Replacing exhaust - what bits do I need?

[bmm]

I'm looking to replace the exhaust on my 87 Mk2, but I'm getting confused when it comes to what bits to buy...  I'm after the supersprint twin pipe jobby here:

Do I need to get the front and middle pipes as well as the back box?  I'm going to get my local garage to fit it all for me because I'm a dunce, and the downpipe needs replacing at the same time, but I just want to make sure I'm getting the right stuff!

Cheers.

Fortunately Supersprint components are compatible with VW stuff. I had the straight supersprint front pipe, supersprint silencer in the middle and supersprint back box, but also had a complete VW system with a supersprint backbox and a supersprint system with a VW backbox.

If you plan on getting everything pictured above then it will be quite loud

Uh oh!  Is it farty, baked-bean tin loud or only when I mash on the loud pedal?

Wanted to get away from the current exhaust that drones on the motorway and does my head in!

If you use a rear silencer over the rear beam rather than a "straight-through" pipe then it'll be fine on the motorway. They sound more or less standard at low revs, but if you boot it then they really come alive
