Jeep moved the exhaust forward on the 2012 Wrangler. Unfortunately, on Jeeps with 2.5-Inches or more of suspension lift that means their front driveshaft is liable to make contact with the exhaust y-pipe, melting the CV Boot and causing the driveshaft to fail prematurely. This exhaust spacer kit from Outland automotive fits 3.6L equipped Wrangler models, helping move the y-pipe further back and increases the amount of front suspension travel from 2.5 to over 5.5, thus saving your driveshaft. The spacers install on the flanges between the front Headers and y-pipe.. the great thing is the kit is easy to install and does not require permanent modification to the exhaust. Hardware included.
