Which 40 series?

[Tx01Muscle]

I have an '01 GT but I want to change out the mufflers. My question is which part number 40 series should I get? The 42541, or the 42543? What is the difference? Thanks.

42521 is offset input/center output
42543 is offset input/offset output

you want the second one #42543 offset/offset

ACTUALLY! I think the stock exhaust is 2.25 so if you want it the same size then get #42443 (2.25 dia.) otherwise you can get #42543 (2.5 diameter)

they are both offset/offset
