Exhaust Help!!!!!!

[Trey24]

Since my flowmasters made too much noise in the cab while driving 70mph, I had them taken off and they told me to go with the flowmaster 70 series. So I did. They are sad. Can't hear sound at all. They literally sound stock. I'm so unhappy. Surely there is a muffler that will give me some noise, WITHOUT dropping $800.

Any ideas?

Hey guys and gals, any opinions on the Vortex mufflers on a 5.3 Vortec compared to the mufflers mentioned in this thread, like cab noise at 65/70 mph, performance gains, etc ? Thanks

Why don't you guys just do without the muffler like I did.. sounds much better than a flowmaster. All you have to do is put in a Y-pipe and have the pipes run out the back.. will most no more than $400 if that! YOu will get the gurthy sound without the incab noise

i have a flowmaster 50 series delta flow muffler dumped right in front of the axle and its perfect! not loud inside at all. i dont want tail pipes because of how low my truck is, it was way cheap too. less than $100

I have never seen an exhaust job for less than $100 that included the muffler. the pipes and muffler itself is at least $100 plus labor.. unless you did it yourself.

i got the muffler on ebay, paid 40 for install with a pair of 45degree turn downs. whats wrong with that?

Nothing wrong with that, but that is not what most people would typically pay. I am glad you got a good deal.

I have a FLO-PRO 747 on my truck, single in single out. It has a really nice sound at start up, along with a pleasing highway sound. You can hear it, but not too loud. I pull a camper and did not want the muffler to drone while under load. The FLO-PRO is cheaper than the Flowmaster, it is quality build, and has a nice, distinct sound. Mash the gas and hear it roar! You can go to the FLO-PRO website, flopro.com and check out the sound clips. The one that I have is like the one installed on the Lincoln Navigator clip. I think it is a FlO-PRO 767. Anyway, it cost me a flat $100 installed using my factory pipe. I bought a weld-on stainless steel tip from Ebay for $25 to add a little shine.

i just put on dual glasspacks with 3.5's out the back and i am sad to say that it isn't loud at all. i can only hope that when the GP's blow out it will be loud enough. i have got the 5.3

I love the sound of my flowmasters. I don't think they sound to loud in the cab, but after having a 67 camaro with straight pipes, nothing sounds loud to me anymore.

I just finished installing a magnaflow cat back on my silverado. Very nice piece and fit very well. Hardest part was getting the old system out, and drilling out the bolts on the head pipe. Very quiet, almost too quiet!

The quick way to get the sound you want.. is get the Glass packs really hot.. then spray cold water on them.. that will break them up and get you the sound you want.

i tried that, and i also try getting the muffs real hot and then spraying water INSIDE of the mufflers, i have tried a few times. but they don't seem to be getting louder. they are one of the better built glassapacks though. i will keep on trying though

I would not recommend putting water inside.. that will rust out the GP's from the inside out. maybe you could record the sound and post on the forums.

yeah i put water inside and let it sit, but still nothing. anyway i am going to be buffing my truck this week, and going to my buddys shop and cranking the t bars, so i will try to get some pics up and maybe a sound clip if i can figure out how to do it
