Would the exhaust be able to fit a 2010 XF S/C? I'm new with Jaguars so I'm not sure if the exhaust mounts are the same. Cause if this is mountable on my XF it does look more promising than the X force mufflers I've been looking at. And how much did ryan quote for the mufflers?

 

 

Thanks for all the good info here guys.

Ardent x-pipe w/o muffler just added.

I wanted to get a little bit of a deeper sound out of her so I added the Ardent X-pipe (w/o the muffler) just this week. To my surprise adding the x-pipe in combination with the Mina mufflers did just the opposite.. The exhaust tone became quieter to my surprise. I used a dB meter at start up. With the stock mid-pipe and Mina mufflers my peak on a cold start was 76dB. With the x-pipe installed the peak was only 71dB.

When revving while at a stand still the exhaust tone is good, not as deep as I want it but good. A tiny bit deeper over the stock mid-pipe. The big problem occurs when driving past 3k R’s. The exhaust note complete fades and the car gets quieter at WOT... It almost starts to sound like a weak V6. It’s been 3 days driving like this and it’s becoming very infuriating to say the least. What’s more, the tune is completely out of wack.. tremendous power loss. I know I need to re-scan her and get it re-adjusted to fix the issue. I reached out to Ryan and I’ll be ordering his mufflers, and then once I get those I’ll get her re-tuned.

So the bottom line here is save some time and don’t try to pair Mina mufflers with the Ardent X-pipe.



That’s my kitty

Have you ever got to adding on the x-pipe?

 

XFR-S Beast I am getting these headers with a larger diameter (3.0" dual) exhaust and valved exhaust from Varex installed on my XFR, Id be interested to see if mine is the same or more HP and deeper than yours. I am moving to Pheonix in January so I'd like to meet you and compare them. Engine masters did a video of a V8 with dual 2.5" to dual 3" and dynoed them back to back. They picked up quite a bit of power everywhere and the engine made 600+ hp. I want to see if I can hit 700hp. I already got stage 2 clutches for the ZF trans and plans to fortify the rear end. Who tuned your car there? I was looking at tuning companies there and UMS seemed competent and Goodspeed has a nice dyno facility.


Roman your car is gorgeous! I wish my wheels were that color.

 

these motors for some reason need back pressure

 

The backpressure itself not an issue. The backpressure expected by a tune - is. With correctly adjusted tune you can have no mufflers, no cats, x-pipe and still remain at a same power level (actually the x-pipe itself allows to get some gains)

 

Can anyone with the ardent mufflers/silencers confirm it's 3 wires to each valve?

 

Made the purchase and can confirm these are controlled via a 2 wire, pulsed controller. I've almost finished the relays and controller but I have these setup to run from the factory dynamic mode button. Let me know if anyone else is interested. I put together a quick clip since before and after videos are always asked for. Unfortunately my first time out with the Ardent mufflers blew my mic so you can't really compare the stock to Ardent but you can hear the difference between valves closed and then open right at 3:35. Cannot recommend this purchase enough. Exhaust is throaty with the perfect amount of volume. Very glad they are valved though because wide open is all the time would be too much.

VOLUME UP

 

Gents, everyone I talk to about putting headers on my xfr tell me there is very little power to be gained with the headers based on my current exhaust. I have center section removed, mina axel back. I look at the headers (ardent) and I look at the factory exhaust manifolds and cats and have to believe there is power to be gained by removing the cats and putting on the headers, the motor minds tell me the little i will gain isn't $3k worth. I want to do it but can find something better to do with $3k if i'll gain 25 rwhp. Someone have dyno sheets to educate us that wonder? Racer 69 Shane has some amazing youtube videos proving everything he has done he just hasn't done exhaust yet.
I did pm the guy who has the xfrs that seems to be over the moon and talks like 80 hp with the full exhaust but nothing to prove it, once again I show that post to people who work on supercharged cars and they say not possible
thanks

 

I think when it comes to the headers or a "full" system for that matter you have to need it. You're helping the engine breath so if you've done upgrades elsewhere - pulley's, tune, etc... so your engine can take advantage of a freer flowing exhaust coupled with another tune to maximize that exhaust then you'll see benefit. But I agree with others, just slapping it on without needing it would be a waste.

 

ML so with upper lower pulley/ tune/ x pipe and axle back your take is..... worth the 3K or not? Understanding that each of us have varied bank accounts and how much some HP is worth. I am fishing for thoughts here because we a Jaguar guys and what works on a corvette or mustang will be different on our cars. This is my first non American made car I am a rookie and freely admit it

 

Sounds similar to my Mina Gallery exhaust.

 

Hey, with those modifications it should be more than enough to put smiles on your face! My buddy has these same modes (except the lower pulley) on his Audi A7 with the 3.0 SC and he was doing 4.28 sec 0-60 with upgrades from a stock of 5.2 0-60. Plus he just added the TCU tune and it went to 4.0 secs flat all on pump gas without any weight savings in 38degree weather!

 

I've had everything but the lower pulley and axle back exhaust (I removed the valves in my stock exhaust) and the tune and x-pipe are mandatory. Having a shop remove the valves in the mufflers doesn't cost much and provides better sound,. It's not anywhere near as loud as an exhaust though. I actually prefer my car without the upper pulley. Had the car tuned about a month before sticking the upper pulley on and had it on for a number of years before the supercharger coupler failed. Back to stock pulley and it's a better day to day car. Less lightswitch throttle behavior. Was always curious about the lower pulley. But I make enough power and my car is old enough now that I would hate to have some sort of failure when I enjoy the car so much. If you can do only one, do the tune.

 

kyanite are your power numbers dyno rwhp?

 

Everything I've ever posted about power are rwhp numbers. If you look back at my old posts, you will see dyno graphs and power charts. I figured if it wasn't dyno proven, with before and after to see the percentage increases, it wasn't real.

 

Price went up on the Ardent headers.

 

Yes... yes it did

 

Funny you two posted this in the past week... I have had Ardent exhaust on my XFR-S for 2.5 years and loved it. Considering the headers that used to be $2800 and are now $3750, ouch. Going to look into all the other mods to build this with some power gains seems it's attainable within $3K-$5 to do everything else like the pulley, tune, intercooler. The headers seem a little overkill for minimal power gain but would consider doing downpipes- I wonder if Velocity AP's 200 cell cats for $1300 are a far better investment than headers, or if I'm supposed to do it all. Lol. Time will tell
