Spintech. Haven't installed mine yet but read great things, watched lots of Youtube clips and talked to the owner for a good bit.

NOT hooker aerochambers. I have one on my regal and i think that it may be the reason for the latest crappy rattle vibration ruckus i am experiencing. Plus, it drones if i correctly recall the sound it made new before it started making even more noise. From what i have gathered these mufflers had qc issues and the parts inside have likely come loose based on what i have read from others' experiences.

I currently run FM series 70's with an H pipe, the tail pipes exit behind the rear wheel as well. At average highway cruise speeds, I have a drone that resonates in the suburban cabin. It's not too terribly bad, but after a while of listening to it I want it gone.

For the '70 K10 SWB I plan to put in the Dynomax "Hemi super turbo" mufflers, since it is a short length of pipe and I want it some what quiet on long drives.

I have flowmaster 40's on my 383 with cheapo flowtech headers. Sounds good at the stop lights but has a drone at highway cruise, But I have a set of thrush welded and a new set of doug thorley tri y's sittn in the garage ready to install.
I would say go to you tube and listen to some sound clips (they have any kind of muffler you could think of) and find what you like (thats what I did) I like the rumble the thrush has but seems to quiet down with acceleration 9at least from the sound clip) I guess we will see

Those Thrush welded chambered mufflers are a great value...I believe there repackaged by Summit as one of their house brands, slightly cheaper. Got one on my Yota ....no complaints, I'd link a sound clip but they may kick me off the forum.

I guess I'll have to take you at your word I figured for the price I can't go wrong. They were 35 a piece and from what I've heard they sound good. I don't mind a good rumble at idle and a bark at acceleration, but I DO NOT like my truck screaming at 3000 rpm....Loud is cool but quiet is comfortable

If you don't want it to drone exit your exhaust out by the back bumper. Mine is loud but no drone, I only find you get that drone when you dump it under the truck or in front of the wheels. IMO
