Thanks guys! greatly appreciate your help on this!! Ok so I have decided to go 3" dump pipe with high-flow metal cat and 3" custom cat back. Firstly, is there any issues with this set up that may be obvious? Will it affect my engine/turbo in a negative way at all or cause any future complications (other than defects for no muffler + noise pollution)? Please keep in mind I am not planning on doing any other tuning except a new panel filter + F6 snorkel - this is a work car so I have to keep it tidy. Secondly, will the sound be overbearing? I mean would it attract a lot of attention? I.e from police lol if anybody else has a similar set up I would be glad to hear from you!! Thirdly, what level of increase in performance is to be expected? And lastly, am I paying too much? Best price I could find was $1600 Sorry if these questions sound amateur I am just new to this all. Thanks for understanding! Cheers,
