Had mine custom made but I believe MagnaFlow has pre-made ones.

 

Here is a link to the company I bought my X Pipe from. The quality is excellent.

Pypes Performance Parts and Accessories at LMPerformance.com Mid-Pipes (X-Pipes)

 

So this is my xf N/A with x pipe and cat back, 2 nd gear pull with less than half throttle. Sounds a lot better in person as we loose sound quality. Still considering down pipes with high flow cats to get some extra horse power!

 

Thank you fellas!

Yeah, I have had several Magnaflow systems on several vehicles and they have always sounded fantastic and held up well.

Our stock system is 2.5" right? Would 10791 be the right one here?

Cool I didn't see any Jag specific products...did you call, get their advice and order one? Or would one of those fit? Pricing looks a little steep for a simple x pipe but if it's quality I would be interested.

 

Mine was a generic Magnaflow x-pipe. The muffler shop I had my work done at had them in stock and it's simply based on the pipe diameter (which is 2.5 I believe). I had the resonators cut out too and replaced with straight pipe.

 

Here is a couple of pictures of the X Pipe I had made for my car. I purchased the Pypes narrow tunnel pipe & stainless steel pipes for the back & Nameless Performance front pipes with flanges to mate up with the Nameless track down pipes. It was made as a direct bolt in replacement for the Arden center section we took out. The X Pipe took about 12 hours to fabricate but was well worth it.

 

Did you remove Cats on this beast ? Or high flow cats ? Thanks

 

I have Nameless track pipes, no catalysts.

K never heard of them....any emission issues ? Had a CEL recently solved but still waiting for cycles to hopefully clear 4 outstanding monitors .

 

There's no O2 sensor after the cat, so there shouldn't be any CEL issues. If there are they should be transient as the ECU re-adjusts to the higher flow rates.

But if anyone goes catless they need keep their stock pipes so they can throw them back on for their emissions test especially if they do a sniffer test in their county.

 

Any of you guys running catless shoot flames? :P My old STi used to shoot awesome ones in between shifts. It was so loud though, I can't imagine what a catless V8 would be like to drive every day

 

There's two One pre and one post, but post was actually in the cat itself...we think the CEL Issues may be some minor leakage ...we have repaired one ...but not out of the woods yet...was hoping to avoid switching back and fourth...INSP is up next month so need to get sorted out...or put her to sleep for the winter .

 

It's awesome ! But no flames till date.

 

When are you going to post some intake pictures?

TCP just started offering a 5L intake for all those 5L guys. I think that's is the first 5L intake on the market at the moment.

 

I've done some research on metal intakes and after speaking with Eloy Way from RPI, I wouldn't do one. Although it's better looking than stock, it will also retain a lot more heat than the stock plastic tubing and whatever gain in volume you might get, you'd lose the same or more to heat.

I'm more inclined to cover up the resonators for more intake sound and supercharger whine and leave the rest stock. I might also decide to wrap it and the air boxes for better heat insulation.

 

I wonder how many people have data logged their IATs. I have and they were 25-30° above ambient cruising at 70 mph. On my STi and Edge they are normally 10° above ambient.

I am tempted to get some insulation not even header wrap just to see what kind of reduction we can expect.

Another issue i have with our intakes is the radiator hose that runs right next to the passenger side intake when it makes the bend to the black cloth like material before it enters the air box that is another area that should be insulated as well.

Being an engineer trying to solve a problem that doesn't really matter is so much fun.

 

I'm sure we'd all like to know what the data says. Do it and let us know! You've already got the before number.

 

To add another data point 62° ambient tonight steady 50 mph intake temp was 104°

On a longer stretch of continuous driving it may have gone down a little more.

I will get some insulation and see what the numbers say.

 

Are you taking that temp through Torque?

 

Yeah
