Recently had the
MRT Dump pipe & centre section (kept stock STi mufflers),
Hyperflow TMIC
CAI (pod & adaptor)
& EcuTeK retune and hit around 178kW at the wheels.. There are a few other cars on here with similar mods & power out puts.. The change is incredible..
The pod it quite noisy.. I don’t mind it at the moment because it’s a bit of a novelty, I will eventually get a cover for it and this is meant to reduce the suction noise quite a bit..
I don’t really think there is much difference between the AVO / Hyperflow gear.. Its just depends on who you prefer to deal with..
With regards to the different exhausts, most of the change in note (increase in noise) comes from changing the mufflers, but if you’re keeping the STi mufflers the you will gat a bit more rumble but definitely no drone what so ever….. I pretty much can’t hear my exhaust over the suction noise of the pod (the pod is quite loud).. I can hear a few pops from the exhaust when I down change through the gears thou.. Next time I am back (three weeks) I want to fabricate a noise dampening cover for the pod (maybe fill my engine bay with egg cartons… jks..), so I can get a better idea of how the exhaust sounds… or get someone else to do a drive by in my car.. I also cant see there being too much difference in the performance of the dump pipes.. Just don’t go with the super cheapo’s, you get what you pay for, but most of the better dump pipes are probably all pretty similar..
You will definitely notice a massive improvement in performance with these mods.. Esp Dump Pipe..
