    That sucks! Put a shop rag in the exhaust until you get around the corner.

    yea, I got 40 series too, and they are pretty load... If your mom wants them to be a bit quiet then 40 series are definately out of the question...

    The 50's are cool. Pretty quiet when you aren't gassing it. But if you need to gas it nice deep throaty sound! So on your street drive slow and keep the noise down....on the high way rev it up and get loud! [​IMG]

    (PS ask Muddin4fun what she thinks of hers, she has a 50 series)

    The 70 series flowmasters are what you want. I'm running them on my 89 and like them a lot. They still flow real good and are fairly quiet at idle, low rpm, and highway. But when you step on it they bark real nice. I get compliments on how healthy my K5 sounds. My wife drives it all the time and hates loud exahust. She even likes the way it sounds.

    If I were you, I'd just explain to your mom that loud is good. I have the 40 series on mine with dual. I still live at home with my mom and basically said, "mom, it's my truck, my money, my pipes. Now get out of my mix!" She just laughed and said, "I don't want the neighbors complaining." They haven't yet, but I don't think they have the ballz to say anything. I ride it hard when I leave to go anywhere. Nothing sounds like a Flowmaster!

    I would go with the 50 series delta flows. You get the sound you want almost two thirds less neighborly whinning. And not get into the throttle on your way in. There is nothing that you can do when your neighbors complain. Mine always tell me that my truck is too loud, at least, when their wives are around. Catch my drift[​IMG]. So for now just ease back on the throttle and coast in as much as possible.

    Get the 50 series. I can barely hear it running at idle and below 1800 RPM. Above that lookout and hold on to your ears. With my zz4 with headers and no cats it screams. Sounds like NASCAR from 2500 to 6500 RPM Real cool.

    Here we go...[​IMG]. As some may know [​IMG] I have dual 50 series. Nick drove the truck by the house the other day and at just an idle, you could "feel" it and hear it pretty good. It's okay passing by, but to someone who doesn't like the sound of a healthy eight, then it might be a little annoying if it just sat there ideling for a while. If you are putting a single muffler on, go 70 series. That'll make everyone happy. If you're going dual mufflers, then 60 series will be quieter then mine. A single muffler exhaust will be louder then duals. That's what I suggest. The funny thing is, my truck is better insulated than my house! LOL! I can barely hear mine while normal driving. But when floored....alarms beware!!!!

    I run a 3 inch single Two chamber with no cats. My advice is save your money and don't gas it so much....then get a louder stereo, she won't even hear the exhaust then!!

    Go with the 70 series and a cross over or "H" pipe. The cross over will make more torque and make things quieter. I have a single 2.5" and a 70 series on mine and I think it's quiet. When my neighbors say it's so loud I just tell them "No it's not" and smile. I'll have my '66 Chevelle with a 396ci running again in about 2 more weeks. I have 3" 2 chamber 40 series on it. They just don't know what they're in for!

    i love my dad's 50 series. it's an awesome throaty deep roar at 2000-5500 rpm but at idle it's a deep throaty purr. /forums/images/icons/grin.gif /forums/images/icons/grin.gif /forums/images/icons/grin.gif

    I have Dual 2 1/2" with 50's on my K-5 and wish I would have gone with the 70's. A friend has the duals /w 40's on his El Camino and mine seams louder.

    So I say 70's
