Conversion Engines in Jeeps

Some of the best engine conversions in Jeeps feature proper headers in lieu of factory manifolds. Top reasons for their installation include:

• Clearances within the engine bay
• Improved secondary exhaust circuit routing
• Better engine placement possibilities
• Increased engine performance
• Decreased underhood temperatures (in the case of coated headers)

In some cases, headers are simply a necessity with certain engines in certain Jeeps.
