I didn’t like the tinny sound of the resonator delete and so I had my muffler guy do a custom pipe from the resonators back. I’ll post a photo in a reply.

Here’s a sound clip..if anyone has specific questions let me know.

It’s a little louder than a 392 Scat Pack Challenger, and about the same as a stock Gallardo.

It’s fairly loud. I’ll post some cold starts and cruising tomorrow.

It’s loud enough to scare our Maltipom going under bridges hah.

^^^ That IS loud! That would vibrate the house for sure. So BEASTLY! I love it. But my wife and neighbors would not approve. Thank you very much for showing us this. I appreciate it.

Yeah it is. I probably won't do it on my new RR. The fiance will be getting a 3.0 RRS and I'll be getting a 5.0 FFRR.. it wouldn't be right on either. My neighbour was video taping me leaving my property one day and I slowed it down after that. It gets quite loud above 3,500RPM and half throttle.

It's chaos when I have it in the garage and the door closed...and I do that if it is at night/early morning due to said neighbours.

Well it sure sounds **** good. I just got the 2020 sport P525 and I dig it so far. But we do wish it was a smidge louder. I might try sport cats.

Thank you for sharing all this and answering questions.

I heard sport cats can cause some issues.. may want to get just the cat back?

But I suppose talking to Stuart would be best bet. Removing the cats could cause issues with the Land Rover warranty.


Congrats on the purchase!

I just looked at this 2020 Autobiography Sport


And this 2016 Autobiography


And decided I’d like another L405..we bought this Sport for my fiancé after a failed attempt at owning an X5 and I kind of just stole it after I sold my 2017 L405.

So I just bought a 2014 sport 3.0L and I want to delete the muffler. But my concern is after I straight pipe, does the check engine light come on as the car doesn’t get enough oxygen (sensors)? Reason being, I’ve done this before with my dodge and the check engine light did come on after the muffler was deleted

No you won’t have any CELs (check engine lights) especially with an axle back system.
I went cat back quicksilver with mine. Just Aggressive but no CELs.
