The team at Rvng is proud to announce our Rvng designed valved system for the G8X platform are now available. The G8X platform isn’t known to be one of the best sounding cars, we decided we wanted to make a setup that we felt was the best sounding and performing on the market.
After many tests this is the design we settled on
Our system has a 4.1” single midpipe paired with a built in x pipe that leads into the muffler. This setup in our opinion is the perfect sound combination. The is hands down the best midpipe for your G8X, it allows both turbos to flow into one pipe making the spool way louder aswell as giving your car a deeper less raspy tone. We included the built in x pipe to allow for a little bit of a more exotic tone. Pair these two together and you get the best sounding G8X exhaust on the market.

Our Titanium products do not carry a lifetime warranty unlike all our stainless products. Unfortunately, because of the material it is weaker than stainless steel and does not last the same amount of time. Stock tune and most OTS you will have 0 issue. But If you add a pop and bang tune on a titanium exhaust system you risk destroying your exhaust which we will not warranty.
