exhausts?

[afcbadam]

im looking a few exhausts i want a performance stainless steel jobbie but dont want a loud one i just want one thats the same level of noise as the standard one and isnt noisy on the motor way. any ideas or is it better to get one custom made to my taste. also noticed the bonnet isnt a tight shut. i lifts slightly while driving and can be moved when you grab the bottom of it. ive tryed to open it when stut and you cant so its not that bad and prob wont fly up when driving. is there an adjustment or could my catch be loose or something. chears guys
