can anyone tell me if I fit a wr sport back box to the above , will it sound well (burble) and will it add performance or is it better going for a scoobysport or simular ?

 

Fitted a Scoobysport BB to the other half's 03 WRX, I have fitted a TSL Group N to my STi8. I preffer the TSL, if your dealer is **** about these things then fit a WR Sport BB, if not TSL is a nice BB.

 

cheers for that !

 

I had the TSL backbox on my MY02 & is amazing. Not too intrusive & looks the biz.

However, i was after more noise so i moved on to the HKS HYPER. Havnt looked back since

Why do you prefer the TSL BB over the Scoobysport one?

The BB looks better as I think they have got the size just right (4", Scoobysport is 3.5"), I have the center section as well so until we get her cars center section done I will not be able to do an exact comparision but the TSL sound nice and burbly and not raspy like some can.

Plus I get nice pops etc from it which is always a bonus, the exhaust is also not boomy at all when crusing at speed but put the foot down and it sounds fantastic.
