anyone else with test pipes get this.....?

fuct · 12-20-2010, 01:22 PM

I have a set of CNT resonated test pipes as my only mod, and i get this nasty black residue on the back of my nismo. im guessing the cars areodynamics are churning it up and depositing it....?no? i can wash the car and drive to dinner and bam! already a thin layer. these pics are from waiting two weeks to wash.

its not tires being eatin' up, ive had an alignment done.

anyone else? am i running stupid rich?

O_O
wow! thats a lot. I know some of it is due to the test pipes...spitting out more exhaust residue than a car with cats. But that looks extremely exessive...and it doesn't help that your cars white and it stand out that much more...

fuct · 12-20-2010, 02:09 PM

yea this is the worst ive had it pictured above. sux because i keep her really clean....

SE · 12-20-2010, 02:22 PM

Mine is pretty bad also..not as noticeable as yours though due to my PG paint. I'm running LTH + resonator deletes. It's normal.

Check for exhaust leaks just after the primary O2's. A leak near them can cause readings to skew lean, seriously raise positive fuel trims, and result in you running rich.

Is the CEL on?

fuct · 12-20-2010, 04:03 PM

yea i have a check engine light, but thats just the crappy O2 sensor mounting location.

i even used grade 10 automotive bolts not the crappy ones that came with the test pipes.

i will go back under and recheck every bolt.

eh normal..dont forget that you have white too. i have HFC's and my while thr front of my car is clean, once you see the trunk its disgusting. especially after rain! the wing shields the car from rain, and the brake dust and exhaust just sticks there.

even before i installed my HFC's the back of mine would be covered in black dust, while the rest of the car was relatively clean. thats why ive thought about installing some sort of a pull harness like most SUV's have for closing the trunk. keeps fingerprints off the hatch haha

Try using the trunk latch to pull down with your finger. Takes a little practice to get right but I always use it on mine.

wow thats alot. Never seen that happen before.

One_Quick_Z · 12-22-2010, 02:59 AM

WOW that is not normal... I have a white Z also with test pipes and exhaust and it has never got to that point, If you do not keep it clean on a regular basis that will stain the paint.

I already get a little soot back there even with just the stock exhaust... I guess this means it's a HELLS NO to test pipes for me =P

Are you sure the code is for the cat and not high fuel trims? What code is it?
