Any solution to being over db on trackday

[beeds]

Hi guys i think i have a problem

i was looking to do my first trackday but came across the noise test and have thought that my car may be over it. My clio has a itg maganex cone and a ktec cat back exhaust

just wonder if anybody knows if this will fail the test an if so how can i make the car quieter to pass

Really depends on the db limit at the track, they're all different. Also will depend if it's a static test or a drive by test.

There are apps you can get that are fairly accurate (not 100% but will give you an idea). Some are free too.

I doubt it'll be over if you still have even one of the cats in place.

You could get a baffle to put into the exhaust to reduce noise. On the ktec website it stats the volume of the exhaust.

Ease off / short shift if it's drive by.

You should be fine with just a catback mate, I got through with mine straight piped and decatted.

Come and do our Sprint day at Curbourgh in May no noise tests

My 172 has no silencer at all bar the back box ? It has been decatted , and the mid box was blowing so I just cut it off got some steel pipe from a iron monger , and just spot welded the pipe I. , I run a huge induction cone and like u say just the back box mine was 92 db at a stationary db test at Caldwell , some tracks range from 97 db up to 105 a few do 95 but very very few tbh

Coke can, cut off the bottom and jubilee clip onto rear pipe

Mine static was 97 on just rear silencer. Day was 105 static.


Induction noise can be a killer espically on drive by
