I just put a rice pipe on my car, and at startup it makes a terrible amount of noise till it gets warmed up. Does anyone know of a way to quiet this down? It sounds like something is wrong with the engine.

describe the noise... also, put your factory box back on to see if it still does it

Nothing'* wrong with the engine, That'* the sound of power.

actually it'* the sound of turbulence, find something not smooth, and smooth it.... might just be the Iat or something...

I still have the MAF screen in b/c the pipe is a little short, its like a whisting gurgling noise. It starts to go away after the engine temp is above 100*.

Thats the natural sound an engine makes. Go run it up to 5k RPM and then you'll hear it make some noise

Did you have a filter on? MAF quiets it for sure. Otherwise build a very shielded box. There'* nothing wrong with it at all though.

i know there is nothing wrong, it just sounds like crap for 5 min, then it sounds good. Im wondering if it has something to do with coolant, since thats what changes as the engine gets warmer. If I had a drilled tstat would it help?

thanks for the help. I went outside today and noticed that about 30 miles on it and all three clamps had loosened. I moved one of them and tightened them all up. If I have to keep doing this then I am going back to stock.

The EGR has a lot to do with that sound. The clamps should settle in soon.

Will rubber be able to withstand the heat in the engine compartment or will it gradually melt over time? I suppose they were just settling in, thats why they were loose.

My dad went to look at digi cams, so when we get one ill have pics up of my ride (after I have been a member here for like a year )

Macho i finally got my own digi cam after using the rents till this weekend.

But whenever you make a CAI box for it, use a lot of insulation.
