Since I had my Warpseed Y pipe installed I get a Buzzz sound at about 1900 rpm, most noticable when accelerating. No buzz when car is in neutral or park.
Is this the symptom of Bees in a can? If so what can I do to quiet it. I've check for lose heat baffles on manafold and cat back everything seems tight. If it is the bees and is normal I can live with it. Also seems sound goes away in rain or wet conditions, but maybe road noise conceals it.

 

that sound usually is fron a loose heat shield or a bad flex joint

 

I've had my WSP Y on for over a year now and no noises from it at all. It's about as quiet as stock. The rest of my exhaust is stock though. As long as everything was tightened up right and there's no exhaust leaking from the y-pipe, you might have one or two exhaust studs broken or loose on your exhaust manifolds (common Nissan problem from this era). Does it kind of sound like a whistling sound?

 

No whistling sound, just a sound very much like a baffle vibrating. somewhere I read that if pipe is not aligned properly it can give you a buzz. Looking at the pipe (installed by local shop) it appears it is shifting cat back of exhaust to the drivers side of center. If I don't get any better ideas, I'll try loosening the 8 attaching bolts and try to shift it. Pipe seems very good quality and I don't blame it. I don't want to bring it back to shop that installed it because I don't trust their work. at the time they installed pipe they changed CV joints and left off or bent right side retaining clip holding axel in trans. this caused wheel to shift setting off antilock brakes every time I stopped because sensor was out of align with axel. First trip back, they said drive it for awhile and let computer reset! What a joke. Then I had problem with wires hanging down from O2 sensor because they didn't attach the retainer to frame at plug.

Biggest problem is finding reliable shop without paying dealers prices. Being winter it is not the easiest to make repairs yourself.

 

guess im lucky to have two great shops around here right across the street from eacn other !

HOW FAR IS glassboro, nj from scotch plains / westfield / fanwood, nj area if your interested i can PM you the address of the shops (the one that is fixing mine now)
