I wil soon have time to work on my XF that ived had for three yrs, coming off my second deployment in three years and wanna mess with my baby! Im contemplating a new exhaust for the XF. My idea is to remove the rear cats and run a single pipe to the stock exhaust. I also want to open the muffler and remove all the insulation and the perforated kidney things inside then wrapping the muffler in sound heat/deading material . I am wondering of the possible negative effects on it. Is it goin to mess with the engine at all (backpressure). Im lookin for a deeper sound out of the exhaust. Thoughts and experience much appreciated! Some other mods i wanna do are a CAI ,Eurocharged Tune, Injectors, NK plugs and Magnecor 8mm wires. Ay ideas about HP gain with these!

 

If you're just looking for a deeper sound, i'd go with the Megan Racing M-RS muffler. It's a "universal" type, that is not a direct bolt on, but can be easily made to fit (welding and a small addition of pipe that the dude at the muffler shop had to bend, not a big deal). I have one on my XF ('05 Black N/A Coupe), and it sounds REALLY deep. Bit of a drone at freeway cruising speeds (65-70mph in 6th gear), or at low RPM in 4th gear (40-45mph).

I have a crappy vid of my car before and after I switched mufflers. I'll post it for ya. There are some other vids on youtube as well. If you just want it to be loud, and deep, and don't mind the drone (it's really not that bad), i'd go with this muffler. Oh, and did I mention it only costs $149.95. (Megan Racing Muffler)

And here are a couple of pics (more in my gallery) of the muffler on my XF.


(I know it's dirty, but I was just so excited when I took the pics... )

Edit: Feel free to PM me if you have any questions!

 

My friend has a Cold Air Exhaust. John (JHM2K) can vouch for it.

 

Ansa mufflers sound great on these cars also. Here is a link https://www.crossfireforum.org/forum...available.html

 

Agreed. I almost went with the Ansa muffler, but opted out because I prefer how the Megan Racing one looks. Personal preference! There are some videos of Crossfires with Ansa mufflers on youtube as well.

Check 'em out and pick what you like best! Of course, there are always other options as well. (Like the MagnaFlow Catback found here at Needswings.com) MagnaFlow Catback Exhaust System



Good luck

Indeed.

It has a trick little iron-oxide diverter valve in front of the muffler, and under acceleration the exhaust gasses bypass the inlet and serve as a cutout, making a nice throaty sound. The neatest thing is the fact that you can literally put your hand on the muffler tip, even after spirited driving. No doubt, cooler gasses = denser gasses and we all know that denser air = horsepower.

 

John I just thought of this. What if we route dylans cold air exaust onto a secondary diffuser. He'll handle just like an F1 car. Well at least until this weekend.

 

Or $90 on Ebay.

 

More win than Charlie sheen in a snowstorm

 

Once upon a time, I should have looked on eBay before I bought it.

Now i'm sad.

Oh well, at least it still sounds good!

 

Hi guy's I just installed my Magnaflow, and I can tell you why there are guys trying to sell them!
I think My wife will make me take it off, if I don't do it first, wow that was a wast of $$$$$ it is so bad in the cabin around 2000-2300 rpm that it will make you crazy!

does anyone know where to get any of the sound dampening material they use to quiet down the hot rods? can't recall the name.

Angelo,
Sorry to hear your modding isn't going very well.

 

What about adding a Vibrant Performance resonator? ; Vibrant Performance ::.

 

My moding is turning out to be way mor frustraiting than working on bikes, between people ripping me off and lack of avalable parts, I think its best to leave these little beasts stock! what a **** show!

 

I tried it. I does help with some of the drone, but was still too loud for me when traveling. I found the "heat wrap" on eBay. I have the exhaust leaning up against the wall now. I may use it again, in beween trips.

 

I think this may be more for heat than accustics, I use it on my motorbike, the stuff I'm thinking of I saw on a hot rod show, it just escapes my memory? it was a sticky carpet like material they applied under the carpet, I was thinking about possibly under the rear carpet in the back, that also looks like a good start though!

Thanks James.

 

I found it, has anyone tried Hushmat? I can get it localy here in Canada, I will try it first, it can't hurt to quiet the cab down anyways.
I sure would like to save my latest so far POOR INVESTMENT

I believe you're talking about "DYNAMAT". You can also use BROWN BREAD or B-QUIET ULTIMATE.

 

Thanks Steve, that will work as well, may look at both, it's worth a try, not sure wher to instal the resonator device, but may call them for advice as they are in Missisagua.

You will need a truck load of it to make a difference with the Magnaflow And your car will be much heavier
