So apparently the drone from my Borla straight through/packed lers is exactly the same as the Flowmasters they replaced. Anyone have any ideas on getting rid of it? I'm about ready to test the "theory" over at Corral on welding 2 foot long pipes onto the tailpipes to change the resonant frequencies. Any ideas on anything else I can try prior to doing this? I've also heard of going to larger tips helping cut down on exhaust drone.
It's that 1700-2000 rpm range around 130Hz (slightly lower than on Mustangs). I guess the easy way around it would have been a single exhaust :p
As you probably know from the Corral thread, I put Corsa lers on mine for the drone - they did squat. Resonator type exhaust tips help some, obviously the resonator tubes will work if you want to go to that extreme.
If you've got the resources and ability to make those, do it and let us know the results!!!!
Yet another reason I love my 3.73s......above that rpm on the highway lol :hick:
Hah, yeah, that sounds like it was a waste. I may just go that far to try getting rid of the noise - it drives me nuts. It's annoying around town too unless I get on it, let off, and get on it some more to keep the motor out of that rpm range. It grabs around 2200 rpm's with this stall converter.
