Question cobb stage 2 questions.

Hey all,
I just got my bonus check from work and want to put it towards my wrx. I just ordered an access port(for stg2 93 oct) and already have a Txs rfl muffler and Bosal downpipe. My question is would my money be better spent buying a catback(bosal) or Hotchkis sways(front and back). I understand they are completely different mods, but I need to know if I need the catback to see gains. Would the catback make a big difference in power I FEEL? If not, I was concidering the sways. Any suggestions? Thanks for your help.

P.S.
Is there a pipe TXS I can buy that will make my RFL muffer a full catback(mate from my stock 3rdcat to my axle back)?

I would go with the sway bro. When i got my catback (greddy evo) i did not notice much of a gain. Just noise. I am going to get some hotchkis sways also. I think that would more fun and a better overall up grade. You have to get new endlinks though and those are like 200 for a set of 4

I agree. The muffler is the major restriction in the catback.

Do I need the endlinks just to make the new sways fit, or do they help increase the handling? Also, I've never upgraded sways on any of my previous cars. What do they do. I know they will make my car feel more neutral through the corners, but what does that mean--will they eliminate the body roll? Thanks again, BK

Have you already replaced your up-pipe, if you're going to be running cobb stg 2, I know i'd think about it before you clog up your cat and have bits and pieces of it flying into your turbo.....

Has this actually happened to someone who is simply running a stage 2 setup?

i haven't heard of anyone that this has happened to but i am sure that it might happen. I would not worry about not having an up pipe installed for your cobb stage 2 as it is not required by cobb. The cat is fixed to the up pipe so well that it took me 6 hours to get the whole thing cleaned out. Mind you i was also using high powered drills and chizzles to do this.

I thought turbo back was required for stage 2?
On this page look at part number AE-WRX-0202-91
http://cobbtuning.com/wrx/accessecu.html (3rd row down).

Just want to be sure, because stage 2 was going to be the first thing I did after installing my turbo back.

For the best gains, you need a turboback. The only REQUIREMENT is a downpipe.

Thanks for the clarification. I'll be doing the turbo back first anyway, so no worries for me.

get the turbo back it yields a considerable gain and reduces spool, i'd go for an uppipe too just cuz no cats is great

plus if you already bought the accessport you can take full advantage of stage 2 with a catless setup

go for sways down the road

Hey,

Cobb states that you still are stage II even if YOU STILL HAVE the third stock cat. You only need to remove the second downpipe cat. You probably should remove or gut the stock uppipe cat for peace of mind.

I would leave the 3rd cat in place... its not like that extra little bit is goint to make much of a difference. If you were that into you would go with a bigger turbo....

I upgraded my 2004 with the Cusco 22mm sway bar and GT-Spec solid endlinks. The handling is MUCH improved. Stock setup has built-in understeer (front end plows through turns instead of gripping) and adding a larger rear sway bar and solid endlinks has made my car pretty much neutral (front and rear drift equally.) Oversteer would mean the rear end swings out around a corner before the front.

I still use the stock RE92s which are not very good in dry/wet but have been decent in the snow this year. I imagine better tires might improve the handling as much as the sway bar.

Is it recommended to replace both the front and the back sways, or just the rear? How much of an improvement are the endlinks good for--just the rear or both? Thanks much, BK

i have read that the endlinks don't make a huge diff. but they won't break like the stock ones might.

COOL! Thanks for everyone's input. I guess I'll be ordering some sways as soon as it warms up a bit. The catback and highflow cat will have to wait... for now. Thanks again, BK

depends how stiff your rear sway bar is? I have the perrin adjustable rear sway and I initially set it the middle setting which is equivalent to 24mm. I thought it was a bit too much oversteer and abrupt when it happened, I am now running the weakest settting == 22mm and it seems very balanced so far. So if you want to run stiffer rear, 24mm or greater then you might want to replace the front. Otherwise I think 22mm in the back is a good match for the stock front 20mm.

I have stock endlinks

You dont need to get front and rear sway bars. I got a rear sway bar, set it to 22m, i noticed a difference the first turn i made. It does not reduce body roll, it just makes the car turn-in so much crisper. A catback, you will notice some gains, but not that much power. I say save your money and dont buy a front swaybar, the point is to reduce understeer not encouarge it. Plus, the wrx has plenty of power as it is, add better handing and youll have lots more fun!

I say get a maddad 3rd cat eliminator to improve your exhaust flow for the cobb stage 2. Keep your midpipe. It is good for sound damping purposes.

i think stromung makes a 3rd cat eliminator and high flow cat/mid pipes. as for end links vs. sway bars, my impression is that whatever people change first is what they think made the most difference. i did rear links and sway bar with the whiteline heavy duty mounts and have been quite happy. for the money you'ld spend on a front bar you can change the alignment settings and tire pressures, will be pretty damn happy, and have money left over towards a short shiffter, morrettes, brake pads, yadda, yadda, yadda. just my long winded 2 cent which most likely belongs in the brakes and suspension section.
