Hi there

I have a mk5 fiesta flight and what to put a different exhaust, however i dont know where to start looking.
I would like something that isnt really loud but gives a nice grumble when my foot is down, also i dont what size would be best as i dont want a pipe cleaner exhaust or a dustbin sized one, i was think maybe up 3/3.5".
Any suggestions on manufacturers?
Regards
