Hi, am after a backbox for my subaru impreza sport non-turbo...does any one know where i can get 1 from not too dear like on ebay asking for £150, just want a nice descent back box urgently thanks adam

 

Would a turbo back box fit a sport? can anyone answer please?

 

I would like a backbox that has that scooby power noise like a burble sort of noise, does any one know if a turbo back box will fir a non turbo sport? its a 1999 model thanks adam

 

I have looked on scoobyworld and the turbo backbox and sport backbox look the same on the pics and are priced the same, as for the noise I think that it is because of the boxer engine and a turbo backbox should make it a bit louder than your standard one.

 

I had a Magnex 6x4 back box on my Sport, it was originally on a Turbo so Turbo back box fitted hangers ok, it was the mating flanges that were different.

I couldn't put it straight on. I had to buy a centre section from Jap Innovations (This company gone now, but you may be able to get a 2nd hand one)
This had a (-*can't remember name*-mind gone blank!) in it to keep the back pressure up as car is normally aspirated not Turbo. You can't just put a Turbo centre section on! I know I tried! You would also lose low down power if you put a straight thru one on
I had to fudge the holes to get these to match up as mating flanges were slightly out to each other.

This made a big difference to the burble noise, but if you really want to release the flat four burble you need to be looking at a Borla manifold

If you get no joy on here, try imprezasport.net

Good luck pal - Darren
