K, so I was talking to vital on AIM, and we got in an excellent conversation about exhaust. And I need answers
After putting a flowmaster on my bonneville, and a magnaflow on the Cav, both cars had popping noises from the exhaust. Not only are these sounds normal, I actually find them to be quite pleasureful to my ears. These popping noises are very noticible on the cavalier when I use engine braking from 3000 RPMs to 2500 RPM.
We concluded that these noises always existed on the car, but the OEM muffler always muffled them. Due to the different baffle design of the aftermarket muffler, they are now audible out of the exhaust.
Now for the question: what is causing the popping? Is it unburnt fuel hitting the cat converter? Or are we way off? (Note: Vital neither confirmed or denied this, this was all my idea. If its wrong I don't want him to look bad lol)
