I bigger diameter uppipe might hurt spool just a little bit, but it does make MORE POWER than smaller diameter ones. This has been tested many times (gruppe-s bieng one of them), and they recommend larger diameter uppipes. All4bspinnin is correct. By the looks of it, this is a GREAT kit for the money and it WILL perform very well on a ported turbo mid-size turbo (tdo5-06).

This bieng on an STi block, of course. 2.5 liter engines have higher manifold backpressures, so for 2.0 you might want a smaller uppipe.

There is about a 100% chance you will have fitment issues.

1.) that downpipe doensn't curve horizontally like it should. The subie exhaust starts on the right side of the car and moves left. This dp won't fit in into the groves under you car that are designed for the dp

2.) the header will probably hit your oil filter and the flanges won't lign up. I was going to get this until I read about the tons of fitment issues. + the welds have been known to crack

3.) That catback section definatly doesn't look like it'll fit.

But for $400, it's worth a shot.

Almost none of the ebay items fit correctly, it's just a matter for finding a cost effective solution to making them fit.

There's entire threads dedicated to this issue, but the general consensus by tuners was that you lose spool and power with a bigger uppipe until you get into the big daddy of turbos like a gt35r.

The original poster has a stock turbo.

Most companies make uppipes that posess i.d.'s of 2inches for less for a reason, there's also a reason why the stock uppipe is the diameter that it is - and its not for emission reasons.

Headers like the gruppe s, you may gain some peak power but at the expensive of the entire midrange power band being effected negatively. To me, thats not really gains.

Maddad just came out with a V2 header for this very reason. They developed a smaller uppipe to see better gains.

why oh why put crappy parts on a NEW car.

just buy genuine stuff thats been proven. no matter what people say 99% of the time, you get what you pay for.

and why get the header anyways?

if you want cheap, get an spt catback or a quality used exhaust in the classifides.

I have the TBE from off ebay and let me tell you I couldnt be happier. I know its cheap but hey I would have to pay 1200 bucks for the exhaust that I got off ebay for 299.00 bucks. Name brand stuff like exhaust parts are way over priced. Its just a bunch of metal pipe for Christ sakes. Yeah it maybe wont last as long as the expensive stuff but I could buy four sets of exhaust before I even get close to one set of expensive exhaust. I will state I have seen problems with the headers cracking.

There is nothing wrong with trying to go fast for cheap.
Name Brand Stage Two
TBE $800.00-$1100.00
Uppipe $150.00-$250.00
Cobb Access Port $500.00
So its between $1450.00-1850.00 for a stage two.

My Stage Two
Ebay TBE with uppipe. $300.00
Cobb stage two tune from local guy $50.00
Total $350.00

Wow you can spend more money and have the same power that I paid 350 bucks for. I think I will be cheap where I can be.

for 399 plus a little bit you can get yourself a really decent used detup. hell, theres a guy in texas selling a carbon Ti muffler for 250, and it looks good from the pics he sent me. and a quality mid pipe plus down should not be more than 400. check out the vendors on this site, they have some really good deals, and most of them are pretty honest.

650 isnt bad for a full tbe, but for a little more, you can get a brand new tbe around 8-900.

Vary true. I would have to say our vendors on this board a top notch. I have bugged them with questions on products and prices and they go all out to get you the best price they can. I am planning on getting a new turbo from one of the vendors on this site.

I don't know if you guys realize this, but he got a header/uppipe AND turboback for $450 shipped. You can't match that, even used.

Hell, it's worth it just for the steel almost. Get it, put it on, re-weld and problem areas, coat it, and you've got a perfectly good exhaust for half the cost of a regular setup.

this exhaust can not be beat for the money.

as you are installing, i would pay careful attention to header flange tolerances and the possibility of cracking in the future due to greater heat rejection from the engine.

heat wrap the headers and you should be good to go.

I put this same system on my friends wrx and I had one little issue and that was that the hangers on the muffler weren't quite right and really stretched out the rubber exhaust hangers, so he just got some of those super stiff ones, I don't remember from where. I have an ebay downpipe that has held up really well.

Wouldn't heat wrapping them cause them to crack much sooner due to heat fatigue?

Kinda looks like a rip off of a Invidia N1. I wouldn't buy a eBay piece but thats just me. I believe in you get what you pay for. Id rather buy a used high quality piece like Invidia or something. Anyway that one looks decent, good luck with it.

For a while I was running that turboback that the OP posted. Absolutely no fittment issues, infact it fit better than my Helix setup. The lump in the downpipe isn't a cat, its a resonator. The pieces are non-standard length, so no mix and matching catbacks and downpipes here.

The welds on the catback and downpipe are excellent and look robotically welded.

The downpipe is made from a few separate pieces welded together. The area where the bellmouth is welded to the tubing is a little rough, they didn't bother to weld or smooth the inside of the pipe so you may get this very sharp transition on the inside of the bellmouth. I ran it for a month on Cobb stage 2 without problems.

The headers and uppipe need more refinement. The headers, while they work, will eventually crack. The uppipe has some fittment issues and really isn't useful unless you had a catted uppipe like the WRX's.

Overall its a good setup for the money. However, i'd spend the money on a slightly higher version of the eBay catback exhaust and get a better name brand downpipe like TiTek\Helix\Invidia\Maddad. I am currently running the SR*S catback and it fits like a dream and looks great if you are into the N1 canister look and it sounds deep and mellow (but loud). That setup is standard length and will bolt up to any downpipe and costs around $200 shipped.
