Sweet.
Alright I measured the Resonator + Cat, the total length is about 40 inches.
So I can either find a 40 In long Resonator (which seems hard to do)
Or leave my current gutted cat, or try to find a 97 CAT.
Thank you Swiss for this information, it can be found
here
If I leave my current one, it is approx 13 3/4" long, requiring me about 27"-28" Resonator
If I get a 97 CAT, is is approx 12 5/16" long, Requiring me a 28"-29" long resonator
So basically the Resonator that classicaddict posted
Or
this one just shortened:
