Exhaust Sound Comparison Videos
It seems that a great deal of threads are aimed at trying to figure out what exhaust systems and/or mods sound good.
Part of the reason is that most j-series exhaust systems don't really sound good at all. Another part of the reason is that
"good" is somewhat subjective. But most people would agree that drone is not good and unfortunately nearly all high performance
exhaust systems exhibit drone. This is because most manufacturers don't know enough about acoustics and perhaps don't care
enough to put the engineering effort into the design. Whatever the case, I wanted to start a thread to encourage a better method
of comparing j-series exhaust sound. The idea here is to show what an exhaust system sounds like under load. I've seen many
people post videos of just revving their engine. This doesn't give a true sense of what the exhaust system sounds like. I'm going
to set an example by posting two videos and hopefully others will follow suit. The first video is an interior acceleration run. The
second video is a dyno pull as experienced from the rear. The third video is an acceleration run with camera mounted outside,
but the wind noise becomes overwhelming and so isn't very useful.
Notes on the engine/exhaust system:
J37A2, stock except for a custom short ram intake
Custom j-pipe with 2.25" primaries and 3" main tube
Custom 3" mid-pipe with one custom resonator and splitting into dual 2.25" tubes
Proprietary and patent pending mufflers that are straight thru and completely eliminate drone

I have a similar setup to yours and believe that the 3" midpipe has a lot to do with the tone of the sound. I noticed a significant difference in pitch after switching from a setup with a 2.5" midpipe to a 3". Current setup is 2.25" RV6 PCD's off the head down to an ATLP V2-R Jpipe with 2.25" primaries collecting together into one 3". Continues 3" til they split out back at the mufflers with one 2.25" to each. No resonators or cats. It does have a "rumble" about it inside the cabin that can make it sound quite loud but I believe from outside it does sound good if not also very loud. This was back when I was N/A. FBO J35A8, tuned by Dom. Second video is same exhaust setup, but with forced induction and E85 (some people have said E85 makes it louder, I have no way of verifying this.)

Regarding the engine itself, I think all J-series engines with single port heads sound about the same,
with the exception of the dual vtec heads on the J37A2 and J37A4 sounding slightly more aggressive.

I’d be interested in hearing a set up similiar to:
Stock exhaust
Aftermarket J-Pipe
Mid-Muffler delete
Maybe HFPC or PCDs?
I don’t necessarily care about the performance increase, or dropping $1000 on a system. But would be interested in getting a nice tone out of the stock exhaust.

New dyno pull video with the latest j-pipe design. It sounds slightly better at high RPM.

Here ya go. This is mine on a Dynojet a few years back. I still have the same exhaust setup and love it. RV6 v3 jpipe> OEM resonator> MM delete> magnaflow 11365s

After looking at quite a few vids on Youtube, I'm leaning at either J-Pipe (whichever brand) > Dynomax res > MM delete > Magnaflow exausts, or for something a bit louder Res delete > MM delete > Magnaflow exhausts (maybe j-pipe too depending on loudness of the rest).
Any input on this would be welcomed if someone on the board did either of these. Like what it's like on a daily basis, rasp or drone if any, though doesn't seem bad from vids. The Magnaflows seems to reduce the rasp quite a bit if there is any. Any comment welcomed.
A few examples of the vids I liked:
XLR8 v1 jpipe, test pipe, stock resonator (though mine would be Dynomax), mid muffler delete, Magnaflow 11365 mufflers
RV6 j-pipe, resonator delete, mid muffler delete, Magnaflow 11365 mufflers

I just checked and for some reason (or I am blind) my video link didn't get posted on here:
Most people post XLR8, ATLP, RV6 set-ups but I rarely seen a wide variety of EndlessRPM setups. I am going to be the guinea pig for running the RV6 PCDs on an EndlessRPM setup.

Nice!
I have to chuckle... seems like you did a number of hole shots on a road that appears to be somewhat suburban. I hope nobody called the cops.
Also, either your clutch is slipping a bit, or you haven't removed the check valve from the slave cylinder yet.

The check valve in the slave cylinder is intended to protect the drivetrain in case the driver is abusive or doesn't know how to properly shift.
It's commonly used in many clutch systems, especially for higher torque applications like trucks with diesel engines.
As long as you don't rev the engine and drop the clutch from a dead dig, then your fine. People generally don't do that with these cars anyway
due to the limited traction with FWD and the tendency to wheel hop. Your clutch engagement will be faster and more precise without the check valve.

Yeah, dumping the clutch from a dead dig is very hard on the gears, differential and axles. And it's not the quickest way to launch either.
10-28-2019, 11:35 PM

I figured. My friend who at times I feel like he doesn't know what he is talking about, kept saying my method of launch is bad for my clutch (slip-launching) and said I should straight-up dump it. I keep telling him I would rather replace a clutch than to replace parts within my transmission and he still acts all confused and everything like I am talking nonsense. And I agree, clutch-dump launches do not feel fast at all.

Launching isn't bad unless you have wheel hop. The repeated slip/grab of the tires is like a jack-hammer on your drivetrain.

It really does. Like the rasp is well contained (actually none at all). It is perfect.

Hey man, no I haven't. I am going to lay off from bolt-on mods like RV6 PCD and focus on acquiring all of the discontinued A-SPEC parts. I am probably going to pull the trigger sometime in the spring-summer season.

I hear you bro. Yeah the A-Specs are hard to find I gave up on that. Everyone bought them already lol. The right time will come when someone is selling it for cheap. Another question, did you notice any increase from swapping your previous Jpipe to the Endless?

Does anyone have a setup that is straight pipe from the jpipe back? Or straight from the j to oem/aftermarket mufflers? Curious, because I will end up with one of these 2 routes on Saturday.

I did a 2nd gear pull from an highway onramp and the acceleration pretty much pushed me into the seat. Not sure if this matters but I kept up with a 2013 440i from a 3rd gear pull at about 90km/h start but then the top end of that Beemer blew me away completely as I shifted into 4th.I can see why the J-Pipe and RV6 PCDs are important power mods for our J-series platform! Also for sound too 😉

Yes I noticed it after 2 weeks of driving it. The initial week I did not notice much but as time went on, the exhaust note got way throatier.

You're definitely slipping that clutch in 2nd. Still possible to get it smooth without removal of the CDV, although will have a vague engagement point which is why you seem to be riding the clutch.
