Hi all, I was just looking at the exhaust system on my KJ AWD compared to my KL FWD and I noticed on the AWD all the areas where the exhaust is join its welded, the Cat, the rear muffler etc whereas on the KL FWD the areas where different sections join its bolted together, I wanted to take the cat off the AWD and check it but noticed I can't as its all welded up, is this normal that on the AWD all the joints are welded and not bolted together? cheers
