Evening All,

I'm thinking of getting a Ninja 1 back box for my Impreza from Scoobyworld.
Will this be enough for improved noise, growl or will I have to cat back?

Thanks

 

it will improve the noise but a cat back would be better all round

 

changing the backbox will increase the noise but a cat back will sound much better (decat that is)

 

I have the same Exhaust Mate. Defo tell in my opinion! 1st got the Back Box, then the After Burner Centre Section, still wanted more Deeper Sound so i Got the After Burner Cat pipe all from Scoobyworld. Sounds Great now, need the Decat and a Remap next. Skint though! Here's a clip of mine if it helps:
