Exhaust Pops after installing headers

[ToasyNut]

Hey guys, I just installed some shorty headers and since then my exhaust has popped after accelerating quickly or revving. I just want to ask if this is normal or if I should be checking anything? I’ve read that an exhaust pop is usually due to too much fuel and/or not enough air. Thank you!

What exhaust gaskets did you use? A leak will often suck air into the pipes, adding oxygen to the hot fuel remnants, making pops and bangs.

Also, make sure you aren't running lean.

I just had a muffler shop seal up the y-pipe to the headers, though I am running straight out of the car right now, could that be causing the pops?

More likely leaks where the headers bolt to the engine.

WHAT VEHICLE? WHAT ENGINE?

Lack of exhaust system past the Y-pipe is a likely cause.

This was the issue! I unfortunately did not remove the tabs that hold onto the spark plugs which were interfering with the header flange and the engine. Stupid mistake on my part but you live and you learn, got some new gaskets and got it sealed up.
