A decent sounding box required.
About £100.

 

I've got a complete exhaust with Prodrive backbox but it'll cost you more than a ton!

 

How much and where are you.

 

I'm in the Wembley area.
Have no idea what to charge so make a sensible offer.
The system had covered no more than 10,000 miles.
Anyone reading this thread have an idea?
I also have a Ramair filter if you want it.

 

I have an STi Backbox covered around 15k, not the greatest noise but looks quite nice.
