i have 2016 impala new bodystyle 3.6l v6 whats the exhaust size after the cats? i wanting to put in a electric cut out cause i love my car quiet but would like option to be loud when wanted
I believe it is 2 inch but i could be wrong i say this because i had my mechanic measure the pipe diameter for me because i was looking at some magnaflow mufflers but it may be a different size after the cat.
