Has anybody done this? My exhaust is a bit quiet (think silenced egg whisk), I don't want a loud stereotypical Saxo exhaust but would like a bit of burble to it. It's been suggested I chop the centre silencer out but I don't really want to shaft a perfectly good exhaust. Eventually I plan getting a local firm to build me a cat back system (not PowerShonk and not Miltek after reading a few bits on here ). Thought this might be a viable temporary fix. My brother is a handy welder so it won't cost anything to do.
