Jaguar XJS V12 Headers + Straight pipe | PURE SOUND

[@Juanknes]

These cars sounds ridiculously well, better than 99% of any modern sport car IMO. Could be in the same league as the F355 sound wise.

[@equalevolution5563]

Awesome! Sounds like a large litre dirty old American muscle car but with the high revving Italian v12 sound. What a mixture.

[@NombreFrancisco]

I don't know what is more impressive, the Jag or those streets. Living in a city sucks.

Great sound! You really really need that manual transmission though. Have you considered a 5 or 6 spped conversion? I have a getrag 265 (using an adaptor plate from Simply Performance) on my V12 but TKO and Tremec options are available I believe. Keep up the good work: I enjoy your videos 😀

5.3 bored to a 5.7. Nothing wrong with the current engine, I just want to try and build a 5.3. Head work, pistons, modified intake manifolds or ITBS, exhaust manifolds, lightened internals and new ECU. Not to mention that it’s a lot easier and nicer to work on the engine out of the car and on a stand. 🍻

A 5 speed gearbox is a must have and better muffler for a clean sound. It's sounding very tinny. In Harry's Garage is a better XJC V12 with a great sound.

[@TechnoJonny]

That auto box ruins that car, I think it's only a 3 speed as well 😳, any sort of performance car should have a manual gearbox.

[@Cosworthcrazy]

I like what you did with the bumpers - much more elegant than the originals - looking at that exposed front valance, looks very much like the XJ saloon, I would not be surprised if XJ Series 2 front indicator/side lights bolt straight on...

[@JulianGriggs]

Thanks man! I’ve also removed the front bumper mounting brackets. I’m using the side markers as blinkers! Looks good. You can see what it looks like now in this video kzbin.info/www/bejne/g3PNgoaDn8qMf6c 🍻

[@JulianGriggs]

Thanks! Manual coming soon!!

[@trbossdoggy]

these cars mostly came in auto. No manual V12 from factory.

[@Cuude]

I feel like it would sound insanely good with a mild/medium cam. Would probably need a full boar turbine muffler and/or x-pipe

[@JulianGriggs]

Cams are for sure happening. I ran an X pipe with the stock manifolds and it sounded pretty good. I am now running a two into one merge set up, however. I think the diameter is too big. Instead of 2 1/2 to 3 inch, I think I’m going to scale down to 2 inch into 2 1/2 inch.

I’ve just picked up a second hand tt extractor system and I’m gonna fit a magna flow x pipe and see how it sounds . Wonder if adding mufflers to the end effects the v12 sound negatively as to fitting any silencers before the end of the pipes ?

I don’t think mufflers are a bad idea. It’ll help with the drone obviously. Vibrant “ultra quiet” resonator would be a good choice in my opinion.

[@haeloglobal5725]

Great mate well done . From Uk Did you use the x pipe in the end ?

[@JulianGriggs]

No X-pipe on this setup. When I was running the stock manifolds, the X-pipe did change the tone a lot. It had more of the “V12 tone” forsure. This setup is headers merging into a single 3” pipe out the side. The headers made a massive difference in tone. The video does not do the car justice, I am really happy with the sound the car makes. I haven’t had the car on a dyno since the install but seems to pick up some HP and torque 🍻

@@JulianGriggs I’ve taking the airfl filter boxes and filters off completely on one of my v12s and it’s crazy .

I would drop down the pipe size or put some open exhaust right on the end it will keep it from backfiring.

Thanks for watching. I plan on running smaller diameter exhaust. Currently, it’s 2 1/2 inch to 3 inch. I want to bring it down to 2 inch to 2 1/2 inch, should help it not sound like a tin can at idle/Lower rpm.

The OEM MPG Calculator never goes above 5 MPG haha.

[@tfleiter]

Actually…these are not as bad as you would think. The engine got way more efficient in the “HE” (=high efficiency” version. I think the switch was with the 1983 model year. You can get 16-18 mpg out of them - if you glide through the landscape instead of stepping on it. They used to be fast for their time with a relative high top speed of 144mph….which is limited b6 the gearbox ratios.
