I have a 1.8T jetta that I had the exhaust done on. I did a header and had the whole thing straight-piped back with 2.5" aluminized pipe into cherry bomb glass pack. Trust me, if you take long trips it will annoy you to no end, but around town it is sweet...especially hitting a high rev down shift and hearing it crackle lol. My buddy straight piped his 02 Ford Focus and it's not too loud, but its noticable.
