Crown Automotive Head Pipe with Catalytic Converter Reviews
I only give this four stars instead of three because it was: 1) Easy to attach 2)Threw no check engine lights 3) Has very good welds. However I could not give it five stars for one reason. The part where the tube goes around the engine oil pan from driver to passenger side is angled funny. Mine hangs below the oil pan. Had to tak it to a muffler shop to button everything up.
The product is what it says it is however, in my experience the product is poorly made.
The piping after the catalyic converter is the exact same as the stock piping and aftermarket cat back exhaust system for the muffler input causing me to have to cut and expand and contract both parts, also it was off slightly at an angle pointing downward. Once I got everything to somewhat work after two and a half months the hangar support broke at the weld.
All parts were installed on a 1999 Wrangler Sport 4.0L with an MBRP Stainless Steel Cat back system.
