The factory catalytic converter is mounted directly behind the turbocharger, while the CTS Turbo pipe is designed for straightforward installation in its place.<\/p>\n<p>It is made from 3-inch T304 stainless steel pipes with smooth mandrel-bent bends. It has two O2 sensor ports and the option to add a third port. The almost 4\u2033 expansion then tapers down to 3\u2033, allowing the best possible flow as exhaust gases pass from the turbocharger to the catalytic converter.<\/p>\n<p>The pipe is hand TIG-welded and provides an upgrade for improved exhaust gas flow, increased performance and a more pronounced exhaust note.<\/p>\n<h3>Product details<\/h3>\n<ul>\n<li>Made from T304 stainless steel<\/li>\n<li>Mandrel-bent stainless steel pipes<\/li>\n<li>Fully TIG-welded construction<\/li>\n<li>Option for a third O2 sensor port<\/li>\n<li>Fitting hardware included<\/li>\n<li>Weight: 4.54 kg<\/li>\n<\/ul>\n<p>To eliminate the engine warning light (CEL), which may appear after installation, suitable engine software adjustment is required.
