Why does my exhaust not crackle and pop anymore?

Probably not....however when ever your computer is updated it's also reset. It will take time for it to learn... if it was recent I would say it's that ... give it some time to learn..
I have the mppsk and some times my car doesn't snap crackle and pop if I nanny drive it for a while.... I beat on it some it comes back... the bitch needs a beating to snap her back into shape... slap her around some and see if she perks up... Another possibility is going from high flow to restriction putting back the cat.... the computer has adjusted probably radically..... maybe you need to reset it for it learn again (maybe the dealer did not reset the computer)... disconnect the batter for > 30 minutes ... reconnect and let it learn again using the proper motivation described above...

a theory:
the vehicle does not exactly run right the second you get your exhaust installed. from that point on, the ECU must slowly adjust fuel/ignition timing and "learn" your new exhaust. this means that the car could have been running a little too rich from the beggining and you hear fuel burning off as a result. once the ECU adjusts, sound is gone. I recommend getting a catted downpipe and putting your stock exhaust system back on. or if you still have the catless DP, put a high flow race cat somewhere in your system and then upgrade your axle-back if you want more sound. some sort of high flow cat will get rid of almost all the smell. if you smelled it often, it could have meant a gasket leak. I'm telling you this because if you want pops, you need to have as little cat restriction as possible. A catless downpipe with full exhaust system is way too loud for some tastes though. |

perhaps it points at something else? what is your current setup? downpipe with full exhaust system and no resonator must sound like ass lol. I'd recommend going back to your catless downpipe and keeping the rest of your exhaust system stock. the sound level should be perfect for you and you'll get some crackles. alternatively, upgrading your axle-back muffler to something high flow like remus with the downpipe will be loud, but the crackles will sound sick! as for why your exhaust doesnt crackle and your friends does? hard to say. there are a lot of different reasons why. try downshifting with all your windows down, no touching the throttle yet and listen carefully - you should hear some light burbling. it should crackle once you back off the throttle after aggressive revving as well. cheers! |

Thats weird man... my car will go into little episodes where it wont do the pops but it always comes back after a minute or so. Does it burble at all? or just no bangs?

My car won't do them until it is completely warmed up, so driving for a couple minutes

Hm thats weird. Maybe try leaving it in comfort and no high RPMs the entire warm up process and once its fully warmed up try some downshifts in sport. It usually takes a few to get her going though.

Mine always burbles. It's really noticeable in a parking garage, where every lift off the throttle bounces the burbles off the walls.
For me, the pops are broken up 2 ways: 1. The really loud singular or double "pop". The exhaust must be fully warmed up and I haven't done any high revs for a bit. 2. The quieter multiple "pops" are there around 4-5k RPMs. Definitely more of them although much quieter than a 6.5k RPM throttle lift off. I have the AWE catback if that makes a difference. No downpipe.

You have to put one cup of rice krispies in the gas tank after every maintenance.
Sorry I couldn't resist. |

What gas are you using? I have the mppsk and have noticed when i only use 91 octane it doesn't pop like it does when I use 93 or 94 octane.

Turn off dsc and hover in the 4-5k range and let off

I recently put in the jb+ and immediately noticed that I lost all my nice exhaust sounds. No pop, burble or bangs.
However, last few days have turned the dial on the jb+ to maximum and not only are the sounds back but now it's even louder and comes on more frequently than when the car was stock. Love it now! Just hope it remains this way. |
