Well i bought this car about 3 years ago andthe mods are below..my car is in storage and honestly i dont know what size my flowmaster exhaust is..i have the receipt from when the previous owner had and what the part number says is......AM thunder f 2 cat 95-97..i have no idea what size that is..the reason im making this post is bc im buying an electric cut out real soon and i want to order it b4 i bring my car out..any help would be appreciated thanks

 

all the flowmaster catbacks they make for the v8s will be 3" pipe

so that is the size cutout you want....

it's either the "american thunder" or the "force II"

 

Yep, my American Thunder catback is 3" intermidiate pipe.

 

so when i call i want to order a 3'' cut out??...btw how do i know whether i need dual or single..i see u can order diff cutouts one thats 170 and 2 that are 390 like alll together or somethin like that..i have a y pipe if that helps? is that for true duals?

 

You'll only need one.
