Slp 4th gen headers?
I've done a little searching and found that only 4th gen shorties will work on a third generation. Couldn't find anything on mid lengths, more specifically these Slps? Has anyone used these on s third gen before? Thanks in advance

Assume they won't. Just get a 3rd gen header and forget the 4th gen stuff. Its not worth the hassle.

They may get close but with the differences in suspensions/firewall and a few other things I'd bet they'll hit someplace. The Y pipe is def different.

I already own the headers. I was just curious is all. I guess I'll have to test fit them one day. Laying my Slp third gen headers on these they're pretty close in collector location which is why I asked.
