New at Summit Racing: MagnaFlow Rockcrawler Exhaust Kits for Jeep Wrangler JK

  • thumbnail

Systems that provide clearance and durability for serious off-roading.

What They Are: MagnaFlow Exhaust Kits

Why They’re Cool: An excellent power upgrade without compromising off-road capabilities. The Rockcrawler systems feature a high-clearance design that won’t get bashed up on your favorite trail. They are designed for Jeeps fitted with aftermarket components, like metal bumpers.

Using mandrel-bent stainless steel tubing, the kits are dyno-proven to produce more power than the stock setup and are durable enough to face the rigors of trail driving. The system exits through the driver’s side via a single stainless steel muffler, producing a deep, aggressive exhaust note.

All necessary installation hardware is included.
