wassup everyone . I have a 93 GT and I currently have a 2.5 inch x-pipe and flowmaster weld in mufflers that were put on the car in the mid 90's before I owned the car. I don't know what kind of flowmasters they are, but I am considering getting the American Thunder cat back. I just want to know if my car will sound exactly the same with the American Thunders vs the Flowmaster weld in mufflers that are currently on it.

 

well, if they are 2-chambers...yes
if they are 3 chambers...no...it will be louder.

3 chambers are called force 2 i belive?

 

i have an AT catback with a upr x and i have a vid of me doing a flyby here on the site, just search for it

 

The more chambers the quieter the exhaust is. I.e., 1 chamber flows are much louder than 2 chamber flows.

 

The catback might make a lil difference, also might be worth a few pnies. If u have weld in flow right now and ur switching over the catback will be mandrel bent which will make a lil difference.
