Header/engine change question?
Hello, I've been looking to redo my entire exhaust system on my 99 WJ. Everywhere I look they say the header will fit grand cherokee's from 91-99 and that the part ins't compatible with 00 and newer style WJ's. Why would this be did they change something from 99 on up?
Any good exhaust systems you guys recommend? I will be redoing everything. Cat, sensors, everything.
