Having issues with popping sound in exhaust. It will back fire sometimes when you rev it up and let off gas. I check plugs and they look good. Had friend put rags over tailpipes and I checked for leaks and there were no major leaks. I thought that my offroad pipe might be doing it, but I replaced it with stock pipe with cats and it still does it. What could be causing this and how can I fix it?
Stock motor with larger injectors for TT. This happens when the car is not under boost...
Thats normal for these cars. My exhaust pops when I let off the gas sometimes, especially when the car is still cold. Once the car warms up a bit the popping is minimal.

Its probably the TT setup. If you really are worried about it feel fre to ship the whole kit to me for testing/proper disposal.
But ya, my gt pops a good bit too. Normally when the rpms are dropping after a healthy rev. Definitely worse when cold too. not a big deal, some mufflers are known to pop alot more then others
