Hi,Here is my problem,my jeep has a cracked exhaust manifold,the rest just fell off after the cat.Contemplating doing the job myself because if I pay someone I dont believe the truck is worth the money.First,is there a improved system I could install in close price to OEM equip,and second can I possibly get any tips or info on the BEST way to go about removing the old bolts,which Im sure will be a chore.I am confident I can do this and would love to keep this truck as it tows my 16' boat nicely.tThanks in advance for any help,Ernie
