help vn poping and cracking??

[hellbound]

i started my car today after doing a trans swap and it started to pop??? what is this or what could it be??

My first thought is that it may be doing this when you back off the throttle? Perhaps an exhaust flange isn't sealing properly.

I have no idea what you mean though, so that's just a guess. Maybe you left a bag of popcorn down there?

i remembered my old shitty magna crackled and popped under deceleration cause it had a hole in the exhaust at the front. Before then it didnt

ok there is no hole in the exhaust and my extractors are all put on right. what else could it be? it sounds like its back firing

have you got your firing order right? lol done that one before makes it pop and shit really weirdly. Then again i'm sure not everyone is as dumb as me haha.

To be honest by your description it could be hundreds of things, really need to have a listen to know what you're actually talking about
