Ah, Blueflame - would that be the same company that's just up the road from me?
They used to make TVR's exhaust systems, supplied my FIA approved catalytic converters (the only ones I know of).
Superb company, superb products - and they supply nearly every 'after market tuner' company with their systems.

Thats what everyone else has said to me about the company. i went on the site and it said for the xj6 setup comes with both silencers and resonators. i assume you have heard vehicles with their installed exhaust...( seeing that they are right up the street ) would you consider them for your ride?
BTW.. your car and wheels look great. been looking for those.

I know this is an old thread, and the one linked below is even older ![Wink](https://www.jaguarforums.com/forum/images/smilies/wink.gif)

......but wondered if anyone ever did try out the X300 Mina exhaust and had any feedback on the quality, and also very curious about the sound.
As noted above, a 6 cylinder can sound pretty poor if the exhaust system isn't well done.
Also with the XJR (and other SC engines), just "opening up the system" may not be a good thing as there is a balance between intake and exhaust flow/pressure as designed. I'm no expert on this topic, but this is what I've read over the years. So it would be curious to know from Mina if their HP gain figures were for both a NA and SC X300.

I would leave things the way they are, I opened up my exhaust, made into a true dual exhaust, and lost half my boost. Now looking around for stock downpipes. Dont do it , focus attention on the intake and cooling sc air charge. after that, diff change and andy bracket. Thats all you can do.

But at $800 for two...
I just bought two Aero Turbine 2525XL mufflers which came out to about $190 shipped to my door and my local muffler shop installed both with tips for about $80
After, purchasing Mina's CAI and realizing what I got for the price I paid, all there stuff is overpriced for what it is.

Docs manifolds and downpipes are great because he has kept the design in order to maintain boost pressure, they go from two to one then back to one. Only thing is be sure to keep the o2 sensors in place, check to see if that is possible. Wonder if he can make a pair of shorty headers in order to keep the stock downpipes and o2 sensors, this I would purchase.

I wish I could find proper rear mufflers. My right side rear muffler rotted out, and the left wasn't too far behind. However, I could only find the left side.
Has anyone found an aftermarket unit that won't make it sound like a tin can? I've, temporarily, replaced both rear mufflers with straight pipe, and it drones inside like an old mother-in-law.

If you lost boost pressure in the inlet I think the engine must have been flowing better as the output from the supercharger is linked directly to engine speed, unlike a turbo. So a drop in pressure should mean that the air is going in more easily, perhaps due to less backpressure, and the engine should make more power? Did you feel or measure any improvement?
My XJR6 went much better after I removed the downpipe cats and replaced the underfoor ones with high flow items from Magnaflow. I have tried with no rear boxes, and agree it sounds awfull under normal conditions. I was able to find cheap replacements in the UK but they are starting to corrode after only two or three years. The original over axle sections are starting to rust through and I am thinking of buying the streight through stainless replacements from AJ6 engineering but am worried that they might cause droning, although the standard back boxes would be retained. I would like a bit more engine sound, preferably a nice burble. It should be possible with a six cylinder as plenty of old sports cars sound nice.
