Why do I need to upgrade to a catted mid pipe?

When installed with your OEM downpipes, this catted mid pipe allows you to remain emissions compliant and still gain flow and performance

Why buy Alpha Catted Mid Pipe?

The Alpha Performance mid pipe was designed to not only increase performance, but was aldo designed to LAST.  This mid pipe features a 100% stainless steel construction with precision tig welds and no turbulence flex sections.  Spend the money once, and buy the best!

What should I expect with an Alpha Catted mid pipe?

As a basic FBO (full bolt on item), you’ll expect increased exhaust flow, with no restriction.  You’ll notice a deeper throatier exhaust note.  You’ll be ready to crank up the boost with additional mods!

What other modifications will I need?

You’ll absolutely want to purchase and install a custom tuning tool such as Cobb or EcuTek.  Your factory computer will require re calibration to run larger diameter exhaust safely and effectively.  Please contact us and/or check out our additional products and service
