On my Impreza STI (05) non PPP, just had fitted a H&S Centre section and backbox, now will I have increased the BHP atall?.

Thanks
Darren.

 

10bhp at the most without a remap

 

Erm,no.

I wouldn't have thought so for a minute.

 

Where from and how much?............

 

Negligable amount.

Change the cat pipe (£100), downpipe (£200) & remap (£650) & filter (£40) though and you'll have some big gains. (330/330 is within reach).

 

As far as your insurance premium is concerned, YES

 

For 10BHP gain...you have voided your warranty....

 

Yes but don't go racing those ferrari's at the moment.

 

DCI:- Exhaust ordered and fitted from Special Scoobies (Colchester), theres some pics in the Gallery.

Insurance has been notified thanks, and any warranty queries are sorted by putting the old exhaust back on.

 

Unfortunately if the worst came to the worst, you won't be able to swap the exhaust back to standard.

If you had a failure, then Subaru Assist will take it to the nearest dealer who examines the car - bearing in mind this may not be your original "Mod Friendly" dealer.

Subaru do inspect all engine failures now, whereas before they would have accepted the dealers word.

Tread carefully I'd say.

Errrr, don't call Subaru assist then!

 

Good job I'm with the AA then.

 

I would say you may have increased the power by all of 2 or 3brake at the most

 

Thats all I would have thought 2-5bhp. So its removing the cats that give off most the power?.
Not that I was after more power, just wanted a proper Scoobie sound track, which I have now!.
