Is the standard one very restrictive?
Would I gain much power increase simply by changing the backbox?

I put a Group N on from TSL to replace the standard STI B/B, i must admit the car does feel a little more responsive, and the noise is awesome at hard acceleration!!!!

I replaced my rear box and resonator section with Miltek parts, cost about £280 from Roadrunnner, Nottingham.

They can fit it too.

Made quite a difference performance wise, but a bit loader than the Magnex I had on an ealier MY00.

Awesome looking tailpipe 4 1/2" round stainless, slash cut.

How about fitting a Prodrive Pension Plan ? Assuming it's a UK STi7 ?

Got one on mine and it burbles very nicely (could be the passenger as well but once I tightened the seatbelt that goes away )

I didn't particularly wanna spend £2k at the mo, was hoping that a few hundred quid on just a back box would provide a nice sound and a bit extra poke, plus can be swapped back for warranty issues.
Just wondered if a back box on its own is worth the dosh.
