Hi I'll soon be getting a forester sti and am looking at exhaust options I'm only looking for more sound rather than chasing bhp (for the moment lol) so a cat back will do, now by what I can tell is the centre pipe has a cat fitted, i was looking to get a centre section and a back box will getting rid of the cat fail mot's as it still had the other cat in place, also will it throw up a cel light and will it need remapping with just the one cat gone, it will be getting mapped at some point anyway any help on any more mods worth doing and info about exhausts would be great thanks

 

Nope, the downpipe has the cat in on the 2004 FSTI. The centre pipe is just another resonated pipe. Just changing the centre pipe and rear box won't throw a cel up and won't need a remap. Changing the cat in the downpipe would though.


Go on ukforester.com and subaruforester.org lots of us with FSTI's are already on there.


Welcome to the club. You won't regret it. These are fantastic cars.

 

Great stuff thanks mate so the 2 parts on the centre pipe are just resonators, any suggestions for exhaust, quite like the look of the vortex afterburner or raptor, can the angled box be fitted or does it have to be the straight one, I'll have a look at the other sites, can't wait to get it arrives in May ready for June It's feeling like a long wait lol

 

Both good exhausts. have a look on those 2 sites as there may be Forester STI specific exhausts come up from time to time, also on the Facebook groups. Someone was selling a genuine STI genome rear box and centre pipe recently for a FSTI. I have that on mine and it's just perfect!

Also be aware that the Forester has a slightly different exhaust system to the impreza, so impreza exhausts won't fit without modification. An Impreza classic rear box will fit, but the hangers will need moving/re-welding. The FSTi centre pipe is longer than the impreza centre pipe.

You're best off looking for the forester specific bits.

 

That was me selling the exhaust.it lives in holland now..

 

Thought it was Ryan.

 

Have you seen the forged 04 fsti on gumtree??oh my days!!! Just needs some styling and it would be great.

 

Funnily enough I was looking at that last night. Would be interested to see how much it goes for as it's a 140k mile car as it's advertised for £15.5k. EEK.


For that money I'd rather get mine forged. Paul Finch could forge mine for £3.5k and then I'll probably still spend another £5k on parts to make better power.

 

Didnt see the mileage.thats quite high.i think you should forge yours.was just looking to see if there any forged engines for sale/part ex/swap in the classifieds etc.have you seen project naughty??

 

Yeh that's Duncans car isn't it? I do like the colour and Paul built his 2.35 engine too. Paul builds all Duncans time attack engines, has done for years. Nice FSTI that. Looks like fun!
