they are all the same really, you want it to have 2.25 in and out let tubes.
if you have a fatory pipes you will need to have it welded in.
if you have after market pipes like i do, you can drop the exhaust and clamp it in, i also bought a flange to the cat and had one tube cut off and the flange welded on to it, so it would bolt up to the cat.
this is a 32 inch glass pack. my factory res was around 30 inches, (flange to tube end) so after cutting the tube off and adding the flange it fit pretty good.
