aFe Twisted Steel Loop Relocation Pipe (48-48021) _Silicon Part # 827-537WB) for 1999-2005Scorpion Mild Steel Y Pipe Spacer Kit (48 90003) by aFe. Adding 2. 5" or more lift to your vehicle will change driveline and can create clearance problems between your driveshaft and factory exhaust. aFe's 304SS exhaust spacers are a great problem solver which moves the factory y pipe rearward to prevent contact between the driveshaft and exhaust during extended suspension travel. JK models with Long Arm lift kits will require increased clearance.
