This one is 2.5" diameter, I saw the thread where the guy had the downpipe and 2.75". For some reason I can't play the sound though.
From what I have heard from other people is that because it is a thinner walled steel and made cheaper that it gives a louder and cheaper sound. That was the full midpipe and catback though. Just the catback or just the midpipe might be different and ok. Hopefully someone with expirience will help further.

i'm well hated for not posting a video of my tsudo exhaust but its w.e. Anyways i love them. for the price i get the sound i want. good power pick up, great note and its quiet at idle but can get throaty at a good RPM. it does need new bolts with it and a hanger welded on but heck 380 all in for a header back you seriously can not beat. I would recommend to anyone. as long as they don't live up north with salty roads
