i have a few questions before i put it on,

does the Flowmaster American Thunder route in the same place the stock pipes do?

will i have to jack up the engine to put the edelbrock 3" headers on, if so, how do i.

how can i plug the hole in the cat and headers for the AIR system

how much should i tourque the bold that attach the headers, anything special?

is there any special things i need to get or do, so i dont have to get a ride to the parts store in the middle of the install

Edelbrock TES headers 3" out/flowmaster American thunder 3" exaust/Catco HighFlow catco cat

 

well i basically have the same exhaust sytem as u, when i installed the edelbrock i need a lift(litteraly) i used my friends lift in his shop, The catco converter is a bit smaller than stock so ur flomaster will be about 11 inches short, so i got 11 inches in length of 3 inch tubing from a local parts store, welded it up and looks great, if ur gonna install the headers u might wanna use jackstand on the car to get under there to bolt on the Y pipe, took me 3 hours good luck, plus i took pics ill post it tomorrow so u get a better look
