hi shaun, there are plenty of exhausts, pick up a copy of PVW or Golf + and look at the ads, recommended brands for the mk3 are Milltek (quiet + quality), Jetex (decent), Scorpian (loud), many more. I wouldn't bother too much with a chip as it won't add much, maybe 3-5bhp, but it'll smooth out the power band. Cheap chips off eBay for £30-50 with standard performance maps, or a custom chip from someone like AMD, Revo, Custom Codes might do the mk3 ABF engine still.
