J-Pipe question

[kmarshall2121]

are the ends plugged? i would assume so, since they just point towards each other... I want to give some specs to my exhaust guy to make, any input would be appreciated... Thanks

I had terrible drone with my LS3. I found a chart on the internet that gave recommended J-Pipe lengths for drone at certain RPMs. I had a shop bend up a set and weld them on. They made caps for the open end that could slide in or out a few inches. Based on the chart, I had the ends clamped at 29".

No more drone. Don't hesitate to get them, they work. I'll look for the chart.

I believe this is the thread above commenter was talking about. I just read up on it yesterday as I'm planning on doing this to my car. I have to MRTv2 axle back system and it drones really bad from 1750 to ~2100.
