I have a WRX on a 04 plate which is completely standard.

I am after replacing the back box and centre section, not sure about downpipe, probably leave it for the moment, especially considering waranty.

Questions are, What make, and where to have it fitted? Recommendations please. I live in Kent. It seems H&S are recommended on here.

I am basically after more power and can tolerate moderate extra noise.

After fitting, do I have to do anything else? Sensor frig etc?


Thanks in advance

Pick up a Prodrive back box & Prodrive decatted small length centre section off ebay for about £250.
Warranty friendly and the centre section won't need any sensor fix.
Leave the longer part of the centr section as std.
D/pipe swaps are unlikely to be warranty friendly, but you could always try a prodrive sports cat for approx £200-£250 s/hand, again off Ebay.

Don't expect too much in terms of power gains from a centre section and backbox per se; the main improvement will be in noise. H&S's Afterburner vortex system is highly regarded in terms of noise and power. Do make sure that your dealer is ok with the changes or you may void your warranty- most wil be ok with the back box and centre section, but no more.

Thanks for the info..

Anyone recomend someone localish to me to buy from / fit? Many years ago I used to go to Scoobysport in Essex but there must be more local.

I'd consider going to a local meet and listening to some other exhausts. I've just bought a scoobysport back box and love it, better than the big 4 1/2 inch jap spec I had on when I bought the car which was lovely on country lanes but torture on long motorway.

Also just bought a Prodrive Hi-flow Cat downpipe and will be fitting with a decat up-pipe (already have decat centre) soon. So I'll let you know what improvement I get. Prodrive Cat Downpipe should stay warranty friendy ??

Hi Again

Just bringing this up again

I have gone into it a bit and still not totally sure what system to get. All manufactures say there system is the best, Power Engineering T75, Blitz,HKS, H&S, magnex, scorpion. There are just too many.

Seems I am going to go for H&S backbox and centre, hopefully this weekend. Right decision?
Money isnt the main factor but moderate noise and more power is - even if it is only going to be a fe extra bhp.

Another question for me to debate....should I get a performace air filter?

You won't be disappointed with the H&S. I've got the jap style back box. Great sound and not too obtrusive in the car.
