Continuously innovating and progressing forward.the GTC(EV Control)and GTS (Ultimate Performance) were introduced, ultimately taking the place of the HP through GT2 for all newer model vehicles. The GTC, utilizing electronic valve technology to controlsound, back pressure. andoverall performance. became a single combined solution. enveloping everything from OEM all the way to GT2, a complete spectrum of sound and performance into one unit by the use of our electronically controlled variable.

GTC (EV Control) Utiizing our E.C.V.C (Electronically Controlled Variable Chamber) technology, the Meisterschaft GTC uses an electronic valve system to control the volume and tone of the exhaust system at the users will. In the fully open position, the Meisterschaft GTC provides the most exotic. aggressive exhaust note similar to conventional GT2 systems we have offered. When in the closed position the GTC system will produce a sound comparable to OEM. The Meisterschaft GTC provides the best of both worlds. Recently, vehicle manufacturers have begun to include valve-controlled exhaust systems right off the production line,which are adjustable via a button on the dashboard, or even within driver mode selections (Comfort, Sport, etc.). To accommodate the current trends, our exhaust systems for these vehicles are now designed with specialty components. allowing a plug and play replacement that retains the use of OEM sport exhaust functions (whether they are vacuum-solenoid controlled or electronic motor controlled). As such. customers can still enjoy and benefit being able to use the OE switch to control our exciting GTHAUS exhaust products.

  • Sound level 8/10 (Aggressive)
  • OEM Exhaust Sound level being 2/10

Depending on the vehicle application, several different tip styles are offered to suit each customer's individual taste. Optional finishes are also available for further customization.

Meisterschaft, MUSA, and American Roar Racing exhaust systems provide the most unique exhaust notes in the industry, period. Our exhaust systems are custom tailored for each specific vehicle without the use of any universal parts.

    Nice bundle and great customer service
    Size: Saros 10R/Qrevo CurvX/Edge 2 Accessories
    I purchased this as an economical bundle for my Roborock Qrevo Curv. All of the parts seem to work and fit properly, which is good since I have actually had problems with the main brushes from a different maker. The only issue I ran into was that the Roborock website seemed to indicate that all of the Qrevo Curv models use the same filter size. Apparently the CurvX/Curv 2 Pro use a different filter. When I asked VIEWALL about it through Amazon messaging, they were kind enough to let me know about the difference and even offered to send me filters for my model. So you can count on excellent customer service from the company.

    Affordable Roborock Qrevo CurvX Accessories That Fit Well
    Size: Saros 10R/Qrevo CurvX/Edge 2 Accessories, Size: Saros 10R/Qrevo CurvX/Edge 2 Accessories
    I have a Roborock Qrevo CurvX vacuum cleaner, so when I saw this replacement parts pack, I wanted to give it a try. The box contained everything needed to carry out the maintenance schedule recommended in the Roborock app. It even included a small screwdriver, which made changing the side brush easy — a thoughtful extra touch. I compared all of the replacement parts to the original ones and didn’t notice any major differences. Overall, the parts do seem slightly lower in quality than the originals, but not to the extent that I think it will significantly affect performance or durability. I replaced the side brush without any issues, and it fit properly. The mop pads were softer and fluffier than the originals and didn’t fit quite as snugly, although I don’t think this will have much impact on cleaning performance. The new filter installed perfectly, and the vacuum bags also fit as expected. Overall, I’m happy with this product. It’s reasonably priced and represents good value for money. I can see myself continuing to use these replacement parts in the future. I’m taking one star off due to the parts being of slightly lower quality

    Value replacements
    Size: Saros 10R/Qrevo CurvX/Edge 2 Accessories
    As far as I can tell these are pretty solid replacements for the SAROS 10R. My original side brush was all torn up after just a few months of use so I found these replacement parts. Haven’t used the mop pads yet, but they are a similar design to the “upgraded” mop pads offered by Roborock which are superior to the standard one IMO. Everything else seems to be equal quality to the OEM parts, and at less than $12 I have no complaints on this kit.

    Filter does not fit my Qrevo Arc. Photo shows size comparison between my old (very dirty) filter and the replacement filter.

    Solid replacement parts kit — just skip the mop pads
    Size: Saros 10R/Qrevo CurvX/Edge 2 Accessories, Size: Saros 10R/Qrevo CurvX/Edge 2 Accessories
    This kit has been a handy all-in-one refresh for my robot vacuum. The main brush, side brushes, filters, and dust bags all fit correctly on my Qrevo, slid in without fuss, and have been performing on par with the originals — suction feels unchanged, the side brushes kick debris toward the intake properly, and the filters look and seat identically to the ones they replaced. My one real complaint is the mop pads. They're noticeably thinner and flimsier than the OEM pads, don't hold water as well during a run, and left streakier lines on my floors compared to what I'm used to. I've ended up going back to the original-brand mop cloths and just using this kit for the dry-cleaning parts, which have genuinely been a good value. Four stars — great kit minus the mops.
