Good sound Good price
These don't sound half bad, good and loud. My 77 C10 still sounds kinda like a old farm tractor at idle but they wake up when you put your foot into it. I changed my exhaust from a Y pipe single exhaust to a X pipe dual exhaust.

Works, deep tone on a V8
Bought this to take the place of a factory resonator which rusted out and started to leak. This fit perfectly in its place. The tone of the exhaust is deeper, with a slight increase in noise over stock, however I still have the oem muffler in place. The Thrush muffler cut out the rasp that I was getting when I had a straight pipe in as a temp fix. This is much better. Hoping the packing will last for several years. Note that your results may vary, a shorter glasspack will be louder, and have a raspier tone than a longer one.

Believe it or not, it is quieter than open headers!
Bought to replace the improperly installed Flowmaster on my wife's 6cyl Ford Ranger. Replaced it with this and a standard design exhaust pipe, and while it still has the deep tone, it is not as obnoxious driving around. This lowered the volume a few DB and by adding back the tailpipe, moved that sound to the back of the truck. 95% of the flow of an open header and only 80% of the volume (I'm making those numbers up, but that's what my ears are telling me, so I'll just keep believing it.) NOTE: here is the secret to a great tone boys and girls - the longer the better! I purposely bought the longest glasspack that would fit in the system. The longer the pack, the lower the note. Look at musical instruments - the longer the pipe, the lower the note. A glass pack has the same amount of restriction, regardless of length - diameter and bends are restrictions. YMMV

Seems to be a good muffler to me
I figured I would get something a little louder for my old truck and settled on this. I did not know you could get a muffler for this cheap (~30USD), but here we are. I was expecting this to be louder (~30 inch version) than it was on my 360FE, but its fairly quiet all things considered. I have not way to gauge noise, but I could drive though a neighborhood at 2AM without fear of upsetting the neighbors. It has discolored a bit after driving it and it smelt pretty bad on the first few trips. It may have also helped my MPG a slight bit, but nothing noticeable. Maybe .2-.5 MPG improvement. Overall I am happy. I think my truck sounds better than what the stock muffler had to offer, and with less rust and carbon too!

Worked perfectly for our GMC truck!
These are very well-made pipes, and we were really in need of them. Looked all over for something like this but couldn't find them. These are exactly what we've been looking for!
