I am looking for a set of weld in SFC's that will work with the dual cat y pipe. The cats are gone and bypassed......

I need something that will work with both the dual cat and single cat y pipe because i'm switching when i put my headers in.

Thanks in advance :hail:

 

South Side Machine's don't fit w/ a dual cat. With some minor modification (a fabricated bracket) I was able to silence the rattling, though. It was the AIR tube rattling between the pipe and SFC.

 

I had the ones from Spohn welded in and they were great.

 

i got a set of macs, they work wiyh dual cats and are awesome
