i think im going to go with these mac ones from stang mods because my logic is that a mac hpipe and mac headers should match eachother.

http://www.stangmods.com/MAC-Headers-p/00178.htm
i like the lil part in the description that says bolts up to your mac h pipe

* i wish money was free or some dude just came up to me in the streets like hey dude ur exhaust is leaking here's 300 bucks to fix it* haha

i didnt know mac made O/R h pipes for shorties

well you said you are getting more cash now, i would just save up and get LTs, a mac h pipe to fit that and some high flows. thats the only way your going to get a better sound out of the v6. and if you want it to be really deep sounding and just plain retarded loud dump the exhaust before the axles

i met a guy at a car show last weekend with the sickest exhaust.
Nothing too special just a s197 GT with some flowmasters and an o/r x pipe
also had a whipple and 150 shot and a **** ton more

But he had a switch so he could run open headers and then he could switch it back to run normal.
It would like block the pipes and re route the exhaust right after the headers to just go out... needless to say it was loud

also if i hook up the o2 sensors with out cats will they throw a code


do you think i could sell my stuff on there
-stock manifold and
- mac o/r h-pipe with cats custom welded in
how much would they be worth???

i think your better off keeping the cats. i heard taking them off loses you some low end torque. if i had the money i wuld prolly buy them i want to put some hi flows on mine.

If you do lose low end torque from not having cats, dont you gain it back from having LT's?

No way you would pass emissions unless you put some cats in there.
The rear O2's will throw a code but it's just because the cats arn't there.
stock manifolds - $50 for the set.
Mac H pipe with cats - $150-200 maybe?

No, you do not lose torque, you effectively move the power band higher up in the RPM;s. I have a dyno graph to prove it if you want to see it.
