1. You don't have to replace the gear to add a posi. Athough I would recomend a change to at least a 3:73. I have had good luck with my Auburn posi. I know a lot of people would agree me. I also know one N20 junkie that doesn't like them <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> hint N20er hint <img border="0" title="" alt="[Razz]" src="gr_tounge.gif" /> I had my 3:73, Auburn posi, carrier and labor done at MTI for about 1 grand.

2. Unless you buy a premade cat back you should be able to get into a true dual ,X pipe, 2 mufflers and labor for less than $400. Aftermarket bolt up systems will cost anywhere from $250 to $750.

 

what kind of muffler would you guys suggest?

 

you cant really just suggest a muffler. everybody likes different things, some people like quiet and some people like to be able to wake up our friends in europe <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> its all a matter of taste...

what are you looking for?

 

I would recommend the Eaton locker. It is not clunky and strong. The factory locker sucks. That is probably why the one was on e-bay. It doesn't engage both wheels very quick and the locking portion kicks out above 20 mph, per GM. Since I drive on an ocassional ice patch I can verify that it will spin one wheel above 20. I have 4.10's and it is not too low of a gear.

 

The factory locker is or at least was made by Eaton.

Heehee, I used the new graemlin.

 

spintech makes a catback that is true dual with an x-pipe in it for $399 both tips exist the passanger sie before the wheel

as far as mufflers, i'm mostly looking for best performance but i wouldn't mind waking up the neighbors either.
