Well... Sounds like it caught cold... try thermaflu?


jk... Man I dont know what it could be possible because the car hasn't reach the right temps?

Just F Me

no idea here either...maybe it's just cold and it's backfiring a bit?

Can't really help without hearing clips of the exhaust sound

My car only pops (sometimes) when I slow down for a stop, not at consistent low RPMs.

Im curious to hear your setup, this is what I'm looking to get. Did you end up getting the HKS mid-pipe as well?

Is this the normal rasp headers add or something more sinister? If not, could you have an exhaust leak?

^^^This could be it too! I had a cracked exhaust manifold (header), and the car was very raspy at low rpms, when it was WOT, all the other noises drowned it .

Back fires off throttle popping sounds like exhaust leak.
