The 300M Cat-back dual exhaust is supposed to fit the 2nd Gen Intrepid but I don't know first hand (I don't have it on mine yet). Do a search under the 2nd Gen forums for "Dual exhaust". You should get a few posts that might help. Of course by the end of the day you should have a few more replies with first hand knowledge.
"Kinda" Pricey?? ?? You better bend over and lube up cauz you're about to get fucked over on that one... I'm not doubting that it would sound nice, but holy shit, $1400???? If you're going to spend that much cash, why not go for a NOS kit or something else more than just an exhaust.
I'm pretty sure you could get a custom job done cheaper than that. To get it done like mine would only be about $225-$250... but hey, its your money - do what you want with it.
I also priced the Borla cat-back, found it for $754 + shipping. Summit I think, if not there then at Jeg's. The thing that killed it for me was the outrageous shipping to Guam. Dang!!! Oh, the part #14835F
