i have a decat pipe, which, as i cant seem to find a buyer for am probably going to refit. What i need to do though, is make the thing quieter! So i have a few questions, can i just fit a bigger/more effiecient centre silencer? (all i have at the moment is basically a staight through pipe) if that will work, will it be detrimental to the performance increase i'll get by fitting the decat? and can anyone recomend anywhere that does custom exhuasts in the stourbridge/dudley area (not energized or LTC)?
