with oulton park coming up in a few weeks and worried abvout the 105db limit, decided to ask my mate if he could modify the downpipe on my car and add a centre box. previously the wastegate was vented to the floor screamer pipe style. now its back into the downpipe.
its a bit quiter than it was before. sounds a fair bit different to drive actually.

Do you have an iphone or know anyone with one? Sure you can get a db meter on them
They take the reading parked up and you rev to 3/4s of your max RPM.

No idea how accurate they are but should give you an idea.
I think mine should be ok but id like to get it checked just in case. Trouble is i dont know anyone well enough with a reet posh iphone to ask them to hold it next to my exhaust

smoothest place to make it enter back into the downpipe. the first thought shorter version would have been 90 degree into downpipe at a 90 degree angle to the flow.
