reason for question? just curious... because it doesn't really matter if you want to enlarge it unless you open up the inside as well... i can get a measurement for you in a little bit if no one responds before me
i have a set of ported braincoated manifolds and a set of stockers
if i get the ok from tbirdbrain, i'll post the numbers. there isn't much different in the outlet or the inlets...but the meat in the middle... i have no way of measuring runner diameter inside the manifold...but i know how much was taken out
for the record.. RobertP has brain coated super ported manifolds and 2.25" compression bent exhaust...and runs 11s
Oh, I'm not doubting the potential of the stock manifolds. In fact, I talked a guy out of spending $$$ on the jbas in favor of the stock; citing the guys running 11s with ported stockers. I'm trying to setup a group purchase for true dual exhaust for the local club, I just need to know what size would be the best to go with.
So I'm posting here because, well, most of the recommended headers you guys have listed here for 5.0 Birds are obsolete or no longer produced. I'm halfway through gathering parts for my GT40 build and the only roadblock I'm hitting is this.
Now that I got the correct cat forward exhaust assembly for the car, I have some options on the cat back exhaust. I have the option to replace the cat back exhaust and mufflers. The rear tube of the assembly below is just a reducer and has no muffler capabilities. As I learned with the two...
i just had my t bird dropped off at my house...looks nice just needs to be washed and waxed.
i was wondering..if i cut off the mufflers out back how much pipe or how long of a tip would i need to fit in place of them and what is the diameter of the stock pipes?
