I love my obx's the hump doesn't bother me one bit, the fit and finish is great IMO.

 

Has anybody had any problems with the resonators? Im wondering how much they will quieten down the exhaust. LTs with no cats and a corsa are loud as hell and get a little rasp in them, Im wondering if the resonators cut the sound down as much as a set of real cats.

 

anyone know what size primaries these have?

 

they're 1 3/4" primaries with a 2.5" collector. I ran them and they had the same SOTP as the pacesetters.

 

I have the old hump ones and the hump doesn't bother me that much, but what I had to do to get them to fit past the front driveshaft isn't pretty. If I had some cash and found something that I'm sure would fit past the front driveshaft I would buy something else. They do seem to be a decent improvement over stock though.

As far as the resonators go I wouldn't count on them decreasing the sound much as they are just a straight through design with no baffles. I have a fair amount of drone with mine and a magnaflow catback, but I have gotten used to it and it doesn't bother me much anymore. Pic of the inside of one of the resonators on mine.

 

Wonder if the new design clear the front shaft any better, IIRC these worked on a lot of the SSS guys trucks and the driveshaft is in the same place

 

According to the item descriptions, those are for the 6.2 and the first ones listed are for all except the 6.2

 

why are there so many o2 bungs? seems like there is one extra, unless the nnbs trucks have more sensors...

 

Idk the reasoning for the extra bungs, but it sure made tuning with a wideband easier! I just made some "plugs" out of old bad sensors I had lying around...
