Why You Want This

Many customers experience a burning oil problem or blue smoke coming from their exhaust after installing aftermarket J-Pipes or turbo back exhaust systems. Installing these parts causes a change in exhaust pressure, allowing engine oil to escape out the turbo seals. This leaks into the exhaust creating the burning oil smell and blue smoke that many people see. Cars with catless J-Pipe setups experience this issue much more than cars with high-flow cats.
