What size is this downpipe?

obriennathaniel · 02-20-2017, 08:28 PM

I have a spare ER catless downpipe that I need to sell, just don't know what size it is. Can y'all help me out? I never measured any of my previous downpipes and I'd hate to have to pull out my current downpipe just to check lol it looks to me like a 4" but I'm not sure.

3"

Pretty sure on your PWG car it's considered a 3.5". EWG are 4".

F30 n55 RWD. I have a buyer already if it's a 3.5"

obriennathaniel · 02-21-2017, 09:11 AM

There is no 3". They only made a 3.5" and the current 4"

lol that's the thing, it wasn't really for my specific car. And I can't get an exact 3.5" measurement off of it but I can get a 4" measurement, but usually the O.D of the pipe is where the measurement comes from, not the flange.

I got it from ER but they're terrible at replying to emails so I had to resort to measurements and the forums. I'm aware of the specific years and sizes. Guess I'll try emailing them again.

Jeff@TopGearSolutions · 02-21-2017, 05:47 PM

Manufacturing date of 7/13 or later are the 4". Everything earlier is 3.5".
