i recently had the exhaust done on th 08... now at wot, when it shifts it makes this really loud (most of all embarassing) pop/sputter. it sounds to me like the ecu is cutting out to make a smoother shift? is that correct? is there anyway to get rig of it. i cant stand to get on the throttle any more because every shift sounds like the engine just exploded.

 

You need a tune now. its unburned fuel. what type exhaust, performance?

 

i will try to make a clip as soon as i can, it sounds like a massive missfire

 

the exhaust it 3in, from the y-pipe and a round magnaflow

 

IMO its tune time.

 

Going to a 3 in exhaust shouldnt have made that big of a difference where a special tune of any sort is needed. Hell I have the same set up and mines not popping or missing.

 

Like this?

its not like the one in the video... only does it @ full throttle, under power, while its shifting, i will get a video this evening.

 

mines done that since the day i put my magnaflow cat back on, i think its the auto trans, any modded auto truck, hemi or 4.7L I've driven at work seems to make the same sound.
Just at wot when it shifts and I agree, it sound lame lol
