Our premium catback exhaust system is a full length T304 stainless steel exhaust system that's sure to turn heads! Cast flanges make a smooth transition from the factory turbo catalyst pipes into our downpipes and upgrade the size of the piping to 3". High quality brushed T304 stainless steel adorns the system with TIG welding throughout. The piping is as straight and smooth as possible, with mandrel bends and minimal mufflers for maximum flow. Quad pipes exit the system into the exhaust tips and consist of dual 3" valved exhaust paths and dual 2.5" non-valued paths. This allows for multiple sound profiles depending on driving style. The RS Q8 is a monster and sounds absolutely menacing when under wide pen throttle. When the vales open, the fire-breathing twin-turbo V8 gets rowdy. Expect a deep and throaty roar that will send shivers up and done your spine as you're pinned to the back of your seat. And yet when you contain the beat and drive like a normal human being the ECU controlled valves close, reducing sound volume and drone. If you fight the urge to drive like a maniac, the exhaust will reward you with a pleasant low rumble that lets you know its there without upsetting the neighborhood. This is the ultimate exhaust system for the Audi RS Q8!

Features:

  • T304 stainless-steel construction
  • Full system from the cats back
  • Argon back-purged TIG welding throughout
  • Dual 3” mandrel-bent brushed tubing with dual 3” valved and dual 2.5” non-valved outlets
  • Ultra smooth Cast downpipe inlets
  • Dual exhaust valves
  • Brushed-finished sound absorption mufflers
  • Rugged and precise mounting brackets
  • OEM style no-compromise flex sections that won’t collapse, billow, and fail
  • OEM style slip clamps
  • Plug and play design
  • Larger diameter piping compared to stock
  • In-house design with world-class manufacturing and quality control
  • Easy to install

    The factory exhaust system uses a complex array of hydroformed piping that has a maximum diameter of 2.75” and reduces below this in various areas. Various mufflers and resonators disrupt exhaust flow to tame sound levels. It’s not ideal.


    Our system uses all high quality materials such as T304 stainless steel, which is mandrel bent and TIG welded. All brackets are precise and high quality to resist sagging and make install simple. The system starts right at the factory catalysts. Cast inlets feed into the 3” piping, which extends all the way out of the 3” valved path. It’s as smooth and straight through as possible with only a single straight through muffler on each cylinder bank. During normal cruise, the valves close and switch to a dual 2.5” pipe to limit volume and drone.



    MUFFLERS

    The mufflers are responsible for tuning the exhaust note and do so without adding unnecessary restrictions to the system. Each unit features a straight-through perforated tube that’s tightly wrapped with stainless steel and fiberglass material. The mufflers have a beautiful brushed finish.

    EXHAUST VALVES

    Our system features two valves that allow control of the volume of the system via the factory exhaust valve actuators. In doing so, the system can go from tame to aggressive instantly! Unlike pneumatic systems, and other common valves found in the market today, our system maintains identical OEM operation all the way down to the factory valve actuation angles. We cast the valve housings out of T304 stainless-steel. Internally the system uses CNC-machined T303 components and bronze bushings, which have stood up to our extreme torture testing. All necessary hardware is welded into place and is designed to combat heat and vibration for years to come.

    BRACKETS

    Our brackets ensure a strong and precise fit, every time. With our design, you’ll never need to worry about the brackets sagging and losing their shape over time, or the post slipping out of the hangers. The brackets are rigid, exact in their position, fit snugly in place and are made to stand the test of time.

    CASTING, TUBING, AND WELDS

    We use T304 stainless steel tubing throughout. We brush and de-burr all pipes, use mandrel bending techniques to ensure the pipes keep a constant diameter throughout, and use argon-back purged TIG welding for a strong and attractive weld. The downpipes use cast adapter for an ultra-smooth transition into the system.

    FLEX SECTION

    We use an OEM-style flex section that’s fully sealed with a corrugated inner lining. This improves flow and resists issues that cause other styles to collapse, billow, and fail.

    CLAMPS

    Our system uses OEM-style low-profile slip clamp. Our clamp selection allows the system to sit high in the exhaust. Each connection point is strategically placed to ensure the system has minimal opportunity to rotate during install or during years of heavy driving. There’s no cutting, welding, or glaring compatibility issues no matter the scenario. Just Plug and Play!  

    COMPATIBILITY

    We’ve designed our system to be 100% bolt-on. There’s no cutting, welding, or finagling to get the system to fit. It simply bolts on for use with the factory turbocharger catalyst pipes with all hardware included.

LOL.. true story.

Great scent, but leaves a film on my skin.
I was expecting bars of soap with more of a peppermint/eucalyptus fragrance and I just could not relate those fragrances to what the soap actually smells like. The Viking Revolution soap doesn't smell bad per se, and actually for me is rather fragrance neutral like you might find with the more sterile hospital and clinic type soaps. The lather factor for the Viking Revolution soap is mild to moderate in our hard water. It doesn't overdo lathering up but does lather up enough to let you know it is soap and is rather pleasing when rinsing it off where with some soaps you rinse and rinse and still need to rinse more to get the lather off your skin. I wash my hands and face many times throughout the day and night and so far the Viking Revolution soap has done a great job in leaving me feel a bit more refreshed and clean. I have noticed a bit of moisturizing of my face and hands being much softer after use, so the Viking Revolution soap does seem to come through with that feature. I handle and am around livestock and animals quite often and did notice that the soap seemed to cut through the grime pretty easily. I haven't tried the Viking Revolution as a body wash type soap. The square bars are just about a perfect fit for my hand and are easy to hold onto. I will use one bar for the shower and keep the bar in a drip rack where it has a chance to dry out after use. I do really like the presentation of the soap itself and it's a nice touch that each bar comes individually wrapped and includes a sticker and a small card. A rather attractive package if you are giving it for a gift. I'm more favorable of recommending this soap than not recommending it. The only reason I am giving 4 stars is for the fragrances not really being detectable as peppermint and eucalyptus.I do think I would buy this soap again though, fragrance or not.

Awesome soap!
I love this soap. It was a little small, ut was great quality. If smelled good and did not break me out. I have very sensitive skin and this was very gentle on my skin. I usually use caswell and Massey soap and this soap is every bit as good as my normal c&m soap. Very good soap. I Will definitely will buy again.

Scent is too perfumey
This soap pack is ok for the price, but the bars don't lather very well. They do have a good level of moisturizer that doesn't feel too oily, but my big complaint is the scents. The black one is ok, but the others are like cheap perfume. And I mean CHEAP perfume. It actually hurts my nose. I have used higher end soaps with a beautiful scent that is subtle and natural. This is not that. Overall not a bad product for the price, but don't expect to smell like a $1 perfume. Yuck
