i do not know what i want, tps or hfcs..

 

EWW test pipe just sound bad....

I rather get high flow cats with less rasp and exhaust pops....

 

speaking of exhaust rasps..my exhausts recently started doing the loose change rattling on cold start. guess im visiting my local infiniti dealer soon.

 

From what I understand, it'll just happen again.

 

your kidding right..wtf.

 

^^ you should check out FI's test pipes... how are you gonna get around the check engine light?

 

just do the cel bug. I did it on my S2000 and it works fine...

 

^^^ ok i'll bite CEL BUG? whats that?
This is the first car I have worth moding as ytou can see from my sig.

 

Here's how it to do it:

1) Buy a set of 18mm Spark Plug Anti Foul Adaptors from the autoparts store. they come in a pair in the little red "Help" packages. These things are designed for cars that are burning oil and fouling it's plugs.

2) Drill out the small hole of one of the plugs to 1/2" diameter. This will allow the O2 sensor to screw into the plug while a tiny bit of room surrounding the sensor.

3) Screw either 1 or both adaptors together into the 2nd O2 bug on the cat back. Carefully screw the O2 sensor in. Don't overtighten since the adaptors are now pretty thin walled due to the 1/2" drilling.

 

here are pics of what the fix looks like. the first two pics show my o2 sensor destroyed from the tp, second shows the new sensor.

 

here is the fix for the cel.... first pic is the two plug adapters. the one on the left bottom is the one that is drilled out. the other is normal

Second pic shows the drilled adapter screwed on and how it hides the 02 sensor from the excess gases because of no cat.

Third pic shows both adapters installed both the drilled first and the non drilled second.

Fourth pic is the o2 screwed back into the TP.

 

Its a very simple fix. the idea is the secondary o2 sensor reads the gases coming from the cats. when it senses that it is reading too much of some gas i.e. because there is no more cats with tp it throws the cel. The bug places the o2 sensor not only farther away from the gases flowing through but also reduces the amount of gases it can sense which in turn makes the ecu think everything is running normal and fine. so no cel. works everytime...

 

Gonna have to try this...

 

Any word on the Group buy yet?

 

Do these and/or the testpipes work on the 07 + g35 sedans?
