Cattman's Y-pipe still bangs....
 

After inputing a lot of washers to cross member, the y-pipe does not bang during normal driving. But when I try to peel out, and wheels hop, it bangs really bad.
Does anybody have a good solution? what did all of you do?
thnx

You can't use the stock bolt (even with washers). You need longer bolts and more washers - I think I'm using 6 or 7 washers see this pic of my auto max. Ignore the orange cable ( I was experimenting with a Cali to Fed conversion).

Hmm, I just got mine on a few weeks back and I haven't had any problems yet. Nothing extra needed, stock hanger and bolts, etc. What exactly is supposed to be hitting? I photoed the whole install for a guide, but the install guy (nissan pro) didn't see anything wrong either

Upgrade your motor mounts and/or remove the cross beam since it does nothing anyways.

Bangin'
 

I did remove it when going to the store to get more washers and longer bolts and it didn't make noise.
I am using longer bolts now with 5 or 6 washers and extra nut inbetween, that the cross beam is even lower now then the resonator.
I have the old design, and I'm afraid, that when I take it off, the pipe is gonna move/wobble so much, and nothing is gonna be there to bang off of that it will come apart or something.
Could that happen?
I'm really ready to take off this stupid thing, it weighs twice as much now with the longer bolts, extra nuts and washers.

No real solution other than stronger motor mounts.

A motor mount upgrade definatly does help. With my new poly mounts my wheel hop has been drasticly reduced and so has the banging noises. As for removing the crosse beam.. I have to disagree with you there. I removed mine and found that the car had a lot more sway to it. The whole car felt like it lost a lot of stiffness.

I got one question. Is this the new y-pipe with the rear hanger on it cause I am looking on getting one. is your's the YG5 or YG5/CA.
