It does rattle if kicked.
And today i took it out on the hwy with my digi cam to record it.
Under WOT accelerating from 40 it misses horribly. it goes from 4000 rpm to 2000 and bounces back and fourth, I couldnt even get it up to 80 mph today. Also in town if i accelerate to hard from a light...say 3000 rpms..it starts to miss.
If you want to see the 45 sec. video
PM ME with your email adress.
Thanks

It may be.

Take your addy off of there. Notice the post in "Notice".

Agreed, sounds like it. See if a muffler shop will let you road-test it (just for a mile or two) without the convertor just to be sure (it'll be really loud, but focus on the drivability), but I think the difference will be obvious as soon as they get the old one off.

Hehe it would be extreamly loud!
Im just curious if it matters what brand of high flow cat i get..

Save your money and gain a few ponies. Just replace it with a straight piece of pipe.
It won't be that loud.

Hmmm well there is no emmissions testing in Alberta...
And it would be cheaper lol

man, youre having all kinds of problems with that thing. but good luck

Its a new problem every week
I call her Bad Luck Bonne!

Oh, yeah... My ears were ringing when I did it, but at least I knew for sure that that'* where the problem was.

You won't gain power by putting in a straight pipe; the convertor doesn't contribute much backpressure and the car systems are designed to accommodate its being there.

You will, on the other hand, smell like a landscaper'* pickup truck from all the unburnt hydrocarbons you'll be spewing. Just put in the cheapest convertor that will fit and you'll be fine.

K ive decided to go with a high flow one.
