Just ran into the same problem while trying to install @
irxproductions exhaust.
Not only did the bolts that connect the Manzo front pipe to the stock overpipe not fit, the exhaust section was touching the rear suspension! Also, the rear tips were crosseyed in the exhaust openings. Had to remove it and I think it will be going back as defective.
OEM bolt won't fit through Manzo front pipe.
Manzo-supplied bolts will not fit through OEM overpipe
Dug around and found some bolts in a drawer that would fit.
Cross-eyed tips look ridiculous
