So, anyone having this issue with there Flowmaster Axle back Force II exhaust mufflers. Just a few days ago I had my headers and off road x pipe installed and very happy. I have the Flowmaster Axle back Force II exhaust system for the past year and half and like them. One thing I noticed prior to the headers was when reving engine or flooring pedal the Flowmaster mufflers would make a crackling, popping sound. Kind of ricer sound but not as bad. Even after the headers and off road x pipe were on I noticed the exhaust was much louder of course but the mufflers would crackle louder when reving engine. The crackle would be very high pitched when you let your foot off the pedal and the air was being sucked back into the mufflers
Today, I stopped at the muffler shop where they installed my Flowmasters. I told the shop owner I was interested in having resonators installed so I could have the exhaust tone more low pitched, deeper tone and way less crackle and ricer sound from the mufflers.
The shop owner had me rev the engine several times and like clockwork as the air was being sucked back into the mufflers they were crackling like crazy. The shop owner laughed and as nicely he could be, said the mufflers sounded ricer and the tone was horrible. The shop owner further stated that crackle, popping sound was being made by the Flowmaster mufflers and had nothing to do with the headers, off road x pipe. The shop owner advised having resonators installed was not going to change the mufflers from cracking because the tone and cracking was because of the mufflers.
After looking more into this exhaust system he noticed the tips were extremely filed with heavy condensation inside the tips. He also noticed when reving the car the mufflers were spitting heavy amounts of water. He showed me and the mufflers were spitting water out like crazy when reving the engine.
The shop owner said there was my issue with the crackling. The tips on this Flowmaster axle back Force II system are very thick, and they are holding large amounts of condensation. Shop owner was claiming the sound was bouncing off the very thick tip along with the water on them and that's the cracking sound, all that condensation on the tips.
Shop owner then removed the tips and told me to rev the engine several times. Wow. Holy ***** . No crackle or pop. The exhaust sounded loud but much deeper and no crackle. The shop owner told me get different and better tips.
He also noticed that my Flowmaster mufflers did not have a small hole drilled in the underside so there was no where for the water in the baffles to escape to. He recommended that I drill a small hole in the muffler that would allow the water to drain out when the water is being sucked back down the muffles when the car is not accelerating. Shop owner said the condensation was the biggest issue when it came to the crackle sound.
Now the tips are off , no more crackle but need tips that are not as big and thick as the ones that come with the system. Any recommendations on tip that won't hold condensation? I'm still planing on getting glass pack resonators to help with the tone and pitch from the off road x pipe but what a difference with the tips off.
