I've looked and read and still am unsure.

The most logical thing I've read is that the test pipes without the oem cat bracket causes too much flex and causes the x pipe to crack.

I did not re use the oem bracket and have a serious rattle at idle and deceleration.

I'm going to but the bracket back on and the same post was updated saying that fixed the problem.

Just seeing if anyone else on here has any insight or this same problem?

Without seeing the set-up I assume that the exhaust manifold is an immovable fit. And the first fastener for the exhaust is the first hanger. Everything between, including test pipes, are free to move and contact something. Plenty of room for vibration and rattles. I always recommend test pipes with a support bracket.

Thanks for the reply, ya I'm gonna try and throw and OE cat support brackets on and hope that fixes it. Worked for one poster I saw had same setup and issue so let's hope.

I have the same exhaust set up on my 04. I have the same problem. Rattle on the decel and at idle. I wrapped with heat wrap and it deafened the sound but the heat wrap eventually fell off and I'm back in the same loud rattling situation
