    I have the same magnaflow too and love it, you can usually get a used one on ebay or cragislist. I wanted a valid warranty so I got it here. Magnaflow 93990. Also some of the forum sponsors usually have a sale going on. Either way its a great exhaust system, sounds great, and very easy to install.

    Why would you put a bug deflector anyway? ;) I took mine off along with the side steps when I bought mine. If anyone wants to buy a 2000 silverado bug deflector that doesn't rattle $20 aha.

    My bug shield is GM. Never had a noise. However the AVS window shades/vents that i have on, once i hit 70 it starts to make this whistling sound which is pretty annoying, but i usually just turn the radio up a lil and then i dont hear it anymore

    Default whistle

    was curious if you(or anyone else) have experienced the whistle associated with a bug shield. Mine is the OEM one from GM. Not mind blowing but noticeable

    Default Bug Shield Noise

    I installed a GM bug shield and got the same noise. The noise is coming from the plastic flaps over the hood hinges. While driving I moved to the front of the seat and the the flaps were slapping all over the place.

    Yeah mine does it at over 60mph. Very annoying. Dealer applied glue/adhesive to the plastic strips on sides of windshield under warranty-very sloppy job too I might add. They told me that the NBS all have this issue when a bug shield is applied no matter the brand.

    Default Wind Noise

    2003 Silvy with AVS deflector.Bought truck new in 2003.Have lived with the noise all this time. Finally bought some 3m moulding tape(double sided ), peeled back weather stripping on sides of windshield,with doors open, took out the top 4, torx bit screws, left the very bottom screw in the plastic trim on side of windshield, rotated trim piece down, cleaned windshield and plastic with windex and rubbing alchohol. With trim peice rolled down applied 3in strip over factory strip after cleaning it off, then the whole length of windshield parrallel with edge. Then replaced trim,pulled off the red backing once trim was in place properly, pressed firmly over all areas with the tape. Don't worry there will be tape sticking out, then carefully with a zazor blade cut excess without cutting into plastic moulding, pull off. Replace weather stripping, then call it done. Noise gone for good!

    I think I've got this same dang problem and it's driving me nutz at highway speeds and when it's windy out! I have the bug shield and have checked for all and any loose plastic, etc., under the hood and under the wipers. So it appears it's the stripping around the windshield? I'm going to remove the bug deflector and see if that fixes the problem first. If it does, I'll make a call on whether the deflector is worth it or not and try the 3M tape if so.

    I just ordered one from AutoAnything.com ... the EGR (german made?) part number 391921 ... for my '04 Silverado 1500. They were having a 15% discount sale, free shipping (FEDEX ground), and no VA state sales tax ... total price was $50.96

    I take at least one trip to central FL each year (this year, I'll have gone twice)... I also put aluminum screen behind the grill and in front of the radiator... to reduce messy BUG SPLATZ! Thanks for the thread/discussion... the bug deflector won't arrive for about a week (what with cross-country shipping, holiday packages clogging the system and all), but it should be here before I set out on my next 2,000 mile trip to FL (over the upcoming holidays). I'll report back here if the EGR model causes any noticeable noise problems.
