Which Exhaust? HKS, Greddy, Veilside, Blitz, SP Engineering reviews on exhausts Options

[west_minist]

This may not interest everyone, but for those of you looking for middle to top end performance and beyond, this thread is for you.

I just want to warn you that these exhaust are not cheap. But HP is not cheap at all to.

I found this review very interesting in how exhausts can actual change your dyno graphs.

Either way, check out that famous Supra Website T04R.

I would recommend a serious normal mods (High Flow intake, Racing plugs, Adjustable Fuel regulator, Apexi SAFC, Ignition Controller + Nology M80 Coil, Plug wires, Ground wires and very very very Good Tuning) to take full advantage of these exhaust.

Since these are turbo muffler, there have more flow characteristic than a street one. So if you want to upgrade you piping, (I do not know, but a gut feeling) use up to 2.25" for ST and up to 2.5" for GT. There is a high possibility that you will lose low end everything. But this can be combat by more fuel and tuning, sine you now have less back pressure that had stopped you in the first place

At this point, I would welcome ST & GT owns to contribute here, if there have such custom piping and have also done dyno testing for verying pipe sizing.
