Notes

• A TCU Tune is HIGHLY Recommended and is available as an add-on.  DO NOT PURCHASE ANOTHER TCU TUNE FROM A 3RD PARTY ASSUMING IT WILL WORK CORRECTLY WITH THIS PACKAGE!
• Note we recommend a free flowing exhaust as the factory exhaust is restrictive and will reduce the performance of the kit. If you need an upgraded exhaust we offer a Dual 3" Exhaust solution as an add-on upgrade.
• Each component to the package can be viewed individually including the cost savings by purchasing the package.
