They are already a slip fit design to them...one tube fits in the other, like the SLPs....if that's what your referring to on slip fit? Lol. Or are you saying there is another pipe, or? Confused on that part....I searched a bit before replying...I see most people saying they just use a crapload of copper RTV and a band clamp on all the joints...and on the front header to crossover copper RTV the crap out of the donut gasket and bolt together....hope im on the right track?
As far as figuring out if theyre OBX or pacesetter...i wish there was a way...they have the same collector size and primary size...so thats out for figuring it out I guess...any other ideas?
