Does anyone how if a decat exhaust with shotgun is over 105db?

i fitted a 3 inch turbo back with decat no silencer to speak of until the back bazuka bit. It was so loud it lasted 2 days before it came off and sounded absolute plop! You would ping the sound test driving into the car park imo.
fit a decat silencer if i was you (which is what i did and was still around 98db)
I only ask as I'm running 3" decat with shotgun and 105 is the noise limit for skidding. Might have to get a silencer put in then

I'd imagine it would fail, nur specs have been known to be around that level I think and they have a silencer

i ran 3" turbo back to shot gun tips. not a single silencer in it. read 102db at Cadwell park static at around 3.5k rpm. obviously its much louder under load when driving but i wasn't pulled into the pits and told off. also ran it on the ring and again wasn't told off at all. i got it done with a vband join just before the backbox/tips and also had a quieter backbox made up (approx 90db) so i could swap them over in a couple mins without having to faff about with gaskets etc.
Might be able to get away with bungs then and just deal with the slight performance loss. See what happens

It's going to sound like someone farting through a megaphone...
I've had this system for years and never thought about changing it. Like how it sounds and looks miles better then the usual jap can everyone goes for
