Hey from over the pond in Scotland!
Ive had my 370 for around a year and I'm looking to get more sound from the exhaust.
i initially took out the mid silencers which made the car sound great. then i added berks hfc and the car exhaust tone was marmite. a lot of people loved it and said it sounded like an italian sports car. i liked it but after a while it was a bit too loud.
so now i put both id silencers back in and i still have the hfc but the cars now silent! its going back in to get one mid silencer out lol.

anyways i just came across this x mod and mid pipe and this may be the way forward for me since i like the stock tone but its just too quiet!
what is the washer mod that people are talking about? I've seen videos of it but not actually figured out what the mod is.

many thanks
