I've got problems can someone help!

[Steady C]

I have taken as good of care as i can of my 1995 J30t. That being said heres my question/problem. I have had an on going problem with an extremely loud rattle in the cat. On my way to work today when i would hit the gas pedal my car would not go anywhere and would slow down dead in its tracks. if I pushed it the car would shift and strain but i wouldn't go much faster. My guess was maybe because of the cat im losing back pressure in the exhaust but im not expert. unfortunately the only mechanic i trust is 600 miles away and i dont think it would be good to drive it that far in this state. Any commments are appreciated. who else to ask but the j30 experts

Your cats could be clogged. When I had mine removed, one was starting to deteriorate and the other one, the insides were all the way gone.

Must be nice to not get emission testing yearly ... Grrrrrr

I thought having to test every two years in Cal is bad. Every Year ?!Your cats is/are clogged, and it is building up too much back pressure. Any exhaust shop should be able to do it.

Agreed -- your cat is done if it's rattling -- that's a tell-tale sign. If it's clogged, your exhaust is severely obstructed, and performance will suffer.

Look on ebay for inexpensive, high flow cats (I bought Magnaflows on there last year, dirt cheap). My local muffler shop put two on my Bimmer for $50 labor. Total cost, around $150 (for two cats).

Good luck.

Dude, do what was suggested right above you post. Find 2 cheap hi-flow cats (about $50 each) and take them to a muffle shop that will install them for about $50. If that muffler shop won't do it, just go to another. Someone will do it and someone will do it for about $50.

The price you are getting it probably stock replacement cats which are high dollar.

The cats at my dealer are over 1,000 each, i would look online they have aftermarket cats for a real good price, you need to find a shop that can do it for cheaper than 850.00 that is crazy, just have a shop blow them out and drive with no cats, That is if you have no Emmison test, here in Florida we don't have any test so you can do whatever. keep looking online, it is not worth selling the car over this little problem.

If you have them hollowed out your car will sound like crap. Been there done that.

If your looking for OEM cats, try on of our sponsers. They're much cheaper than an Infiniti dealer.
