Had the 03WRX a year now and fancy beefing up the sound without aggravating the neighbours, ruining refinement or looking like a tw*t.
I don't want to invalidate the warranty so would a Prodrive back box fit the bill, do you think?
Thanks.

 

I have fitted a MilTek back box only recently, the sound is much improved without pi55ing off the neighbours, got better breating for the engine and checked with the warranty company and they approved it

Was only about £170.00 - bargin

Looks good with 5" single pipe and resonator inside so that it doesnt look like a drain pipe!!!

 

Sounds good.

When you say warranty company do you mean Subaru?
Where do you get 'em?

 

Yes! or the WR Sport one that I have, same box but with an oval exit. Both of them are made by Subaru so shouldnt harm you warrenty as long as they are fitted by a dealer.

 

I thought i saw a wr sport in the for sale section the other day, and i'm sure you could fit it yourself and still keep the warranty.
