My milltek system on the centre section between downpipe and non-resonated pipe has a perforated lining in the exhaust at the front were it meets the downpipe but hasnt at the rear of that section. if i removed the welds do you reckon it will slide out with a little persuation ?? and also will it make any more noise and aid flow a bit better ?? just curious as thinking of removing it to see if i can change the exhaust tone as im a bit bored of the noise it makes at the minute it seems to quiet for a non res system wether its just because i drive it and never actually hear it fly past on full wot !!
