I had my Cattman Y-pipe on for about a week now.. I noticed besides the banging I get (probably hitting the cross member) I also notice that the car just shakes when I'm idle or stopped in D. Best way to describe it is, feels like your on a bridge and 10 trucks pass by you while your standing still.. Like ripple waves.. Anyone get this?>

 

hmmm.... no idle problems here... What is your idle rpm at? Your car may need to 're-learn' the idle speed. Reset the ECU and see what happens.

 

Hmm, I got that in my 4th gen was idling... Never knew what the problem was. It felt like something was clogged in the muffler and everytime it "huffed and puffed" the car would shake with that pattern.. don't know how else to describe it, is it similar to this?

 

I never had that problem.

Get ready Nauman, I just bought that Cattman SS Ypipe. Definetely cant do this alone or without your jackstands.

Hopefully this aint a bizaaaaaaach to do. I know you said the the bolts up near the header are the ones we might have problems with.

the only problem that i have had similar to this one is when my old maxima was skipping, i stopped in my driveway and noticed a shake, got out and looked at my exhaust and it was actin kinda funny too...turned out to be a bad spark plug wire...only thing klose that i have experienced.

 

My RPM idles at about 11-12K... But sometimes the rpm start to drop a lot lower when I haven't started the car for a while...

 

uh-oh... hehehehe... congrats! We should block off the entire day for the job. Some of the bolts can be a real pain.

 

Damn the entire day? Uh-oh.......

 

well, maybe just the afternoon

 

Cause you know me, I am liable to start that bastard on my own, and have it half completed by the time you get there.

when do you get the pipe? Let me know when you want to hook it up... just drop me an e-mail.

 

Sounds some what similar.. Were you able to resolve it? Or was this just part of the Y-pipe breakin in. Maybe it'll go away after like 1K+ miles?

 

Sweet! you must be the first person to have put a gas turbine in your Max. Do you have a write-up on how to do? How much will it cost?

Take pics and post a write-up if you can Bigdog.

Did u get ur custom B-pipe yet?

 

IM all about pics and write-ups now. I am out of control on that crap.

maybe you damaged an o2 sensor while installing the y?

The install is not that bad. All I used was some hand tools and a pair of ramps. Took me 1 hour to get the old pipe off and about 1 hour to get the new pipe on and torque it down. Just make sure you have a deep socket set and an open wrench for the 02 sensors.
