No it doesn't. It is not the second pic I posted . This has one resonator and one muffler. Read first post.

I cant view that video since im at work, but thanks for posting up. Will check out when I get home.

Do you guys think there is any real rigidity loss when removing that little rear diff brace? I'm sure its a little, but can one make up for it with other braces/roll bar? Hmm.

Also, in for verification of 2 3/8 size measurement. Is this pipe measure in ID or OD?

If it is truely close to 2.5" and you dont lose too much rigidity, seems like a good deal still.

Yes, engineers put it there for a reason. You probably wouldn't notice it that much if you just drive it to and from work. However, if you did more spirited roads I'm sure the rear would feel different compared to having the brace on.

On the exhaust, it doesn't sound that bad.

But holy fak this thing is loud. It's just a really really low sound, and there is no muffling going on here. It's just two resonators.

Is there an O2 sensor on the exhaust it self?
