BULLDOG

I will check when I get home . the wheels are stamped speedline and prodrive

HI, Can anyone give any advise on an induction kit for a 2.5 Sti. Are they any good? What is the best one? Do they increase performance? Where do I find one?

Hi Again I need help. I have a 2006 sti PPP and my Prodrive wheel centres are in bad shape. can anyone advise me where I can locate a full set of these to fit Speedline 18inch wheels?

it sounds to me like a wheel bearing. it can be very difficult to determine which one it is when driving as the sound can deceive you. I would also check the gear box oil level to be sure . there should be a dipstick around the bulk head to check this.

Thanks mate. I will have to start investigating my car now. It has a burble but not what I am used to with the 2litre engine. Like I had a 2 litre beside my car the other day with same prodrive system as mine and mine just did not have the same note. I put it down to the 2.5 being quieter

Hi, This is my first post here and need a bit of advice. I have always had 2.0L Impreza's over the years but recently purchased a 2.5L PPP one and have noticed how much quieter it is. It has the usual Prodrive back box I have had on my previous cars and I took out all the cats and silencer boxes and replaced them with straight through system but it has not gave me the same engine burble I had from my previous 2.0L PPP. As of yet I have not replaced the manifold as I am not sure what is the correct type to go for and if it would even make a difference. Can anyone advise me on how to increase the burble noise from the 2.5 or what should I try next. And even dose anyone know why the 2.5 is quieter? Your help would be appreciated.
