I put a high-flow cat on my GTI. Once a month is throws a CEL for the cat. Luckly in Florida we dont have emissions.

 

Hmmm, why does it do that? Any ideas?

 

High flow is not as efficient in "cleaning" the gasses.

 

Ah, so just a regualer cat will be good?

 

For performance, you want the high flow. You can use a 02 sensor "spacer" which should be enough to avoid the CEL.

 

OK don't really feel like playing 20 questions....
Why don't you just tell us/me what we need to do??

 

Your local part store should have it.

Go the the "HELP!" brand accessories.

You want the Spark Plug Non-Fouler
Part # 42009 (or 42002)

It comes with 2, you will need both.

Drill one of the foulers with a 1/2' drill bit. This will accomodate the head of the O2 sensor.

Fit the O2 sensor to the bored out fouler, fit that combo to the other fouler and lastly, fit all that to the down stream O2 bung on your header.

It will make sense when you see the parts. Hardest part is the drilling. It is not that difficult.

I'll take a picture next time I am under my car.

 

Sweet, thanks!

 

Sounds like you'll have your hands full for a little while racer! Sure is nice having you back, seems like we get more posting from everyone once you came back!

 

He's our inspirational leader! How are we supposed to function without our leading poster?

 

lol, I'm just a big fan! Besides, i gott'a keep you boys in line...
:-)

 

I figured out how to get 300 horses out of my XK ... buy the 2007. (You get awesome looks too!)

 

Yeah, but if you want awesome looks and a Jaguar with awesome performance, then get an XJR or an S type R. The new XK looks like something of a mutant of the Aston Martin!

 

Whats wrong with that? Its also more than 20k cheaper!

 

Aston Martin and previous XK shared some components like door mirrors,climate control .It's not but still can be said a rebadgedJaguar with more expensive price .I think it wasa Ford thingy to eliminate the costs lol .

 

It is definitely a taste thing! If I have a Jag, I want for it to scream JAG! The XK screams ASTON! I like the Aston, don't get me wrong, but I think that the Leaper is trademark Jag, and the XK doesn't have it, and it just doesn't look like a Jag. It is beautiful though, I'll tell you that!

 

There pretty much switching to the leaper-less jags though. Especially when the leaper is only here in the US...

 

I guarantee that I'll put a leaper on the new Jag I'd get if it didn't have it already! I'd buy one off of ebay and I'd drill a hole on the bitch!

 

Yeah, I love seeing it on there and washing it!

 

However you have to decide what leaper you will get and don't forget each leaper have different mounting holes .
