Looking for a new exhaust

[Matt]

I want something new. 

I currently have an decat (empty cat) straight through centre section, to an empty backbox. 
Sounds mental mental, I love it, but think I'm getting old and want a change. 

Anyone recommend anything? Any like to videos? 

I've had a magnex decat with a powerflow cat back it sounded the tits so wouldn't mind something similar, does anyone have anything for sale?
