Best Place to buy M Performance Exhaust for E92 M3?

[JKay]

Hello All

Whats the best place to get an M Performance exhaust from within the UK?

I have looked in the US and found Tischer BMW who do them for around USD$3,500 (2,150 GBP) plus delivery to the UK. Is there anywhere in the UK that does better than that or is this sounding like the better option price wise? I believe in the UK they go for 2,500.00 GBP (USD$ 4,065.50) supplied?

Thanks in advance
