Hi Guys,
Very interesting Chris, Simpsons are suggesting a 6" can only about 18" long, i was concerned that it wouldn't be long enough to get the sound down, maybe them suggesting it goes in straight helps with that, i also think its to do with the end caps they use and the fact that they only come with holes in the middle!
At present, the last time i had a noise tested at Snetterton, it only just passed at 104db from memory, i think all the stuffing has gone:( I'm off to Castle Combe in may and they have 100db limit, so i need to get it sorted.
Mankee, the problem with the caterham ones are they are not repackable, so will be in the same situation in a year or two, i really wanted a repackable one made for that reason. At 360 quid for the caterham one its not much more to have one made.
cheers
Jon
