HI ALL

Well i finally got arround to fitting my FLYEN dump pipe, the bellmouth one. I have new gasket on the turbo to dump, but old ones on the cat.

Now for two days it was fine, but now, when you start it, it almost sounds like there is an exhaust leak somwhere, but inside the pipe, does it when warm too.

I have gone through all the bolts, all nice and tight, cheacked for leaks, can't feel anything, anywere. turbo, cat, manifold, all good.

The car still pulls like it did, no loss of power or anything.

You can't seam to hear it directy outside but more inside, like inside the pipe. I am thinking that now that the O2 sensor is more in the flow of the turbo, maybe that is making the sound.

I am going to get new gaskets for the cat, and put them in, just to make sure. But has anyone else had a simmilar problem to this?

ANYONE?

nope no high temp sealer between the dump and the turbo, no need, i got a genuine copper gasket, and was told not to use any, nobody i know has, and it is definatly not leaking from there, tripple checked now.

I got new gaskets for the cat, as they are the ones i have not changed, so i will replace these tommorrow night and see where from there.

It is like a leaking noise, but it is inside the pipe. BUT i do not notice any performance loss at all.

ANy other ideas?

      Or the brand new throwout may be unhappy...

      Thanks for the linkie. Certainly always a great deal of help when people post comparisons like these, but I think for now I'll stay away from any semi slicks. I did go ahead and order the sportcontact 7. My buddy has them on his modified A4 and he keeps saying how good they are. For my intended purposes these will probably work real well. I'll report on them once I had the chance to try them out

      Talk about noisy. Even when I still had the Tomei under the car I could distinctly hear the tires rolling. And I doubt I ever will need maximum grip like on a track. My GTR will maybe never even see the 600hp mark and I need to get used to the car quite a bit before challenging the limits of its handling. For the next winter storage I think I will get a set of these rubber drive-on thingies that have a tire shaped base. Those supposedly really help prevent flat spots.

      Well our climate is definitely way less hot overall and the weather can be quite picky at times. I just know that during normal road use or even spirited drives there is no way I'd be able to consistently stay in the operating temperature, and constantly changing the tire pressure would also be a royal pain.

      Input shaft bearing. They all do it. There is always rollover noise in Nissan boxes - particularly the big box. Don't worry about it unless it gets really growly.
