stock pipe

what is the stock pipe width on a 94 sentra

1.5 ............1.25 maybe?

thnx

check the width on aftermarket pipes made to get your general idea just in case your going custom, if its still your 1.6 litre id go no bigger than 2.5....... probably would recommend 2.25

i wouldnt even recommend that. id say 2 inch is gooe enough. otherwise it'll sound like the civics around me that ae always farting....(insert fugiot joke here)

2 is good
i got about 7-10hp out of my 1.6
