Sanderson PowerCaps Under Chassis Adapters

Our PowerCaps capture hidden horsepower in under chassis exhaust connections. Under chassis adapters allow you to run a quiter under-chassis exhaust system.

PowerCaps eliminate turbulence and create a smooth flow of exhaust gasses into your underchassis exhaust system. Our PowerCaps adapters bolt directly to the blockoff plate flange on your Sanderson Lakes-Style Street Rod Headers, and make a dramatic difference in performance, reduction of exhaust gas temperatures, and enhance the exhaust tone.

NOTE: If your engine is making good power, this is a highy recommended item to prevent damage to your coated headers. More info is at this Knowledgebase article

Try them on your street rod, and get the extra horsepower out that's been lurking in your engine!

• Sold as a set (pair)
• Ceramic Coated
• Blockoff Plate sold separately

TIP: Whatever blockoff plate you use, it is removeable so you can bypass the exhaust system in venues that allow you to run open exhaust. You can create your own blockoff plate or use our "classic look" Finned Cast Billet Aluminum Plates (#LFBP), or use our Turnout Tip (#LFTO).
