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.

Heavy duty, thick tote bag.
This is a pretty heavy duty canvas bag. It’s a little smaller than it looked in the ad, but it does seem very strong and put together and I think it is waterproof or water resistant so that’s useful. I can definitely see this for shopping or just like out running errands, it’s got two sets of straps are nice. You can wear it multiple ways. The quality is pretty good. Better than a lot of the bags that I’ve been getting these through Amazon.

Pretty nice little bag
Color: Black
Wasn’t sure if I would like the size of the bag as I was planning on using it as my everyday purse. Pleasantly surprised by how much can fit in it. Definitely good for travel as it will hold what you need. I would only say that the strap would benefit from having a wire in it to prevent people from just cutting it off. Other than that, it is a nice looking bag. Good size. Seems to be well put together and sturdy. Note if you are on the bigger size, the strap might not fit around you. I do have to have it fully extended to fit properly. But it is comfortable to wear and the wide strap doesn’t put too much pressure on my shoulder. I would buy again or at least from the same brand.

Can’t beat this purse/ bag
Color: Green
Nice, light weight and plenty of room for lots of stuff actually. Love the built-in card holders very convenient, durable, the locking features with the zippers, genius idea,and the green is so pretty if you’re looking for a smaller bag and everyday smaller bag that can hold all your crap (face it ladies we carry a lot of crap) this purse is absolutely beautiful and perfect. I’m actually thinking about getting one for all my work stuff instead of my backpack.

Perfect bag for everyday wear
Color: Black
This bag is perfect! It’s just the right size and not super bulky. I love all the pockets and the clip to lock it! I loved the black one so much I went back and bought it in green! It’ll be so perfect to use on our trip but also it’s a great everyday bag. It’s super light weight and comfortable to wear front or on the back.

Nice but strap is deforming
Color: Green
This little bag seems to be very well constructed and is the perfect size for travel fir me. PROS: - has zippered. pockets including one in the back - The interior is a light beige color so you can see inside easily - the zippered pockets open wide for easy access CONS: - I wish the zipper on the top (main) pocket was a double zipper. - The attached shoulder strap is thin with no reinforcement. The strap is becoming deformed (wrinkled, folded) after only a couple weeks of daily use. The US no way to replace it as it is sewn into the top Overall it is a nice bag but I will look to replace it soon as a daily user because the strap issue
