What Exhaust Setup?
I'd also recommend that you do Poly tranny AND motor mounts while you have the exhaust off. And it may be worth getting the Mufflex Y pipe hanger, all of these are available from Thunder Racing.
As for catback, well there's lots out there. www.ls1sounds.com has some good clips.
You need to decide what sort of tone and volume you would like.
Personally I think the LM is an excellent chioce of catback, stainlees steel and well made, but be warned it is LOUD. Well after all it is called a Loudmouth.
For preference it will sound better with CATS. If you go ORY you will probably want to swap the LM resonator ot to a Borla XR-1 or Maganflow bullet muffler. This will control the sound better and offer better tone, but it will still be loud.
If you think you will like the sound of the LM you will probably hate the Hooker catback. And vice versa.
GMMG, Stainless Works chambered and Powerpack catbacks all sound great but are pricey.
Mganaflow, Corsa and Borla are all popular but not my sort of thing. But there are many more.
Only one to aviod is the Flowmaster American Thunder, it sounds good but it isn't so good from a performance standpoint and is quite restrictive on a modyfied LS1.
