It is after the cat. It helps a bit if you are looking for a 3.4 but not much. beleive it or not the stock cat and mufflers are quite free flowing, some say moreso then aftermarket so in essence all you are really doing is deleting the ubend and res [performance speaking].

Cheepest way to run a 3.4 safely
1) Cai = Less then $60 if you make it yourself
2) PCM = $100
3) Plog = $120
4) Colder Plugs [104's] =$10
5) 180* T-stat = $10
6)3" DP = $140 bolt in offroad [no cat]. Get a used one MUCH cheaper, with cat for emissions.

Total = $380 is a cheep price to pay for a 3.4.

It can be done with less but this is a good estimate. Access to a scanner is a good thing to have also to see you Kr. Also if you plan on modding further get headers instead of the DP and plog. And a tuner instead of the PCM.
