i know this might be a retarded question...but if you already have a precat'ed downpipe, can you just put on a fed spec downpipe to replace it? im assuming the headers are the same but im just making sure
Not sure exactly. All I know is that I've asked the same question and people told me they weren't interchangeable without modification. Hopefully someone will post here with answers
Nope they are completely different. The lengths are different and the manis are different. As well as Cali-spec has 4 02's and Fed Spec has 1. I am changing manifolds and having a custom downpipe made. If you bought a fed spec dp you need to return it to get a Cali unless you want to chop the fed spec and make it fit. Good luck.
yeah i emailed 3sx and im going to ship back the fed spec in trade for a cali spec. just gotta pay the cost of shipping
