vortex exhaust for silverado

[SIZE="3"]Has anybody heard of a vortex muffler ? i met a guy with duals on his p/u and he said they were vortex mufflers and the he drove off. it sounded real nice, just what i was looking for in rumble. i have a 2000 silverado extended cab with a 4.8. who sells them and any recommendations.

thanks

I run Magnaflow on my 5.3l and it has a beautiful rumble, ill try to make a video of it

I was actually thinking that I should have tried this kind of muffler:

I have the Magnaflow on my 5.3L as well but, had to put a High Flow Flowmaster Resonator on it to help with the in cabin resonance. At 1500 RPM it was unbearable in the cab. I was NOT Happy. If I was to do it again I would try the Aeroturbine or stick with Flowmaster...

hm, my magnaflow is perfect, It could be a little louder outside, but it has a great rumble and inside its quiet

From the inside the windows were up. Just enough rumble to move the camera :naughty:The damn clicking is my cameras shutter trying to block the sun...never noticed it was so loud. Its a good camera but when I compressed the video's they lost a lot of quality. From the outside I did a lil above 2k, then 4k rpms, It rarely farts at 2k just happen to do it today. The stock 5.3 exhaust came with individual cat's and had a 2 in 1 out muffler, I just replaced it with a 2 in 2 out magnaflow so i suppose its true dual. I kinda like the way both come out the same side, it grew on me

That sounds mighty mean. I suppose that's what I should have done. My truck came with an original Cat back. So Single in Dual out. I should have found a way to do dual in dual out.

I'm really happy with the way mine sounds now and it's get's a little louder as it starts to really brake in. If I get some time I too will take some video...
