I have some plans for this winter. I want to do Pace setter headers on my 3.1 V6 and I hear You have to finagle with the smog pump. Is there a bypass pully for sale out there that I have not found or can I re route the belt somehow (I do not have A/C)

Also I no longer need to take emmisions. I want to cut off my Cat and put a straight pipe in its place. I have a nice Dynomax cat back system, will I get a ***** poping noise with no cat or should I just do a high output cat. Thinking of trying the straight pipe first and if I dont like it cut it off and put a nice cat in.
