    Guys,

    I'm looking for a pair of fully gutted cats in excellent condition for a 355. Anyone have them?

    I have some hyperflows I'll be selling, they're still on the car though and probably won't be off until the spring.

    Yes. I have these. Brand-new, never been installed. Exact fit for F355, including new nuts and bolts. All correct fittings/bungs for installation of thermocouple/O2 sensors for each unit. Basically same shape and size as cats but with no catalytic material in them. $400.00 buys 'em.

    Thanks Outcast but I really want OEM gutted cats. I'm familiar with this type. Their cross section is round and concentric with the inlet/outlet pipes instead of oblong and offset like the original cats. My experience has been, when you put them on a 355, they either come very close or actually hit the rear motor mount central bolt unless they are field modified. They also don't have any adjustment at the muffler which leaves no room for alignment. The OEM cats have an adjustable flange that can be slid back and forth. This allows you to match the exhaust tip projection at the bumper.

    No problem dude, just throwing it out there. I have the actual cats (this type) on my car, and they are close but they do not hit. If they DO hit, that usually means you have a mis-alignment somewhere else in the system. I have Ferrari Challenge exhaust, and its position is dictated by the adjustment of the hangar. Fits perfectly.
