Looking at getting FLP headers with cats and y-pipe.
Anyone knows if there are any clearance issues with SLP subframe connectors?

You list an LT1 and an LS1 in your profile..... which car are you asking about? May affect the answer????

Good point. It is for my LT1 ride.
To be specific, I have big heavy boxed 3-point SLP sub frame connectors.
I did some in-depth research, some guys reported front cross braces interference with FLP y-pipe. Dunno if this applies to LS1 style headers only.

I'm going to add the LT1 info to the topic.

Any long tube headers and y-pipe will fit with the SLP 3 point subframe connectors as I have both in my 94 Z28.

I would agree, the SLP SFCs meet at the tunnel brace, and should not impact your exhaust.
