Why is one anti-fouler bored out? I was thinking the smaller the hole for O2 sensor the better. I know you read up on the TP so I guess I'm just missing something here.

So CEL aside, how is the butt dyno?

 

Brad, one of the anti-fouler is bored out because the o2 sensor cannot fit properly and cannot be screwed on without doing so. If you actually look at the spark plug anti-fouler it's to small for it to fit. Aside from the CEL, the butt dyno feels awesome! I say I gained a few ponies but not sure how many. You should get it! It's actually a little bit louder but like a deeper louder nothing annoying though.

 

Isn't a hi-flow cat a better bet? Maybe a bit more expensive up-front ($300 vs. $70?) but less hassle than four anti-foulers/o2 sensors, CELs, & putting the cat back on for emissions tests...

 

My personal choice would be a hi-flow cat too (I'll admit it, I'm a partial tree hugger) but there are no emissions tests over here.

Tu, I know what a pain in rear a simple ticket can be on base so I was wondering what the Air Force policy and fines are for operating a motor vehicle without a cat. I just know they randomly inspect a high number of cars entering the base. Do they use on of those mirrors to search under the cars for WMDs and such?

 

Don't forget the smell too! My car stinks and I feel bad for anybody behind me.

haha.. It doesn't smell that bad IMO. But yeah 2006+ sucks at cooperating with aftermarket testpipes After 4 spark plug anti-fouler 1 CEL fix that came with the testpipe and it still threw a CEL. Oh well... it doesn't matter as long as I know the CEL is from the testpipe.

 

Have you had the cel checked to make sure that it is the test pipe causoing it.

 

Don't know about that but mine threw a CEL recently (on std cat & exhaust) - turned out to be a bad o2 sensor...

MY06+ deserves a hi-flo over a stink pipe

 

Where do you go on about getting that checked?

 

After replacing your o2 sensor did it still throw a CEL? What testpipe are you running btw?
