....fix that exhaust, replace the mid-pipe with an x or h... personally i would do shorty smog headers w/hiflow cats, and then you are ready for a nice NA cam. maybe add a rear sway bar if you don't already have one, then get a nice tune.... there is also other ways to stiffen up that vert like sub-frame connectors. do you have a t5 or 4r70w?

i already have subframes, but no rear sway.
you think its worth upgrading stock to new shorties? i thought i heard the stockers were pretty good.
and right now there are 4 cats in the car if im not mistaken. replace all of them youre saying? or just the 2.

also, what do you mean by 'smog headers' i thought shorty headers were all basically the same (as far as emmisions goes) . i could be wrong though..

you think i can get a good cam without changing the heads? how much you think i can get of the stock motor with a new cam?



oh, and i have an Auto

heres what i did if you want to know: i left the stock headers and first 2 small cats and then ran stainless 2.5" mandrel bent tubes to an H pipe to my mufflers in the magnaflow catback. it sound like flowmasters but louder and deeper now. so it is much more agressive without the 2 cats, and ill still be 49state legal

i see, so in short youre saying, caut after the first two cats and throw an h pipe in there. ill find out if the guy i know i will do that stuff for me. did you do actually feel any difference in low and after doing that or just the sound.

[AtlanticBlue99]

low end power seems lacking a little, but it may be my bigger wheels/tires out back. i did both in one day. it may just feel lack because it picks up more above 3500 rpms and pulls hard. you know, i cant really feel a difference to tell the truth, it just sounds mean down low and insane up high, at first i was annoyed with the sound, but after hearing a local cobra with o/r midpipe and LM1s, i am happy with my sound lol.

the stock headers are ok and flow decent, but if your trying to go NA then basically you need to squeeze a little power from everywhere, that will add up to the big picture. I would take all 4 cats and trash them for two hiflows or just get a catted h or x pipe, but obviously this all depends on your budget. Yeh the shorty's have smog bungs on them, but I was just trying to add that so you knew why I wasn't sugguesting long tubes.

hey 1clean6 did you ever dyno your's? if im not mistaken his sixer is cammed with exhaust/intake work and gears...

without a 8.8 rear and slicks i would say that a NA sixer would be still in the 14's, but if you did head work it could be a 13 second NA car even with radials. Without head work I just don't see you putting down much over 210hp to the rear wheels.

the rear sway bar does make a differance on corners, even on an already lowered car with stock control arms, and is a true bolt on. to save some money just get a take off from a GT.

here is some more info you can read up on:

2 high flow cats is enough for emmisions i assume? in that case i should go look for 2 of those and have them make me an H pipe, or look for a catted H. ill get on that soon i guess, any advice as far as brands and stuff with that stuff?

and as far as cam/heads - does it make sense to get a cam and get heads later on, or to get them both at the same time..

Hasnt been dyno'd yet, but Im hoping for ~270rwhp.

Headers are a waste unless your ported/cammed, youre more than likely going to lose power than gain it.

[99mustang232]

your only gonna find re-worked OEM heads, to my knowlege there aren't any aftermarket heads avail. You can do them seperate but if you plan on working the heads do the heads and cam together, because your cam affects how your heads are configured. you could probably get a h/c package from Mikael at rpm-mustangs.com As long as you have the cats and smog pump still hooked up you should be fine on testing, where do you live? MAC makes a v6 hiflow catted H-pipe... to get feedback on some of the parts you might want to search over on v6power.net or 3.8mustang.com

i was originally going to get a head/cam package from super6ms, but now it sounds like i should just look for a good NA cam and go from there.

what else did you do to get to 270rwhp?
