Hey Mondie, I have the '07 built MY08 GT-B (Wagon) Non Sti.
I recently fitted a custom made 3" Stainless exhaust (Buttler Built Products) Norm Buttler hand makes all his own mufflers and the work is superb. I had the ECU-Tec Tune at Maximum Motorsport here in Perth. It now has more than adequate performance and a really nice, unique note. 2.5 GT's have a traditional single scroll turbo, unlike your previous 2.0 twin scroll that would have sounded like a Fiat with a hole in the muffler. Mine sounds like a WRX at low R/min and cruise speed but in S# mode at full throttle it sounds European, like a 6 cylinder Beemer. It must be the twin mufflers I suspect. It's gone from 142 KW to 159 KW at the wheels. And from 282 NM to 349NM. It also livened up the dead E-Throttle. I thoroughly recomend it. S&J in Adelaide do it too. It won't alter tune/economy in I mode either.
The 6 speed is the way all turbo Subaru should be made in the first place, 5 speeds suck. The Auto sucks too in my opinion.
I have Brembo's and rims to go on shortly so I'll end up close to STi spec eventually.
The 6 speed fitted to the MY07+ GT, GT spec B and the "Tuned By" are all the same as each other, as strong as a WRX STi box but have slightly longer ratios. Mine has a lanky shifter, I suspect the Tuned model has a shorter throw.

The car l will be looking at probably tomorrow has already been fitted with a full 3" system and Ecutek4 tune so it should sound the part and go pretty well too. Will report back after l have boought it,

come on Mondie, go with the Liberty TB STI. I got 154 kw and 355 Nm on just the flash tune alone and sounds great now. New dump and larger i/c will net even more improvement on dyno numbers as well. Evo interior is poverty spec imo but it all depends on how much time you expect to spend at the track vs daily driving I guess.

Very true, the Evo interior is the only thing l am still undecided on. The STi Lin l drove this morning was great 190awkw and nice handling too. They have made a lot of worthwhile improvements since the MY06 model.
l live in the Adelaide Hills so its perfect driving country, that's why the Evo is so damn tempting. l will be taking the Evo for a run this afternoon, having never driven one l will ultimately let the driving experience decide which to go for
Cheers,

Hi mate,
Whats involved in these mods, it already has a front & rear sway bars factory l think ? Plus factory strut brace. Keen to know what can be done with next to no mods (and cost )
Cheers,
Mondie
