This is great to hear. Ever since I put a Magnaflow on my 4runner it has a ton of drone at 1500 RPMs and its been annoying as crap. I just got my measurement for a Jpipe to cancel out the appropriate hertz and will be adding the jpipe next week. Can't wait to hear the difference.
Hey everyone, I'm a total noob, how exactly do they measure for a j pipe? Do I have to tell them the speed and rpm I get drone at? Does that figure into the measurements?
I disagree with the statement "the longer the pipe the less drone". The channels "Alex Cieplutch" and "Lawrence LT Tolman" have good videos about it with charts depending on your engine's number of cylinders and what rpm you wanna eliminate drone at. Doubling the lengths on their charts could maybe widen the range of RPMs to eliminate drone at, but if you want a better chance of getting best results, I'd check those out.
I take great pleasure in knowing that the annoyingly loud cars you guys spent tons of money on to make them loud, are equally annoying to the owners/drivers.
