I'm hoping his didn't work because he did not use 3" pipes to match his system, and it does not appear he used the Helmholtz chart.he was at 30", but complaining about 1800rpm drone (so i think he needs to shorten the j-pipes.
Does the j-pipe need to match the 3" pipes? In this picture they are using a much smaller size (but it didn't fixe the problem). Which raises a few more questions I have as I'm trying to design my own solutions.ġ. The picture helps, but unfortunately it did not help the person who posted it. Here's a photo from post #242 on this topic showing Flowmaster AT's with j-pipes:

I've seen some post that imply the CAI may resolve the drone? Doesn't make sense to me.should i wait to install my CAI prior to trying to resolve the drone?Īny expert recommendations? No need to recommend going back to the stock system. I also have a CAI (from CAI inc) w/scoop coming in the mail. One of the more knowledgable folks I talked to is recommending i install a Magnaflow dual 3" in/out muffler where the stock resonators used to be, of course that will quite it a bit, but he claims it will have no negative impact on performance. Does the j-pipe solution quite the sound? Or simply tune out the drone? Based on the Helmholtz chart, i would need a ~26" J-pipe.i'm not sure there is room under my car w/the American Thunder mufflers.the pictures on-line shows it with the Outlaw mufflers.
I called around town (Houston, TX), and haven't found anyone who has actually installed the J-pipe/Helmholtz solution. The other solution of course is 5th gear. I love the sound except on the highway when the drone kicks in at cruising speed (it goes away about 95mph ). I had a Flowmaster American Thunder 3" cat-back installed. I just bought my 2012 SS LS3 less than 2 weeks back. I'm new to this forum/Camaro's in general.
