Hello,

I need a new cat and was wondering if a 2" would fit in the stock exhaust pipng of an 87 hf carbd. thanks a lot. i measured the pipe it seemed like it was ~1.5-1.75

Yes you could. You would have to use reducing fittings and weld them into place. But why not run 2" all the way?

You need to go an auto supply store and source out the reducing fittings yourself.

Why don't you head to a wrecker and take a cat off an later model SIR or GSR - heck a GS would even do.
