Tim, one of the founders/owners of PDX, tuned our car. It's making some pretty good numbers. Now we need to get the suspension stuff all sorted out.

So on the STi, 27mm bar out front and the stock rear bar in back is not too much of a difference in strenght for the car? I was worried about that and was only planing to run a 24mm in front. However this is what the rest of my parts are looking like. Haven't run the car like this but here are the parts.

Cobb SF intake (installed)
Maddad V2 downpipe, ApexI WS Noir Catback (installed)
Zeal V6 Coilovers with 12k10k or 8k option, front and rear camber plates (not installed)
FSB? rear stock
Stock gold bbs wrapped in Azenis ST-615 245/45/r17 (not installed)
Kartboy or Whiteline endlinks? (still undecided)
Don't know the align specs yet
I have a Cobb AP but unless I find some one that has s map or makes a STU map for me, I have to run the stock map.

Just an FYI for ya. If you dont find any good tuners in your area that you trust to get you a ST* legal tune. You can get a mail ordered one from pdx. Check out their wedsite http://www.pdxtuning.com/. They cost about $175 and that will include a stage 2 map and a few others.

So I've got an appointment for a tune on April 6th and I'm trying to settle on the TBE.

#1 priority is power. PDX indicated they've had good luck with the TXS TBE exhausts getting good power for a catted system. I also *prefer* the stock-ish look of a straight-back exit and want a mid-level in terms of noise, which is why they're suggesting the TXS.

What do y'all think?

I think you have your priorities backwards and that your #1 priority should be grip as that makes the most time. That being said, I think their depiction of the TurboXS turboback system is right on the money as I used to have one.

edit: Wait a minute, aren't you a national champion? If that's the case, then did you mean '#1 priority regarding the exhaust choices' ?

Yup, I've got the suspension on order and already have the wheels/tires, which should be what I need in the "grip" category!

The # 1 priority I was mentioning was JUST for the exhaust system in terms of getting the custom tune... I'd give up my looks/sound preferences for better power, but all else being equal, I'd love to have the best of all worlds - highest power, good stock-ish looks and not-too-obnoxious sound!

The TXS turboback isn't loud at all; I used to run one on my previous STX WRX. That first post was a knee-jerk as usually it's a bunch of n00bs who think that power is going to make them faster.

Bucshur Racing has a new "quiet" exhaust that only gives up around 5hp from a straight through in stg 2 set up. Might be less on a STU tune due to lower boost levels? I have never heard it myself that why I put "quiet" in parenthesis. I've had a Borla Hush which really isn't very hush .

What about weight? Are there exhaust systems that provide all the power and fit but weigh less than any other?

But Buschur chose to put the cat near the turbo. His design and parts sourced meant that either a cat or a flex joint was to be welded into the same spot, depending on the customer's needs. From everything I've read for STX/STU, you want the cat to be as far back from the turbo as allowed if you want power.

His CB can be used with any DP that works with stock exhaust.

Give Dale at Boxer4Racing.com a call. I just got my TBE from him. I went with a BPM, with a sererated wastegate downpipe. This is the first TBE from BPM on an 06+ Subaru STi. its a full 3" exhaust, TIG welds, a true metal substrate cat, and the quality is absolutely beautiful! And the sound, the sound is awesome! We are trying to get the car on the dyno to get some numbers and see how it compares to the COBB and Stromung. It sounds much better than those! It is light weight too. Be sure to tell him Crash sent you.

Thanks guys for all the input! I've been working with Patrick at Boxer4racing to get my swaybars, I'll shoot him a note on the exhaust. PDX was pretty confident they could eek out great power with the TXS, so it'll be interesting to see what other options are out there.

Oh, I noticed a lot of the lightweight exhausts are the noisier ones... does anyone make a lightweight (i.e. Ti) exhaust that isn't stupid loud? I really don't mind some noise, I just don't want my neighbors throwing things on my car when I leave at 6:30am to go to work!

Try checking out the new Greddy Ti exhaust. It just came out so I dont think anyone has one yet but the db levels look pretty good with the resonator installed. Im not sure if its a full Ti or how much it weighs but the price is pretty resonable for a Ti catback.

Annie, I'm running a Cobb DP and Greddy Evo2 cat back. I chose the Evo2 because it does have a moderate growl to it at WOT but doesn't drone at freeway speeds like some others. It also tucks nice and close to the bumper for an almost stock appearance. Personally, I'd make my choice based on volume and looks. I would consider a Ti system now though.

Thanks James!

So PDX is suggesting the TXS (or a Greddy CB with a different DP)
Boxer4Racing suggested the Cobb or Stromung
Others have suggested, well, others...

It's so hard to decide!

I dont really care about my DP choice, I will probably end up with a helix catted DP.

As for catbacks, I really like my Borla XR-1 catback, it looks VERY stock and isnt too loud IMO.... its widely accepted as one of the mid way exhausts as far as sound goes.

Those of you with 93 Octane ST* tunes. Do you use them on the street? Basically is that the only map you use with the car or do you reflash to another map (say stage 2) when you drive to and from events?

We reflash....realtime for local stuff and ST as a base map for Nationals & stuff

The STU tune is pretty agressive and TopSpeed told us not to run the car hard in 4th, 5th, and 6th with the STU map loaded.

Cruising is no problem with the 93 map, but it does suck some gas

You might check out the ZeroSports exhaust. It's really quiet, and supposedly made out of thin-wall stainless steel so that its weight is competetive with Titanium.

Yea ive heard of people saying that you should be easy on the car if you get above 3rd gear but wasnt sure if it was true. But its easy enough to switch realtime maps.

Thanks.

Default wheel width

A noob question - based on the posts it looks like ~1/2 the group is running 245s on 8" rims and the rest are running 245s on either 8 1/2" or 9" rims. Is there any strong argument one way or another? It seems like a trade-off between extra rim weight and better sidewall support, but I'm not sure.
