im not sure this is actually not a normal sound with out cats but I do sure know it worst when im rolling and flooring or down shifting, there is way more bra-pa-pa that can be hear, just cant make that clip too much wind etc.
Believe it or not all cars would do this without mufflers or cats, its a normal sound the above are made to cancel them out. I LOVE when you downshift and it pops like that.
Moose, this is a video when car is hot, i know at 100% sure that the back fire sequence from no where is not normal on cold start, but the wide band is telling me that im really lean on cold start, my tuner will send more fuel with the pcm on start, hopefully this will fix it. I just wanted to make sure if it normal what im hearing when reving downshifting etc, im actually going for a pair of reasonator. Just not sure where can i put them..xpipe?

It stay lean, the mix get perfect on hard acceleration n etc but lean on low rpm cruising. I do not have the exact number cuz my wide band o2 do not work, had to test it on the dyno
