I need a pair, left and right factory exhaust manifolds. Prefer the DFW area to save shipping.
If you have them off take a good look at the burn marks.. There is almost .5 of an inch that is blocking exhaust flow.. Not only that but the casting has HUGE intrusions that disturb flow. Stick your finger in there and feel around. That is the same reason we buy CAI's.. To get a smoother flow of air. I personally like the stock look and have built quite the sleeper when looking under the hood.. For me anything helps.. After seeing the manifolds off and knowing their going back on, there was no way I was going to put them back on without porting them.I don't buy that....I've heard of plenty of people buying the shorty headers (for trucks)and not picking up anything....period. And the shorty headers look a ton better than the stock castings.
