust flow, limiting power output. Upgrading to ARM C8 RS6 & RS7 Downpipes eliminates this restriction, improving exhaust flow for increased performance.

CONSTRUCTION

Built from SS304 stainless steel, ARM C8 RS Downpipes ensure long-lasting strength and weld integrity. Starting at the turbochargers with a 5.75" CNC-machined V-Band flange, these downpipes seamlessly connect to OEM or upgraded turbos with the same exhaust housing size. A centering key in the V-Band guarantees perfect alignment with OEM or ARM C8 4.0T Midpipes.

The downpipes feature a full 304 Stainless Steel 5.5" body, tapering to 3" to connect with either ARM or OEM midpipes. For added convenience, the design incorporates a removable midpipe flange, significantly simplifying installation. This feature eliminates the hassle of securing hard-to-reach bolts, saving time and effort. Simply pre-install the midpipe flange, then attach the downpipe using a single, accessible exhaust clamp.

Exactly what I was looking for.
Color: Brown, Size: 3 Panel, Color: Brown, Size: 3 Panel
Although other reviews found this item was too lightweight and flimsy, frankly it was exactly what I was looking for. I needed to partition my workspace off from the rest of the room and I wanted something that I could easily attach to the back of an unfinished bookcase as part of creating a private space. It was perfect. Lightweight easy to handle and I didn't mind putting some nails through it. Great price point for what I needed.

Made cheaply.
Color: White, Size: 3 Panel
Seems fairly sturdy ( 3 panel white) but made with extremely cheap materials that will not last. The cheap materials are very noticeable with the white screen. No assembly needed. Would not but again.

Beautiful brown privacy screen!
Color: Brown, Size: 3 Panel, Color: Brown, Size: 3 Panel
Why did you pick this product vs others?: The measurements were perfect for what I was looking for.  The length and width are the same as my rattan raised garden bed which I have placed in front of the screen on the deck.  This secures the screen so there is no issue of weather conditions. I have been looking for weeks for a privacy screen at every possible product and combination. and almost gave up when I noticed the measurements of the screen would fit behind my raised bed!  Now I am going to plant some flowers in it.  This is a terrific buy for me.  i am so happy! Looks great: The perfect size, color, and design match my brown deck rattan furniture. Ease of assembly: No assembly which is nice in this hot weather! Room divider: It provides much needed privacy

Good coverage and size, looks nice and easy to use.
Color: Black, Size: 6 Panel
My son uses this to partially cover his window as he is in a high rise and people can look in. It is tall enough and wide enough to provide reasonable coverage and because it doesn't require putting it together, it is very handy to use immediately. Good value for the dollar and looks nice.
