Hey folks, Just got a 56 plate WRX and wanted some opinions on what back box to get, its still standard and well obvious reasons want something that does not hide the noise.

I understand the 2006 onward WRX requires a back section that is about 1" longer in overall length as they changed the exhaust slightly. Hence if I want something that does not require spacers etc and just fits I have a reduced choice.

Seemingly a Supersprint a Peco or a Magnex... or I could have a custom one made up.

I am after a warm rich flat 4 burble not interested in shear decibels and I don't want anything raspy or harsh.

Any thoughts?

(PS sorry if I am asking a done to death question, I am kinda new here and not seen anything covering this yet.)

Thanks Killa, Assuming yours is still for sale then

I've heard a RaceBox on an '06 Spec D, sounded very nice yet still very subtle.

Don't know about it fitting a '06 but I recently got a ScoobyWorld Ninja that is louder and fits your sound criteria...

Have got a Hayward & Scott Classic design b/box and centre section on my MY03 WRX and it's truly a thing of beauty!

Got an 04/05 Prodrive backbox on my 06 and its fits fine so not sure if you are limited at all, it does not stick out that far from the bumper though so is quite subtle, I can dig out a pic if you want, also sounds great with a deresonated centre section, which you'll want if you have a 2.5 56!

Consider the Vortex afterburner.

I had an 06 WRX and fitted a second hand Prodrive box from an older scoob, 03 I think, sounded nice and fitted easily. I now have an 04 sti with full Prodrive and resonator removed and it sounds great IMHO.

Changing the centre pipe for a deresonated one is essential on a hawkeye. Makes a big difference regardless of the backbox you choose.

Get yourself an unwanted STi BB from someone that has 'upgraded' their back box. Can be had for as little as £50. Then get a straight through centre section currently £70 I think on the H&S group buy.

View my scooby for sound. I have the additonal Sports cat and rear de-cat pipe, you might also consider fitting the latter. This is the only part that needs to be longer than the pre MY06 WRX's as the down pipe on these cars is shorter.
