Thank you for correcting me on the price for the TRIDENT. I was going based off of a google search which converted the £399 GBP into $800 USD. According to google the exchange rate at the time of this post was 1GBP=2.00057USD. Here is a link to the IXIL exhaust which you can buy from there website for £274 GBP.
