i was wondering if i could get the pipe diameters for a stock 96 4.6 tbird...

i need to know the before first cats, between first cats and third cat, and from third cat back to mufflers

I want to know what other people have done as far as switching to high flow cats. what brand did you go with and how did you set them up.

Here is my plan... i want to go with a set of high flows cats, gut the third cat and finish it all up with a set of flowmaster 40s.... please give me some input!!!!

Thanks!!!!!!!!!!!!!!!

you can go catless as long as you a) get a tune to turn off the rear o2's, or b) get mil eliminators.

oh and hit up the search button there is a ton of info about this.

oh oh, check out the sticky with the exhaust clips.
