I had a stainless exhaust made last year and just had the header plasma coated by Zircotec 'antique silver' colour. The pipes under the car look very similar to 4uall's but I'd like to see pictures of his header.

The 'naked' header.

Zircotec coating (with a weld 'scar' because a crack appeared just after it was coated - grrr)

Before the 131 'box was fitted.

I decided to keep with 2 silencers (mufflers) as I didn't want the noise to be overpowering on long drives.
A clip of me giving my Spider 'the beans' is in my signature area below. This gives you an idea of what a performance exhaust with 2 silencers sounds like.
