Thanks for doing this Andrew, I have a feeling it's not going to work very well on my temporarily stock exhaust setup... or will it?

Update: Works fine after you get the pedal feel right. Popcorn on demand

just did this to mine, i have the Borla UEL header, factory overpipe, factory front pipe, vibrant muffler, factory muffler delete.....

below 4500rpm, it sounds like intermittent popcorn popping in the microwave....above 5000rpm.....yea lol..... it sounds like someone shooting a gun at times....super loud! i will try to take a video one day and have someone following me recording cause it sounds like there would be fireball pops being how loud it pops at times above 5K rpm =)

Hrmm I made the changes and got nothing. I do have a catted header though?

i dont know if this is what your doing but reving the engine in neutral didnt really cause much backfiring, its when i was driving, rpm hovering around said RPM, feathering the gas pedal is what caused the poping

stay on the gas just a bit when letting it rev back down and that will give it the extra fuel. There seems to be a sweet spot that gets the correct fuel in the exhaust. My headers cat has gone missing though.

The next tuning adventure should be to find out if we can get ghost cams at idle...

Prove it!

Haha Yea I should get a video with the GoPro. Went on a rally today so I will see if anyone got some clips.

Proof... did it take a while for the popping to begin? I made the changes in RomRaider and just barely notice it.
