Borla Exhaust

Did GMC do any changes on the exhaust from 2003 to 2004 for the Envoy.?
Borla does not list any Part numbers for the 2004 Envoy.

If they didn't I would guess then I can use the 2002/3 Borla PN.

Hey just wondering if you put the borla kit on your truck and if it sounds good and did you notice any more power?

put the borla cat back system on my 03 envoy. noticed a big difference in power all the way through. also have an intake

also at idle can't really hear the exhaust but when you get on it it sounds like a V8. very happy with the system

Is the system much more louder at a highway speed and what about city driving if you are not coming on to it ?
I do like that the envoy's stock exhaust , sound's quiet but I do like preformance cat back system's but have not heard one on an Envoy.
