Pop, Bang and Burble

[elmo2002]

I no this sounds stupid but why do some clio cups i see pop bang and burble yet mine does not?

 

[Inferno]

Different exhaust systems is my bet.

 

[Bazzon]

Decat-ed probably.

 

[elmo2002]

well mine's both de catted and with a after market exhaust. Would it matter if the de cat is silenced or not?

 

[Bazzon]

Sure the other cups were standard engine wise?

ITBs spit flames and so to do cars with bad mapping where the fuel to air ratios are wrong

 

[elmo2002]

Yea quite sure, seen loads of sports up castle combe that are all standard engines like it.

 

[Puressence]

my car was running too rich when mine use to do it before i had it re-mapped

 

[Dafthead]

Maybe it does but you can't hear it from the inside?
