Does anyone know the structural difference between the 2020 SVR exhaust and the 2021 that makes it louder?

Planning on making the exhaust a bit louder on the 2021 SVR and wanted to try and get it to sound as close to the 2020 as possible. A resonator delete seems to be the easiest/most popular route to go but I was wondering if anyone can tell me if there’s a better way to get it to sound exactly like the 2020. I attached a pic of the current exhaust setup with resonator for comparison.

What causes the need for steps 4-6? What makes the valves partially close again, and when does that partial closure occur?

From what I can tell, the exhaust valves positions is determined by engine RPM and/or throttle position. Example, when idling, mostly shut so you don’t disturb your neighbors.
When throttle is wide open, exhaust valves are wide open, hence the great sound when accelerating hard.
If you don’t do steps 4-6, the exhaust valves will operate like they always have.
By doing steps 1-3 & steps 4-6, the exhaust valves will be in the open position all the time since there is no power to them to make them change.

are the burbles back with this like they were in the pre-facelift?

YUP. Big time. I think it’s louder and more fun than my 2020 - assuming the Pre-facelift had a little bit of logic to close the valves a tad in loud mode too sometimes.

that's great to hear ;-)

hope some one puts up a video for us to all enjoy

Just did this. Pretty easy, especially when you pop off the black splash plate underneath the rear "diffuser." Startup is LOUD. Excited to try it out on a drive. Will be nice to not have to push the exhaust button everytime I get in the car now.

I had done my 2021 about 6 months back and ran that way for a month or two before I had to reversed it when I took it in for service a month or two back. I just disconnected it again as I got complacent with the car being so quiet. It's nice to have the noise on start up and the burble, especially when in sport with the Transmission. I still put it in dynamic since I really like the suspension settings there. So my sequence is this now on startup.

1. Hit the gear button on the screen and turn off Auto Start Stop.
2. turn the knob to go to Dynamic.

I had found out a way to defeat Auto Start Stop all the time by pulling a cable off the battery under the spare, actually posted here on that. Doing that also ended up stopping the Heated seats and wheel from working. Didn't use them when it was warm out when I original defeated Auto Start stop and was stumped why they weren't working when it got colder but as soon as I reconnected the cable to take it into the dealership since I wanted an oil change at 8k miles. Planning to get this SVR probably forever if it continues to run well.

I was just out for a drive and I'm not sure the exhaust is much louder at the top end. But definitely notice more burbles and noise at the lower RPMs. Honestly, Jaguar did a pretty good job with the exhaust programming. But I'm going to keep it like this so I don't have to push the exhaust button every single time.

Does the auto stop/start frequently activate for you? I have found that with a very light touch on the brake pedal, it doesn't activate. I can't even remember the last time it shut down on me. Maybe 3-4 times total in almost a year of ownership.

Yes, much of the driving I do is city driving during the summer down in our seaside down. 25 mph speed limits, lots of stop signs and lights. It's constantly activiating and isn't off long before I start to lift and it starts back up. Kind of annoys me that it stops just when I'm about to start. So I simply got in the habit of hitting the gear button when starting the thing. I did the defeat which existed before the 2021s on both my 2017 and my 2019 SVR. Got so used to it not happening.

that's weird that my experience is quite different. my commute is also stop and go, suburban streets. and it essentially never activates. our vehicles must be calibrated differently? although this is software so that doesn't seem to make sense.

Mine kicks in almost every stoplight. I almost never get it at a stop sign unless the traffic on the cross street is heavy and they do not need to stop. I think I need to be stationary for about 5 seconds or so for it to kick in. I can cause it to not activate by lifting a little off the brake a bit, while at a light, not enough to roll forward, but that becomes a hassle so I typically hit the gear icon and deactivate it.

Before proceeding, make sure tailpipes are cooled off.

1. Push start button without pushing the brake pedal. This turns the ignition on, but does not start the engine.
2. Push the exhaust button in the center console and this will open the exhaust valves wide open.
3. Look into the end of the tailpipes with a flash and confirm the valves are in the wide open position.
4. Crawl under the car and disconnect the connector from the exhaust valves. To do this you need to pull back on the Red tab and then push down on the Black tab and slide connector off of the exhaust valves (see pictures in my previous post).
5. Now start the engine.
6. Look into the end of the tailpipes with a flash light and see the valves in the wide open position.
7. Enjoy the louder sound.

Note: With the engine off, I would recommend sealing the connectors and connection on the exhaust valves so they don’t get corroded and securing them away from the tailpipes so they don’t get against the tailpipes.

Do you recommend resonator delete with straight pipes and valve open would make the car even better? Thanks in advance

Hello
Thank you for this guide
how you sealed the connectors? with shrink tube or something else?

Hello, All. I was just searching the net about making the exhaust louder and found this thread. I then found another thread that note perhaps an easier way to disconnect the valve connectors from the spare tire area inside the trunk. It‘s on the F-pace forum uk site. I currently have wife’s 2021 F-pace R-dynamic but have an SVR F-pace on order for myself that is coming in the middle of next month. It looks like one can just disconnect the pink plug by the spare wheel to achieve the same effect after doing the accessory mode procedure. This way, one wouldn’t have to be concerned with taping up with electrical tape and temporarily sealing off the connectors under the car. I definitely plan on doing this once mine comes in.

I don’t think there’s any structural difference between the 2020 SVR & the 2021 SVR. The it’s not as loud is Jaguar changed how valves in the tail pipes are positioned via software. Try my suggestion below and let me know your thoughts.

Before proceeding, make sure tailpipes are cooled off.

1. Push start button without pushing the brake pedal. This turns the ignition on, but does not start the engine.
2. Push the exhaust button in the center console and this will open the exhaust valves wide open.
3. Look into the end of the tailpipes with a flash and confirm the valves are in the wide open position.
4. Crawl under the car and disconnect the connector from the exhaust valves. To do this you need to pull back on the Red tab and then push down on the Black tab and slide connector off of the exhaust valves (see pictures in my previous post).

I just want to put this out there for anyone that is planning or already did this.

be wary of unplugging the exhaust and keeping it like that for quite a while. I’ve done it the original way(from under the car) and I loved it, however, keep an eye on your oil level (via.Vehicle settings-service information). I’ve had to go to the dealer 3 times now because of oil fill-ups and a check engine light one time. The service manager said the oil issue (roughly 2L overall top-up) is most likely because of the exhaust mod. And also he said because the valves never close, it could cause problems and use excess oil because there is no “back-pressure”(something like that). IMO, even if that's the case, I don't think it'd be using that much oil

Check engine light was due to a faulty oxygen sensor. ( I believe it’s because of the mass amount of pops and bang/burbles I do 😂).

Everything was covered under warranty btw

following.. I think my exhaust has been unplugged for 8+ months at least and I haven't had any trouble that I know of. vehicle also went in for a full service with the exhaust unplugged and no issues mentioned. I can't imagine a valved exhaust affecting oil consumption.. if anything I would think INCREASED back pressure would increase oil consumption.

don't seem to be any issues in my vehicle. just checked the oil level. last service was in March/April.
