Exhaust Size

[HTRK-1]

Hi guys, Does anyone know what my stock exhaust size is going into the mufflers. My car is a '93. I need to know what size clamp to buy. I'm installing a set of Magnaflow 15623's. Thanks in advance. They should be here this week. Also is my stock exhaust stainless steal?

The 15623 comes with the mufflers clamps and hangers. Once you cut your factory pipes and drop the original mufflers. You can slide the Magnaalfows over and slip the welded on lip into the hanger. Then use the supplied stainless steel clamps to lock them down. Or just get them welded on. They fit nicely.
I just hope yours don't resonate like mine did...
