Love it Tim. But calm down, I'm not 0-speed hump guy! I was just asking opinions! I will try the piper cross replacement filter I think based on your sound (albeit bit of a rant) advice.
If you take a look at my pic you'll see my car is quite original...
Thanks for your input though will not swap out the original box, any tips on making look a bit better though, ie cleaning it up? Things are looking pretty good under the bonnet as I've replaced a lot of pipes and parts recently.
