Is there a tune to make the 2.0 GDI exhaust pop and crackle?

I have a 2014 focus k&n filter, air filter lid delete, snorkel delete, muffler delete

I can hear the exhuast pop and crackle once in a while, in specific situations. im sure if a bit of fuel were to be dumped during deceleration id hear more pops and crackles hence my question.

is there a cheap chip tune or do you need to have a tuner like SCT?
Sorry ive never done any tuning before Thanks [thumb]

Exhaust helps if you have a header which removes cat and free flow exhaust (non chambered just resonated)..crackle is more of a FI thing but pops definitley

Gotta say it, that's a hangover from OLD carbureted cars that weren't working as well as they could back in the day. No good way avail. at the time for a performance carburetor setup to do a fuel cutoff that was adequate.

STOCK cars had that added in for emissions, and the pops & crackles went away for the most part.

But now it's kinda like when someone had a 'lope' tune avail. to make one sound a BIT like a race cam idling poorly. Tom didn't want to do that type of tune because it wasn't good for the car, and when something breaks the Tuner gets blamed.

IF you had a track car without a CAT (illegal in most racing classes now for Sports cars) THEN it would be kinda OK to do - but STILL not great for it.

catless and going with a header will help you hear any of those extra noises better... I could get some light burbles when i had my FSwerks header on the car, none since taking it off

When I decellerate, I get lots of popping (almost typed pooping!), so much its even a bit much sometimes, hahaha
