Hi,

Just wondering what success anyone has had with removing the last mufflers on each side. There are the cats, center muffler, 2 more mufflers and then the last two. I am curious as to what the sound would be like and if there is a bit more power to be had by removing the last muffler on each side. It looks like a pretty easy job to cut those suckers off and put a straight pipe in and then put the tips on it.

Thanks,

I'm going to do it eventually. If you have it done, have them cut off the pipes at the prior muffler and install new pipe from that muffler and up over the axle. If you get under the car and look up you'll see why. Jaguar put a nasty crimp in the pipe where it passes over the rear axle. The cross section is probably less than half of the cross section of the straight pipe. That little bit of restriction has to affect the performance, especially on an R.

 

I have replaced both the rear and middle sections with straight through big bore pipes.

The kitty really does growl now even from low down revs,is a pleasant burble at idle though

 

So what silencers are left?
The ones before the rear axle?

Check out YouTube for Jag V12s running without silencers - Glorious! They sound like Spitfires.

Yeah just the front large silencer is left on,thought i best leave it on to keep the neighbours sweet!!!! LOL

 

I took the last muffler out and replaced by a straight pipes from Adamesh. On a 1997 XK8. Sound is louder of corse and nice roar of engine when full accelerating . But , if you are cruising around 1800 rpm under just light engine load , there is a annoying buzzing in the car. Listening to the radio is limited. I only did trips below 100km, but would change back if I had to go these distances every day , just because of this buzzing. There should be something like on Harley Davidson or Porsche where you can switch the buuble- bubble or roar-roar on and off. That would be a solution I would go for.
nice

 

Hey everyone, thanks for the replies. I have had 4 Porsches and several Harleys. The 1st thing you do is open up the exhaust. I will let you all know what I have done and the results. Right now, I am leaning towards new over-the-axel pipes to open up the nasty crimp they put in it and a straight pipe to oval tips. The only problem I have with this approach is that I do not know anyone that can weld stainless pipe in.

 

Well, I changed my mind after talking to my exhaust guy. This guy is an artist and know exactly the sound I am after. He replaced the big muffler in the middle of the car with two straight pipes. The car now just sits and purrs at idle. A few more revs and she starts to growl a bit with no droning. In fact, there is no droning at any RPM. Nail it and she really speaks up, sounds like a refined 60s muscle car. I know I may be giving up a couple of HP by not having a crossover pipe, but I really like the sound of the true duals. I read other threads and really appreciate all of the wisdom and insight everyone shares here.

THANKS!

Pretty much every muffler shop welds stainless pipe. Just because you see it rust doesn't mean it's not stainless.

 

IMO the nice thing about Jaguars is that they are "vewy vewy qwiet'.

If i want noise I will put my plugs in, helmet on and take the Duc for a thrash.

 

But, there are also those who own exactly one motorised vehicle. In that event, it pretty well has to do all things.

 

I too had the straight pipes replacing the center muffler at first, but the uneven puffing of the exhaust really annoyed me after only a few days. Blending them really helped with the X. As long as you like the sound.

 

I replaced the back boxes with SS straight through pipes, retaining the OE quad tail pipes. The sound is great, especially on start-up and no droning at all. Not bad for £180.
